My Trooper II does not start off on first gear. My mechanic changed the selector swith and then rebuilt the transission, to no avail. He now says its the TCM. Can't seem to find this part anywhere. Any suggestions? Does this seem like the answer to my problem?:frown:

Forgot to mention that my Trooper II is a 1991, 6-cyl.

what is the tcm?

New: buy it from St. Charles isuzu.

used find a pick and pull in your area: www.car-parts.com

:banghead: Ive got the same problem. The TCM is located under the compartment pan in your center console. A couple screws and unplug three connectors and its in your hand. Be sure to disconect the battery Neg before you start!

isn't it the ecu that is under the center console and the tcm that is under the dash?
