Beefing up a 4L60E?
 

For a '95 Z28. What all exactly would I upgrade to beef the transmission up so it'll last awhile. My car is stock, btw.

How do you know if you have a 4l60e transmission? I have a 97 z28 that is an automatic. Does this come with a 4l60e? The shifter goes down to 2, then d, and then d, then N, then R, then P. Please Help?

You have 2.73 gears too.

The most common point of failure is the aluminum drum. Some fail even on a totally stock car. The 4L60E is in many ways an inferior transmission for hi-performance applications but they can be built to handle about 750rwhp good for mid 10's in the 1/4. I'm looking for some single digit times so I'm looking at a 2004R or a TH400 when the time comes.

Yeah, my 3-4 clutches aren't engaging at all. I put it in D and OD and 2nd is as far as I can go.

not 100% right the 4l60 can be built very good you just have to know the right shops like rossler and bonnat's trans they put a c4 in the mid 8's with over 400 passes i just got my trans back from them

This must be a very recent development. I'm glad to hear it but do they also make a reliable trans brake for it? Last I heard they weren't holding up.

"trans brake" i dont know they call me the foot brake kid lol
