Never heard of em. You can upgrade your existing 4l60e with parts from PATC:
http://www.transmissioncenter.net/4l60e.htm . I just designed my upgrade and took the parts to a reputable shop in town that regularly builds racing trannys and done deal! I did have some issues I won't get into on here, but if you want to read about it just search my threads.

Alot of guys favor the 60e upgrade over swapping to the 80e due to the gearing differences between the two.

true, or have it built into a 65e.

built to a 65E gets my vote. probably wont have to worry about it again for as long as you have the truck. done correctly that is.

Not really sure I understand what you are saying? You are building a better tranny than the 4l65e if you upgrade with all the right parts. 5-pinion planetaries (dont forget front AND rear!), high perf billet servos, hardened input shaft, high perf clutch packs etcetc. My thread has a comprehensive list of everything I did, I didn't miss much

Not to mention if you take it to a "reputable" shop, they should have some really good experience rebuilding these types of trannys. They are immensely popular in the street racing crowd. They will likely adjust some of the valve body as part of the rebuild. I can't remember exactly but I think they bore it out to increase pressure or fluid maybe? Someone help me out here...

My fave part was the "unbreakable Pump Ring Set"

Do they REALLY make an unbreakable part...I'm sure Jeff could break it

In 2001 an updated version, the 4L65-E, was introduced. Five-pinion planetaries, along with a strength-improved output shaft, were improved to withstand the 300+ ft·lb (over 400 N·m) of torque of the 6.0 Vortec engine.

So a good tranny shop could update to 5 planetaries and input shaft and pretty much have a 65e.

True, 80e gearing is:

Gear Ratios are:

First Gear - 2.48 to 1.00
Second Gear - 1.48 to 1.00
Third Gear - 1.00 to 1.00
Reverse - 2.07 to 1.00


and 60e is:

First - 3.059:1.0
Second - 1.625:1.0
Third - 1.000:1.0
Fourth - 0.696:1.0
Reverse - 2.294:1.0

This is the one that is being built to be put in mine.


i would be very careful with PATC

I bought the Wake Up Kit, their version of the shift kit, and the reason I am buying a new Transmission from the posted link.

I have never heard anyone say anything GREAT about their built transmissions? I just used the site to buy some of the parts cheaper than I could get them for and they have all the pictures and some explanations. I would highly recommend using their site to reference parts/prices.

I guess that is what I am saying...as far as a reference, I guess you'll be cool...but like I said I purchased the 4L60e WAKE UP KIT and some more parts accumulator....Super Servo...etc. And my Transmission looked like a grenade went off in it! As to why I am now purchasing a new Transmission from finishline.
