Cool -my 2004 Jaguar XJR has been running excellent with this transmission for 200k miles, some of my colleagues have 320k miles on theirs.. change your fluid every 15k miles and never believe a "lifetime sealed" trans fluid theory because those gaurantees are only until the warranty expires

Gary Ferraro : Thanks for the repair videos. As you know I had problem with my BMW 750li it was not reversing I had changed the transmission cooler lines . Now what I did was I added a extra transmission cooler to the line and I did drained the transmission fluid again this time I purchased a Castrol Trans MAX 10 quarts . But I could not open the fill plug at the transmission. I had to refill from the radiator cooling intake line by using GRACO spray machine . I purchased a 5 gallon empty paint pail which I used to fill the transmission fluid it was very easy that way I didn't have to raise the car . I attached 3/8 T hose to cooler lines at radiator with low pressure from Graco spray machine by filling 4 quarts at a time and started the car for 10 minutes then filled 4 quarts more and started for another 10minutes now when I was filling last 2 quarts it was going in to transmission very slowly but it all went safely. The car runs very smooth like new has no signs on cluster , IT does reverse no problem. The BMW dealers had refused to work on this car I took it to dealer they could not believe that this is running so good one of there mechanic even drove it , said it's impossible how did you manage to fix it come work for us we pay very good but I said no thanks I'm fine with my job. I just want you guys to see that it does not need a new transmission. I'm still driving it runs great and very smooth . Thanks for you videos they are a great help.

Awesome video. Clear and hugely informative. Gary have you encountered customers complaining about the 'squalk' sound when HP26 shifts from 3 to 4? Car is a 2005 Jaguar xj8 with a 4.2. Same trans as you are tearing down on the video. Jag used to sell a 1 liter bottle of 'magic juice' for around $200... but didn't work on all transmissions. Do you know what is the source of the sound? I have rebuit the valvebody... no change, charged all cylindrical seals and bridge seal, car has correct lifegaurd 6 fluid. Please advise. Thanks!

Thanks Gary, I am working on the lepelletier gear train. Info like no. of teeths, centre distance and widths of gear would be really helpful.

FYI anyone who comes across this, replacing solenoids solved my problem, so far. I had slip on 4-5 upshift, jolt on 5-6, and 2-1 downshift bump. Codes came up 4f8A and also 4f86 for 4-5 upshift but no other codes. Originally i just attempted with the bridge and finger seals, but that did not solve the problem. I have been able to test the car on at least one road trip and a few high load shifts, and so far so good. If anyone buys a car with a higher mileage ZF automatic transmission (over 120k miles, 200k km) at the first sign of transmission issues I would recommend this service. I would recommend disconnecting the battery during this service. When putting the car back together make sure the sliding arm on the valvebody is aligned with the shift selector on the trans housing.

Hi Gary, thanks for yours videos. I have a question: I have an Audi A6 Allroad with this gearbox tipe and I've noticed something strange. When I reverse and the car has no impediment, it works normally. But if an obstacle blocks it or I'm trying to push something(like a caravan uphill), the engine goes up to 2000 revolutions accelerating fully but there is no movement. It's like there wasn't much force backing up, but forward it seems to have more strength. The gearbox has about 180,000 miles (300k km) and a new converter. Any ideas? Thank you very much for your help. Greetings.

Thanks for the video. I now understand how my problem gearbox works. Although I'm still having an issue with it. My local transmission shop had 'reconned' my gearbox after it was popping out of 4th/5th/6th and throwing e-clutch faults at a cost of £1600 (about $2k). I got it back and 2 days later did the same, so they replaced the valve body and solenoids (which I thought was part of a recon in the first place) now the e clutch fault has gone but it slips and makes a wooshing sound and throws a ratio monitoring fault clutches b-e when accelerating in 5th gear - only when car is nice and hot (gearbox temp measures 87c when it faults). They seem to think it needs another solenoid but I'm wondering if they've not properly rebuilt the gearbox? - since the last time it did this I have now developed a judder u can feel through the whole car (even in park) from 700-1700 rpm. Hoping you could shed some light before it goes back in for the 3rd rebuild in 2 weeks?

No, no special tool, may need a seal puller or something with a hook on it to get the seal out, but the new one should just go right in, just becareful hitting it in, try to do it even, hit it more on the edge so the top of the seal does not get damaged

Hey Gary, I have a question. I have one of these on a bench right now with a pump seal (o-ring) leaking. Is the pump removal and reassembly just as simple as unbolting, pulling out, then putting back in? ZF has a TSB stating the pump should never be removed for normal service, so I am afraid there is a reassembly procedure to get it back in. Thank you!

