You are very well spoken and smart. Thank you.

Ok, now that finally explains it clearly! Thanks!

Another incredibly informative video, thank you!! You are peeling back the veil of mystery over torque converters, and that is very much appreciated.

Excellent video. Lock-up well explained.

Very well explained, thank you.

You got a sub and a like out of me. Great information without the BS marketing! I’m in the research stage of preparing to rebuild my own 4L80E in my 94 Chevy truck. Going to keep it running for years and will eventually need to rebuild the trans. I’ll be looking into your products for sure. Thanks!

Great video!! For bracket racing, would eliminating lockup on an oem low hp vehicle, eliminate a possible variable?

Has the race lock up video been made? I’m not seeing it and would love to watch it.

I have a 2,800 stall in my Art Carr 200-4r behind 502 with HD solenoid and manual switch which will lock it on the freeway, but when I switch it off on offramp, it doesn't disengage until several surges and drop below 40mph. I may need to get an aftermarket TC.

I have a question, only info I've been able to find is on forums which can sometimes be questionable info. Basically, the cam I've got my eye on recommends a 2600-2800 stall speed. Now I've been told by almost everyone I ask that your highway cruising rpm should be higher then your stall speed BUT I've also been told that a good lockup converter will compensate for it and be fine to run in a street/strip/daily driver combo. So are they ok to run that way and not run too hot or limit the converter life? Cruising RPM would be around 2000-2200 BTW if that's important. Apologies for the lengthy question.

thanks

Just cleared up the clutch apply mystery, I had it backwards. I'm still not sure if I will use lockup or not when I change over to 700r4 but hopefully I get more info on options.

Happy to answer any additional questions you may have. We offer lock-up and non-lock-up options both in our 700R-4 transmissions, although lock-up comes standard.

Great stuff. I have an RPM built 4l60e tranny that I have dialed in for the apply and release. It was perfect until a shop rebuilt the engine. After recieving the car back, the clutch will unlock when it shouldn't on the highway at say 4th gear at 70MPH when the load decreases or I ease up on the throttle. Could something have been damaged?

You must do a lot of business in the middle east and India since you sell such a wide variety of turbans.

hey 1990 k5 blazer with the 700r4 i converted from tbi to carb so i dont have the computer for lock up anymore...so i hook a toggle switch up with the 3 wires from my pig tail plug do i leave my switch on at all times or will i mess up something if i dont shut it off when im at a low soeed...i appreciate it

Hello, saw your video on lock up converters, I have a 1955 Chevy truck 265 engine with a 700R trans. I have a B&M dial box controller. What would be the best speed to dial the knob on the box to lock out the converter. Right now I’m setting the dial at about 40mph when the green light on the box comes on meaning the converter is locked up, would this be correct? Any info would be appreciated. Thanks Len

Great , Can you tell me time of lock clutch operating, i mean always or high engine speed , gear changing time or high vehicle speed time

So will putting a lock up switch on my 7.5l f250 make a better pulling rig out of it and we'll funner to drive?

You make one for the 4t65e?

I have a 37 foot rv with a tag axle, 4l80e powered by a gas 454 tbi, dual 2.5 hedders. I will be getting the transmission rebuilt soon. Since I will be towing with my 17k RV will I need the triple disc XTM converter? Will it tear up my transmission? Or should a just settle with the XTM single disc converter. When I call into Hughes Performance one technician says go with the single XTM single disc because the triple disc is for a deseil engine which is high torque, and the other technician says go with the 25Blxtm that it will not tear up the transmission. So, for once and for all, what is the verdict? Thanks.

