there is no s light on a 92, only on the 90-91 years, the trans control unit is under the dash on the drivers side, maybe if your lucky you may have a friend with a 92-93 tcu to try. When my tranny went out on my 92 the d-4 light did not start flashing., a trans change out used to be 5-6 hours, I did mine at home without a lift in a little more than 5 hours.

 

Even though you have no D4 light flash, you could still have some TCU code/s stored. Some codes don't cause the D4 to flash. This is best way to diagnose your problem.

good luck

 

Wow! Stupid question- was it difficult? Does it just 'bolt on'?
For reference, the most complicated thing I've done on my caris replace the valve cover gasket I did a little mechanical work on a boat motor; diagnose/replace ECU, compression test, lower unit oil change, etc.
I'm good with electronics but I dont have a lot of mechanical experience.

 

OK I found the Haynes manual and read the procedure.

I located the computer diagnostic connection and jumpered it with a wire. I then put the ignition on ON and watched the check engine light. It stayed on- solid. I pulled the wire out and the light went out. I assume this means that (1) I entered the code mode correctly and (2) there were no codes.

The car has been sitting a while and the battery was dead (I jumped it). Unfortunately I think this means that any codes present were erased. Is this true?

Thanks

 

Yes, a dead battery would reset the ECU.

good luck
