Question about 1995 Isuzu Trooper
1995 Isuzu Trooper v6 180k miles. Veh has been running fine - started up drove well yesterday, then Last night Start up & drive 30 yards and "Check Transmission" light is flashing like it's the end of the world. would not shift properly. I did not try and push it - 20 mph at the most. felt like it kept down shifting. Never did really slip, just not hitting gears properly. Fluid is good - Full and changed every 60 - 70k miles. Acts like something electrical - possibly harness or plug came loose? How can i pull the trouble codes to see whats up?
I had the same exact problem. look under the vehicle and find the shift control module. it is bolted on the side of the trans. check to see if it is loose. if so then it is misaligned and needs adjustment. for that you will need a 9/16 wrench and a 3/32 punch or drill bit. line up the slots, tighten down, shift through gears and your good to go.

Ya sounds like the electric shift solenoid. Problem with electrical. Will not give you a warning. Will go bad in a heartbeat. You can try unhooking plug that gos into the trans and spray electrical cleaner on it. plug back in. Wiggle some wires and maybe find one loose or broken wire or connection and hope for the best. But its probably the tranny with that many miles. Go to Advance Auto Parts they usually scan your car for free for codes. Good luck

Tips for a great answer:
engine and the automatic transmission in this vehicle are computer
controlled and in most cases when a fault occurs a fault code is
stored in the memory of the computer control module. There are
exception to this, such as the Mass Airflow Meter and fuel pressure
problems. What must be done is to have all the basic testing done
such as a scan of the system for fault codes as well as a check with
a live data scanner tool for engine functions that are not within
range of normal, a trained technician is required to know what is
correct and what isn't, then based on careful diagnostics done from
a factory repair manual the correct part is replaced or the wiring
repaired or the computer replaced (known as the PCM), which is very
rarely the problem. Other basic checks must be done as well such as
mechanical problems with the engine as well as engine state of tune
and mileage on the engine. The transmission can have mechanical
issues as well such as no gear engagement at all or a failed pump or
other pressure related problems.