@Hughes performance, I have a 4 speed automatic transmission and I notice lock-up of TCC happens at 40 mph on the overdrive gear. I do cruising speed in the city at less than this and it causes poor fuel efficiency. I would like to make a manual switch for the TCC that i can lock it at lower gears as long as it is past stall speed. . . Is there any problems with doing this? Is shifting from 3rd to 4th gear alright while TCC is locked up?

just a guess. sounds like someone hooked up the 3 gear pressure switch into the tcc. if you have a 4 gear external port outside your tranny case. hook up a pressure gauge n run it inside the cab. watch the pressure value as the vehical shifts into 4th. on the freeway at say 65 mph see what the value is. then buy a pressure switch closest to that. thats when it will lock up for you. more work for sure. better outcome. just sayin.. larry

I always thought that it is the line pressure coming from the solenoid and valve body that engages lockup clutch in my oem torque converter but obviously i was wrong. Great video series very educational i love it. Do you guys do any ZF transmission parts or torque converters ?

@HughesPerformance

We can build a ZF torque converter for higher stall speeds and can also incorporate some features to increase the converter strength. We just need your converter core to build.

I could see using a lock up for the 1/4 mile but I'm not convinced you have enough time in the 1/8 to take advantage of that feature ? Am I wrong ???

Will a failed lockup feature on a 1982 Corvette, 700r4, that stalls the car when shifting be resolved with a better [Hughes] converter?

Will a high stall(2500) converter lock up lock up below the stall speed. In top gear

Yes sir, any converter with an active stator is capable of achieving a reasonably efficient part throttle coupling when properly matched to the appropriate engine modifications, axle ratio, and tire sizing.

Will a 1982 Chevy GM th400 torque converter fit a 1991 700r4 trans. in that same 1982 Chevy ? Thanks...Liked Subscribed !

Not all apply strategys are the same. At 8:50 you say that the clutch is not applied by pressure but rather by natural internal forces. The stock 4L60E does indeed have apply oil supplied from the pump and between the hub shaft and the stator shaft.

Im told i can get my tc to.lok up in 3rd.. 700r4 in my 87 k10......cut power wire to sol. And then cut the other two wires on the 4 pin ...splice them together......this shiuld lok up od...but not sure if i loks up 3rd.....can you confirm?? Thx tomk ret fdny

I wouldn't recommend spending that kind of money on an A999. You're far better off with a 727 or adapting a TH400.

I keep trying to think of a best of both worlds design combining the advantages of an auto with the advantages of a manual. As a daily I can't drive auto cars because they are so boring I start to stop paying attention and I kinda go into a brain fog, sometimes falling asleep (happened twice, second time I got in a crash) which is why I drive manuals now. But I understand the advantages to an auto for racing. I used to argue against that for a long time but I'm drag racing an auto wins hands down. I'm on the fence for any other racing. I still can't think of anything where you have complete mechanical control over the trans but can shift immediately with an auto. So I'm still sticking to manual vehicles. Oh, an auto can't bump start yet. Yes I've utilized this many times. For me, the perfect setup would be 1- manual clutch control. 2- manual gear control (no shifting when you don't want to). 3- instant gear changes. And that's it. The trick is instant gear changes while having manual clutch control. Big advantage to a torque converter is stop and go traffic on the highway. So it's a constant back and forth between the two for me.

Does the 4l60e only lockup in OD at freeway speeds?

@heathcarr1105

4 ай бұрын

It will lock in 3rd as well as long as its above the speed that the computer is telling it to lock. In D it is usually after its shifted into 4th tho. You generally have to have it manually in 3rd for it to lock up because of the speeds its programmed to shift at.

We can rebuild your OEM Audi torque converter and alter the stall speed characteristics if you like.

Haven’t watched yet but when I think lock out, my Overdrive coming to a stop shakes the car violently and slams into 1st gear.. if it’s in (D)rive you will never notice the downshift… 1988 mustang 5.0 AOD (2500) stall all I lnow

Why do so many smaller displacement engines making well over 1,000HP have a recommendation to not run a Lock Up Converter? I've heard of guys in the 2JZ world that engage the lockup 400rpm too soon and it can completely grenade a Billet Block. Why is that? how can just engaging a Lockup a few hundred RPM too soon send Billet Rods through a solid Billet Block? I've also heard the same in the Chevy LS world. So why?

What about 4l60
