Max power on 4L65E
Max power on 4L65E Just wanted to know what the most power some of you guys are running on your 4L60/65E trannys and for how long? Ive been running 450rwhp for around 3+months and I had to firm up the pressure on the valve body for more positive shifts. Other than that it running good. Just wondering how long it will last.
No ones answering because its a loaded question requiring a crystal ball , We have units over the 600 rwhp range running over a year on our level 2 and 3 with 100s of track passes , But then there are some stock trans running high power and holding an some that don't make it past bolt ons. As for the 60/65e the primary difference is the addition of five pinion planets and additional clutch in the 3-4 set. Is it alot stronger than a 60E I would say no IMO a little but certainly no where near as strong as a properly built 60e or 65e . I know this does not tell you anything really but is some commentary. I didn't reply before because you were asking people who had run a stock 65e and I cant say that I have all the units I have ever run were built units in either type.

Patience there, guy.
My stock 4L65E in my '05 GTO with a stalled 2800 3 disc vig converter worked great with just headers and catback. However, when I put a procharger on and started pushing 540+ to the wheels, it would not take the 2-3 shift under WOT, and ultimately the 3-4 clutch pack blew (within a couple days).