Hi, I have got a Jag 2.7 Diesel 2005, as I noticed stopping is not precise and the pedal was bit stiff, I took it to the mechanic he changed the break pads and the vacuum pump but still same? what should I do?

Please can you help? Love the video and very detailed. I have a noticeable intermittent gear shift problem . During hot weather+long drive+slow moving traffic+incline+harse acceleration, it has slipped twice and its happened intermittently and went into limp mode. Resets when ignition turned off and back on. Fault codes C & E ratio monitoring have been flagged on the OBD. Otherwise, it drives normally as though the fault has disappeared, but I know it needs attention sooner rather than later. Is this a valve body issue or the bushes in the gearbox that need overhauling. The problem hasn't surfaced for weeks. Any help would be appreciated. Thanks.

Hi Gary, I believe I have the same trans in my '03 745LI. The car will not go into any gear and obviously will not move at all. I haven't dove into diagnosing yet but i believe there may be a leak around the pan somewhere. If there is a leak, and the fluid is low, could that cause the car to not want to go into gear with the electronic shifter? Every time I attempt to put it into D or R, it automatically goes back into P and then I get an error from my iDrive system. Thanks for any help you may be able to give me! Love the videos!

Hi. I got my hands on a 2004 xkr portfolio with the 6hp26 that saw a bit of time under water!!! Water got into the trans and was still IN the trans when I got the car. Months had elapsed. So let me ask,,, is it true that the materials on the clutches are bonded with a water based adhesive??? How scared (besides horrified) should I be? Amazing video(s) btw... I've watched many of yours. I also have a 1990 XJS that I want to put a 700 transmission in and I watched your rebuild video to give myself an idea of whether or not it was something I could do. Still on the fence with that... Anyways,,, the innerdz (large hardware) of the 6hp26 don't look even as complicated as the 700r4. The valve body, not so much, scary as hell. Is the larger hardware, drums steels and clutches as "straight forward" as they seem? If I only wanted to exchange (if the water based adhesive is true) clutches. Doable?

Gary, Have a 2005 BMW 745LI with the 6hp26. Getting 5140 and 1720, no crank, no start. Pulled tranny changed bushings, put it back together. Fired up, then quit and then nothing. Figured the starter went. Replaced it still nothing. Replaced the SGM and programed it, new battery, Still nothing. Do you think the TCM is toasted? I can talk to it, but that end of the bus is down. Figured maybe central gateway was it. Thank you in advance

Hi Gary, new subscriber here. I have a 2008 BMW 528i. Do you know if I have this transmission? I had a transmission malfunction message, the transmission would downshift by itself to second gear and the only code they found at the shop was "no signal from crankshaft" so they replaced the crankshaft position sensor and the problem went away. That was about 10,000 miles ago and so far so good. The car now has 132,000 miles and I bought it with 100,000. I don't know if the fluid has ever been changed. Do you recommend changing it now?

I have BMW 530d with this ZF6HP26 with about 130K miles on it. I think that oil was newer changed :( . Now I am experiencing kick when coming to stop. To be precise, when I am going really slow and breaking really lightly, like when You want to be gentle and stop slowly without jerk I experience sudden kick. It feels like when trans. engages for a 0.5 second or so and tries to pull. It happens more when car is worm. Also when it is cold first shifts 1-2-3 are little harder, then no problem. Except this issues, I think that it shifts ok. I have in plan to buy Bridge seal, tube seals under mechatronic, oil, new oil pan, sleeve or connector and do oil change.

Gary Ferraro thank you Gary, I sent an email a few moments ago. I appreciate your willingness to help!

Hi, Gary. Thanks for a great and very informative video. I have a BMW 535d with the ZF 6HP26Z, same as in this video I believe. My problem is that the converter seems to slip. My engine is a "torque monster" with about 650 Nm @ 2000 rpm. I know this transmission has a 'warm-up program' and that the TC doesn't lock up before the gearbox gets up to temperature. My gearbox seems to stay in this mode most of the time.I'm describing it like that, just to tell you how I think it feels. I also have fluctuating revs when cold. If I am in 3'rd, 4'th, 5'th and 6'th gear and push the throttle - revs climb, but the speed isn't picking up as it should if the TC had lock-up. I asked a workshop what they thought the problem could be and they told me that the mechatronic most likely is worn out and needs to be sleeved + zip kit and that the bushings for the e-clutch most likely is worn out and leaking pressure. Cost of repair... hold your hat.... $5.100 to £5.700. Seems crazy expensive. I have talked to lots and lots of people with the same engine and transmission combination as me and they all have solved the problem after replacing the TC. What do you think the problem could be? I'm thinking of removing the transmission myself, install a zip kit, bridge seal, tube seals + a new converter (maybe bushings too if it is DIYable and new friction and steel plates for good measure) - do you think this would fix my problem? - would be much, much cheaper than leaving my car at the workshop. Thanks again for the great video!

read the last post but never made it to the page, not sure why. well, with no codes it hard to get direction, but it sounds like theres something going on possibly with the converter, while driving, did it ever feel like you were driving over railroad tracks even though you weren't? that would be a converter chatter. How many miles do you have on the car?

