I have a 2001 Trooper that I purchased about two months ago. It has 96,895 miles on it and has had two previous owners. Is it common in Troopers to have tranny problems already?:screwy:

I have a 2001 and had to have the transmission rebuilt at 65,000 last summer. There was something loose in the transmission banging around inside, something fell apart in there and I needed a full rebuild. Just recently it started slipping again. I will take it back to the transmisison garage soon. By the way, the transmission is sealed and is supposed to be maintainence free, it is sourced from BMW.

Typically it is common for Isuzu trannies to die with 80k-100k when the tranny fluid is never changed.

What is the tranny fluid history on your truck?

There are some other issues that may cause tranny issues:

Dirty range selector
Low tranny fluid
Weak Alt or battery (isuzu trannies do weird things with wacky voltageO.

These Isuzu tranny's ARE in fact the GM 4L30-E transmission, and they were USED in BMW's, but they are not a BMW design.

Also, they are NOT maintenance free/totally sealed transmissions; they in fact do require fluid changes every 30k AT MOST!

I currently have 174k carefree miles on my original tranny on a hard worked Rodeo, this truck gets fluid changes every 15-20k, with twice as late as 30k, but have never gone over 30k without a change out.
