Have a 95 Z28 and had th 4l60e rebuilt 7000 miles ago and now it is slipping in drive and when cold somtimes want shift out of 2nd any help would be great.

 

Man that sucks
Did you get a warranty?
If so, take it back, tell them to fix it RIGHT this time.
If not, get a high performance rebuild with stall, cooler everything else at the same time, not that much extra money, totally worth it. Someone on here should be able to post a link, I forgot them.

Unless you're an auto tranny guru, digging inside the tranny isn't recommended, I definitely wouldn't do it, not after seeing some of those pictures in the magazines of what the inside of a 4l60e looks like, I'd need some more experience first. When the tranny starts slipping it necessitates a rebuild- just make sure it's the tranny and not something else. When my opti started going I thought it was the tranny screwing up at first...

 

I've never done tranny work but have seen guys at the shop working on them. It's a real teadious process because there's so much crap in there. Easy to make a mistake. I know this because I saw them screw up a guys 89 z28.

did you get a warranty? Most places give a 12k warranty.

 

when i rebuilt my th350 it ran great......al long as you didnt try to spin the motor past 4500 lol. it just wouldnt let you rev it that high. no idea why.

 

Thanks for the reply. It came with 12k waranty and I am taking it back to them in the morning. I went to the track last wednesday night and the next morning didnt want to shift out of 2nd and after warming up it would slip into drive. Talk about being pissed.

 

If you even hint about taking the car to the track your warranty is toast...