@Robert.K

Thanks for your reply. Revs are fluctuating about 200 rpm at light load going from 35 to 50 mph. I can see the needle on the rev counter jumping and hear the engine note change while it's fluctuating. To my knowing this is caused by the lock-up clutch engaging and disengaging as it is cured by replacing the TC. Many are replacing it with an uprated unit that's rated for more torque. Sussex Autos in the UK does these upgrades and lots of people I've talked to in England have had their torque converters sent to them for a rebuild with great success. I have a vibration that I believe comes from the transmission/tc, not like driving over railroad tracks, but it's a light vibration felt like it's coming from the middle of the car. I can feel it in the seat, but nothing in the steering wheel. Car has driven 114000 miles. Oil change / hot-flush, ZF pan and ZF lifeguard fluid was done 25000 miles ago. Oil looked good, not dark/burned. Pan was clean. The connector sleeve was also changed back then. Slipping and fluctuating revs were present before and after oil change.

well, certainly sound like a converter, there is a solenoid(i believe its EDS 4) that works the apply and release of the torque converter, this is all it does, you may want to change that as well, these solenoids have issues of becoming mechanically clogged. Greetings from New York.

@garyferraro We really appreciate these videos. Sometimes I get a mild clunking noise, pretty quiet accompanied by a minor (1/2 second) delay when accelerating after coasting/mildly decelerating. It feels almost as though the transmission is engaging late, like their's some give in the transmission or something. Is this normal behavior in the automatic zf6hp26 (for hyundai genesis 4.6 09, by the way)? Or should I be concerned about the transmission.

Gary, great video! I am new to transmissions and this helped tremendously! Thanks Ok, here is the reason why I came by this video. I have an issue with my transmission and maybe you can give me some direction on what to do. I have a 2007 BMW 530XI with the issues you described. First, it dropped from 6th to lower gears and the engine would rev up. Then I got the transmission faults. Now its doing it more and more, feels like a transmission clutch slip ( stator bearing ?). Car has 230,000 miles on it and it runs great with no body issues ( in fact body is in great condition). Do you recommend rebuilding the transmission or doing some low cost maintenance to maybe make it last another 40k miles? Also, how long do you think it will last like this? I live in the Chicago area and would gladly drive to have you service it lol. Curious, how much do you charge for a rebuild? Thanks

Hi Gary, I have an 2006 land rover discovery with a zf6hp26x. When car has warmed up I am experiencing revs fluctuating by about 1-200 rpms on a constant throttle at speeds between 30 and 70mph, more pronounced on an incline. There are no fault codes and everything else is fine. I am in the process of removing the gearbox, but am unsure of exactly where to find the problem. It seems like torque converter clutch problems, is this most likely to be the torque converter, 4,5 and 6 clutch, bushes, or valve body ? Hope you can help. John

Hi Gary, Thank you so much for taking your time to help me. My car has E-shift automatic and yes a park button. 2 weeks ago I started the car but a gear logo show on my dashboard and the screen said transmission malfunction, I tried to put it in gears (reverse, n, and drive) but it doesn't go into gear or anything it stays on Park but after about 20-30 minutes of idle I restart the car then the gear logo disappear and I was able to go in gears. Once the car goes into gears it drive very smooth like nothing happen but if I shut down the engine and let it rest for more than 30 minutes the gear logo will come back on and I wont be able to put in gear unless I let it idle for 20-30 minutes. Last week I installed new oil pan/filter and fluid then I started the car added more fluid but I was unable to put in reverse and drive but I did added about 2 more quarts when the car was on. After I added the fluid the car doesnt go into gear anymore even if I let it idle for an hour. Please any advise. Thank you.

I was able to get the sleeve out but I can't get the clamp to go back up (even with no sleeve in) I think I got the new sleeve in but I couldn't get the clamp to close either. Did I break the clamp beyond repair? Is it possible to replace it easily?

