ECM question
I've recently purchased a 92 convertible roller (no engine, no trans, no ecm), the car was originally equipped with LT1 and 6-speed. I also purchased a 92 LT1 motor and automatic trans that were removed from a 92, I am still trying to find a ECM. Does anyone know if the ECM controls the transmission? My concern is that if I purchase a ECM based on the VIN #, it will not work correctly with the automatic trans. Any thoughts would be greatly appreciated.

WVZR-1, I did get the harness and all the accessories with the motor and trans, it does have some damaged connectors but I think it's repairable. I did see the modules available online and through my local NAPA.

Unfortunately the donor car is no longer available and the harness was cut at the point where it enters inside the car, I'm starting to think that I've gotten myself into a expensive and possibly big mess.

Look at the 2 connectors on your blower housing and see if the harness from the donor has the same 2 connectors or if it's different OR were those aspects of the harness not included with your buy? You can't get the VIN of the donor? Do you have the FSM(Factory/Field Service Manal)?

For a '92, you might have a bit of a struggle to find an ECM at a decent price. They have been scarce for years. Only used I believe in the '92 and '93 as well as F bodies. It does control the lockup in the transmission.
