What would I need(ECM wise) to make this trans work with an 02 escalade motor harness and comp??? Could I have somebody like SPEARTECH just flash my comp to a 6 speed auto trans????

Thanks in Advance

The A6 wasnt supported in any ECM's until 06, so at this point you need an 06 plus ECM and 58X motor.

Only way to make it work is to swap out the crank trigger to the 58x, swap to the correct cam sensor etc... basically converting it to Gen IV motor. Then use the Gen IV ECM and harness.

It can be done but you have to take the crank out to change the crank trigger out.

I think it would be worth it though!