The clamp will not close if no sleeve is installed. Take the O-rings off the new sleeve and install them on the old sleeve, sometimes I can't get the new sleeves in either

Hi. I have same gearbox as you present in the video, soon after engine fires up i hear like a knocking noise, the output shaft that connects to the propshaft gets engaged and slightly moves then comes back to it.s normal position. It.s like a shock just after you start the engine. No error codes at all, also the gearbox change gears as it should. I.d appreciate if you could have a say about it. I.ve been told by someone it.s either the bush for the output shaft or a bearing inside the gearbox... thanks for the video

Hey Gary, I'm having a hard time taking out the sleeve seal. There's no room to take it out from the bottom. I took it out from the valve body but now its stuck in between the transmission and the body of the car. Seem like impossible to remove it. Can I just reuse it? I really want to replace it though. Please help. Thanks

Hey Gary, I tried to take the sleeve out but I couldn't and it still looks good so I decided to put it back. I did changed the valve body adapter seal. I checked to see if there's any leak on the sleeve but I didn't see anything. Now the car runs smooth just like new :). I saved $17000 yup the dealer quoted me $17000 for transmission and some error codes which didn't need to fix. Thank you so much for your help, your videos are really great.

Hi Gary, I have an issue with my ZF6HP26 (170000 km, Jaguar XJ6): Torque converter is surging, transmission is shifting very hard from 1-2 and a bid hard from 5-6, after I have installed the Sonnax ZIP Kit on my mechatronic. After doing this, all shifts had been hard, but got softener over each shift, but only 1-2 remains hard and 5-6 a bid hard. Before, 1-2 was bumpy and 2-3 failed sometimes and it shifted only at the second attempt with high rpm. I have already an exchange transmission here (198000 km, Jaguar S-Type). So my question is, how could it be, that shifting from 1-2 is very hard, which clutch could be defective and why is downshifting 3-2-1 still clunky and a bid hard? Thanks for your effort!

@@GaryFerraro I have exchanged the valve body now and problems with shifting are all done. So it looks like some of the pistons have been worn out and the clutches and brakes are still fine. Only the torque converter is still surging or cycling in rpm, but not as much as before. Is it a matter of the clutch inside of the torque converter? And how does it come?

Dear Gary, I am working on a project on automatic transmission development for two wheelers and Im in the initial phase of it. I took ZF6HP26 as a base and I am stuck with dimensions of planetary gears and torque converter for the modelling and simulation purpose. If u can help me bit with it i will be greatly thankful.

Problems in the higher gears 4th,5th and 6th is very common, this is usually due to a worn rear stator bushing, when the bushing wears out, it leaks E clutch oil causing problems in the higher gears.

Hello Gary. I would like to thank you for your videos and guidance you gave me a few weeks back in rebuilding my gearbox. I have successfully replaced the bushings, frictions, seals and solenoids in mechatronic. Also I have rebuild the valve body using the zip kit. This wouldn't have happened without your videos! Thank you. I haven't looked at the torque converter as my tranny was free of any contaminants /metal failings so I thought it's good to go. The symptoms are gone about 80%. The tranny shifts very smooth and plenty of power but high gears are still giving an issue. The tranny doesn't go into limp mode like before but still throws a code: 4F4C. I would like to ask you for advice and I will try to explain the issue with as much detail as I can. It only happens in 5th and 6th gears: 1. Light acceleration have no symptoms - works perfectly. 2. Moderate to Hard acceleration will cause a hesitation before it picks up speed - engine will revv and then immediately drop and eventually will "catch" and then go. It feels as if the clutches are slipping or lack of oil pressure, there are no noises, vibrations or whacks when this happens. After the engine revs, drops the revs and gearbox stabilizes, then the car pulls like a train, no more slips, works as it should. That is until I slow down a little, change a few gears and then if I moderate or hard accelerate it happens again. Sorry for the long text, I don't know how to write short ones haha. Hope you have a good and easy day sir! Thanks Ciprian

Can you tell me the definition of the code your getting, just to confirm, you changed the rear stator bushing? Do you have a scan tool to reset shift adapts?

@ciprianM01

4F4C - Symptom gear check. I have changed some bushings in the tranny but not the rear stator bushing as I didn't notice wear. Thinking about it now, maybe I should have changed it. I have the Snap-On Modis Ultra diag tool and I have resetted adaptation. There was indeed some option for mechatronic adaptation and I also think for gear ratio, I can check in the morning for the correct names. There could be a possibility that I haven't reset adaptation fully.

@GaryFerraro

7 жыл бұрын

If there are codes present in engine or trans, the adaption may not work. The rear stator is a very common issue, when it wears, it allows E clutch oil to escape and slip in the higher gears.

have a 05 545i, 1-3 gears no problem bit 4th slips and goes directly to safe mode. have switched 4th and 5th solenoids and still same issue.
