I am new to the forum, I guess I will use this thread as my intro!

I thought I had a nice piece of info I could add to the community.

Name is Nathan, I am owner of Atlas Coatings & Construction out of KC. I also own Apollo Powder Coating, and soon to be a few other complementing companies. I strive to do the best, be the best without the ego.. just want to be a master at all I touch. I don't think I will ever be able to truly master women.. they are a bit tricky and always change!!

Recently I rebuilt my 4L60E transmission, only I morphed it into a built 4L65E.

List of parts includes:
kolene steels & Alto clutches, purple accumulator springs, pinless accumulators, transgo thicker seperator plate, billet servos (superior transmission), sonnax pressure boost valve, Wider band, has the 65E upgrade (all rollerized internal thrust bearings replace the thrust bushings, 5 pinion gears, wider reverse drum, beast shell) Royal Purple trans fluid, new filter, all gaskets replaced, and Sonnax Torrin synthetic 1/4 checkballs.

I already have the transmission rebuilt. I made a promotional video for the actual rebuild video I have not started on. I will update this thread, I have 100's of gigs of video and pictures that are going to go into this video.

It was tough to pull off rebuilding the transmission when I could only ask a buddy of mine who owns a transmission shop here and there about some different issues.. I didn't bug him out of his "office hours".. but by calling manufacturers of the components and the boxwrench rebuild video... I pieced it all together.

She runs like a raped ape now.

Okay without further delay.. the promo video (I am not going to "charge" for the video, just want you to know it is coming out ) BTW watch in 1080P!

An OEM 4L65E had different heat treat method on the shafts, indicated by the different color of the input shaft. At least that is specs GM put out in the day on the 4L65E

Yep. it is the reaction shaft, it is also machined with a shoulder for a thrust bearing INSTEAD of a thrust bushing. The rear drum is the same way. I have pictures, I will post when I can. Believe me.. I built it right

the 60E has thrust BUSHINGS not the rollerized thrust bearings that are unique to the 65E.

That would be incorrect to some degree. EARLY 60E trans had thrust washers.

GM installed torrington bearings on the 60E as the trans design was updated. They also changed the design of the torrington bearing on the input planetary unit and matching shaft.

As I said earlier, the 65E had better heat treat on input shaft and output shaft per a GM spec sheet I read.

As for the torrington bearing on the reverse input drum.. I performed that modification years ago when nobody did it.

On average I built 200 - 220 4L60 units a year for many years.. I've seen a few things.

yeah, in just 2 different transmission there were quite a bit of difference, and depending on who was working on it.. they will add their own "opinions" on the build

depending on who you ask seems you always get a different answer. My information comes from both atsm sources and my buddy and his dad that own a trans shop here locally.

These are fun transmissions no?! I want to start to rebuild them.

Let me ask you.. do you put back the little pressure plate springs around the inside or did/do you leave them out? The 99' trans I rebuilt didn't have them, but the 01 did.. lol

Here are photos of different 65E parts.. notice 5 pinion planet. Notice that dang output shaft, that is where failures happen often with higher horsepower. Those dang pesky lube holes in the shaft seem to weaken it.

The 4 pinion planets in the 4L60 trans are fairly durable, usually failure is related to loss of lube or high mileage.



Gee... is that a beast drive shell there?



I have many more photos, not just 4L60E / 4L65E / 4L70E stuff ..

Lets see, you ask about the aux release springs in the 3-4 clutch if I understand your question .. I reuse those in many applications, although I use new springs from Sonnax and I modify the retainers for the springs.

Many builders say to leave these aux springs out, I have built the trans both ways. Depends on application of the trans, street or drag race or off road race.

I rebuilt one 4L60E, using TCI's best kit. Mine turned out very well, as did a 700R-4 I tried with a now-discontinued kit from B&M. But even after these 2 successes, I'd still not be comfortable with trying this until I had a lot more experience. Less intimidating to just tackle the 4L80E swap, despite it having ratios I don't care for.

Crosley your nuts man! Hey I am running out the door, thanks for the replies! I am just happy to have anyone to talk about it.. I say auto trans.. everyone's ears melt off! LOL

I will look over everything and get back to you.. probably LATE tonight.

Stay cool guys
