Thank you, Kevin!

So I recently rebuilt someone else’s “performance” 4L60e. The customer stated that after the truck the unit was installed in sat for a few days it would not go into reverse. Let it warm up to near operating temperature and it would then engage as well as engage every time after as long as it didn’t sit for more than a few days. I took it apart and found damage to the reverse input drum that was causing a sealing issue w the Teflon seals. I put a new AC Delco reverse input drum and a new stator shaft (it and the bushings for the RI were all beat up). Aaaaaanyway the transmission was set up pretty much as the one you have outlined. I would say 95% so, but I found something interesting that I had not seen before. The input shaft and the stator shaft were from a later model meaning an exciter on the input shaft and a pocket on the stator for an ISS even though it was not wired or otherwise utilized. Finally to my point…..there was a very fat plastic bushing between the reverse input drum and the back of the stator! Probably twice or even close to three times as thick as a factory piece. I have read that there can be upwards of 0.225 clearance between the two in a factory setting and that it is normal and shouldn’t be a cause for concern. It does however seem that tightening that clearance up (if it is in fact that much) might be beneficial in a high RPM situation. I don’t know who makes it but I have been on the lookout.

I have also seen availability of a reverse input drum that is machined to accommodate a bushing that protrudes slightly to center and accept a Torrington bearing between the drum and stator! Thereby FULLY rollerizing the internals

@nickstransmissions

Hi Ross, yep you can rollerize the front thrust using a machined reverse input drum or you can use a bushing from a 200-4R that protrudes slightly above the surface of the direct drum, which will allow you to add a bearing there as well. I believe it's a TH350 pump thrust bearing and you orientate it so the black side of the bearing faces the pump to avoid exposing the bushing to the part of the bearing that rotates with the drum.

Awesome. Thanks for the video!

Hey Nick, I installed the 4l65e back in to my H2 Hummer! Runs great expect at 45 to 50 MPH the needle on the tachometer studders like jumps up and down. I have to give it some more gas to power through. Why do you think that is happening? Thx!

@nickstransmissions

Erratic speedometer behavior at those speeds is likely vehicle speed sensor/wiring to the speed sensor - check the wiring; if good, install a new VSS. If your engine itself is stumbling or hesitating at those speeds and beyond, check fuel delivery systems for weakness (pump, FP regulator, etc). Honestly, could be any number of things with or beyond the transmission. Plug a scan tool capable of rendering live data and bring up engine and transmission data streams and make note of what you see in the data when you hit those speeds...Perhaps have a helper watch the scanner while you drive or vise versa.

Nick thanks for another video great job! If you were building a GM street/strip transmission 350/400/700 would you choose Raybestos Red frictions over Alto Reds?

@nickstransmissions

Жыл бұрын

Thank you, Bee Gee...I would as I generally don't use alto reds too often. Borg Warner or Alto high energy frictions are also a good choice for street/strip.

Another great video. I like your no nonsense approach to this type of work. I have a quick question. I know you have said before to leave the 3-4 clutch springs out if not doing a performance build. Is it okay to leave them out if not doing a performance build and using the Transgo 7-CS spring kit?

@nickstransmissions

Жыл бұрын

Thanks, Jay...It's up to you if you want to include or leave them out but my general guidance is that if you set the clutch clearance down below .035", keep them in. Otherwise you can leave them out. That applies to any type of build when it comes to the 700R4 or 4L60E.

Got a dumb question....I have a machined empty front cover. Turned mine in to a machine shop as a core a month ago. What's the best way to find out what boost valve length is needed?

@nickstransmissions

You can purchase a 2nd design boost valve/sleeve kit along with the accompanying spacer that Sonnax sells that allows you to install that 2nd design kit into an earlier pump cover that otherwise came with a first design boost valve/sleeve from the factory. I believe the change over was in either mid-2006 or 2007...

No, it would be fine and the vehicle mentioned in the video is making 650hp at the crank. If that was 650 hp at the wheels, I'd opt for a Sonnax billet steel front planetary gear set as well.

When you install a built transmission like this what needs to be done to the computer. Does it need to be tuned?

@nickstransmissions

Жыл бұрын

Computer will definitely need to be tuned for the engine; depending upon how the vehicle is being used, it may be prudent (or even necessary) to apply some tuning to the transmission as well.

Thanks for watching, Corey! For case improvements I'd install a an 903 Corvette servo, Sonnax smart shell, max pack in the 3-4 clutch and perhaps a front and rear 5-pinion 4L65E planetary carriers set. For hydraulic improvements, pretty much the same stuff I do for most of these units, but exactly what I would do would largely depend on how the vehicle was going to be used (i.e. just daily driver, street strip, racing, heavy duty towing/hauling, etc) and converter stall.

The trailblazers had a TC stall of around 2000-2200 or so. I'd download Transgo's instructions for their HD2 shift kit off their website and follow their guidance for separator plate feed hole sizes however DO NOT drill the AFL balance or TCC regulator feed holes at the bottom left area of the spacer plate unless you actually install their shift kit, including the white inner AFL spring and blue TCC regulator spring in the valve body...If you're not planning to install their kit, drill the feed holes for the 1-2 shift .076-.080 if using a corvette servo, 2-3 shift, 2-3 accumulator (aka band release) and 3-4 shift to .093. If you want firmer apply in manual low and reverse, drill the L/R feed to .080-.086 and remove the low reverse check ball. Otherwise, keep it in and leave the feed hole alone. If the 4th gear shift is too soft, simply block off the 4th accumulator feed in the case using a cup plug and leave the spring, piston and pin out of the 4th gear accumulator bore.

Hi Steve, I actually haven't been into Allisons just yet but may in the fall...Those transmissions are generally very resilient and don't need overhaul all that often and when they do, most will seek a good used unit for 1-2 grand vs shelling out the 5k+ for an overhaul...There's a video on YT called something like 'The best Allison 1000 Rebuild on KZread'...I haven't watched it but the thumbnail looks neat, haha. That's the only one I'm aware of off the top of my head.

Sonnax six-pinion front planet? 3-4 Z-pack?

@nickstransmissions

8 ай бұрын

Avoid the Zpack, it's not my favorite for anything high performance as the individual plates are too thin and don't withstand heat very well from what I've seen...Run an Alto or Raybestos Max pack using Alto Reds or Kevlar-impregnated HEs, Raybestos Blues, GPZ or Stage Ones w/Kolene coated steels or Borg Warner 4L65E clutch pack with lindered steels (same as Kolene) instead. Six pinion planets are great for racing as they narrow the stupidly wide ratio between 1st and 2nd gear but if you're not racing (or the primary use is street driving) they're not mandatory. Please give a thumbs up if my info is helpful; if not, please let me know what can be done differently. TIA
