Re: 2001 Isuzu Trooper Transmission NIGHTMARE "Thread 2"

A common cause of "transmission problems" on Troopers w/the 4L30E is actually the switch mounted on the shifter linkage.
It tells the tranny ECM what gear is selected, and when they go bad you will get all kinds of shifting problems. One clue this is the problem is if the gear indicator lights on the dash are wrong or erratic.
GM vehicles withe the 4L60E tranny have a similar switch and similar problems.

I had to replace the one on my 2000 Trooper last spring. Takes about 1/2 hour to do.
