1994 Isuzu Trooper 6 cyl Four Wheel Drive Automatic 130000 miles
My transmission is not shifting automatically. The check trans light is flashing as well. It will shift If I shift it into low gear then up shift as I accelerate. If I don't do this it seams like it is trying to take off in 3rd gear and accelerates very slow.
OK it is a 3.2L SOHC enginge. Not sure if it is the S or LS but the VIN is JACDH58V7R7918645. It does not have an OBD II port to check for codes. It only has a three terminal port hanging from under the dash.
When I ground the two outside terminals on the port together as it describes in the not so helpful Haynes manual, I do not get any fault codes. It just keeps flashing the # 12 system acknowledgment code. The check engine light has not lit up yet but I have a check trans warning light that keeps flashing. I'm sure this is trying to tell me what the problem is but I can't find any info on what this warning lite is for.
I did drive it on the highway today and found out that it is not shifting into O/D either.
Thanks for your quick response in trying to answer my question. Let me know if I can give you any more info that could help with trouble shooting.
have the same problem?
