Really bad slip in reverse on 4EAT

[Splinter]

If you're on any kind of an incline, you can't back up at all. On flat ground, you have to rev it pretty high to get it to move.

Is the tranny just toast or is there something I can do?

[legacy4ever]

your clutch packs are probably toast. rebuild kit is an answer.

All the other gears work perfectly tho

got the same issue 2 years ago: all forward gears but no reverse. mine had burnt clutch packs.

you can always take her to the shop and let them check the line pressure.

Oh really?

Hmm..

Time for a 5 speed swap I guess

Do a stall test, time lag test, and line pressure test. If everything comes up bad just get a new tranny, if its only the reverse clutch, and low & rev brake then just replace those clutches and be done with it.

Though considering it's probably 150 ish for a set of clutches for both new and you can probably get an aftermarket full rebuild kit for like 200-250 it'd probably be more worthwhile to go that route and replace all the clutches you go through to get to the low & rev brake.

BTW rebuilding an auto is HELLA easy. People just make it out to be hard because they don't undestand it and think that all the moving parts are like rocket science or something.

95% of the work in rebuilding a tranny is getting the tranny out of the car....

and if Im going to do that, I might as well replace it with a 5-speed, seeing as I have a few of them kicking around.

yea i just had the same problem in my N/A. i replaced it with my turbo tranny. when i tore it apart the clutch packs were shot
