I have a 1998 Oldsmobile Bravada Smarttrack
I have scanned through these forums and (finally joined
)have done some recommended fixes - but one problem is still lingering.
Here is what happened:
I took the Bravada off roading - and when i got out of the mud track - The suv would not shift past 2nd gear. It would die on me sporadically. Sometimes it went all the way to OD, but then would not switch back to 1, 2 or 3 - and sometimes it would only switch from 1 to 2. I checked the fuse box in the engine bay and found that the 20AMP ATC fuse was blown off. I replaced it - and then drove home limping - with several lights on - ABS, Check Engine, Brake, Service AWD. The speedometer would fluctuate - down all teh way to 0 and then back up to 60 etc...
When I got home I looked at the forums here - and saw that people thought it could be the actuator under the battery - I took the battery out but could not find an actuator. Does my model year not have one?
I then scanned the computer for codes - and found one that said that the vehicle speed sensor A was erratic, also that the EBCM is faulty. Went to the junk yard and pulled an EBCM from another 98 bravada, popped it in - and that took care of the EBCM problem. I then also replaced the vehicle speed sensor in the tail end of the transfer case.
Took it for a 5 min drive - and saw that the service AWD light came on intermittently. No codes were found with my OBD2 and ABS scanner.
So - now what do I do? I do not know what the problem could be. Should I just replace the TCCM in the passenger side kick panel - or replace the transfer case motor?
Does anyone know how to get that skid plate that is under the transfer case off? Please help - I need this truck working. Wife is mad, because this is her truck. I am using our other Buick to get to work...
