Oh ok then. As for me on my computer part i've got HPtuners and i deleted anything and everything that had to do with the ShittyE. Only problem i've got now is my hatch wont open bc the car doesn't know what gear its in bc the hatch will only open in neutral or park i believe.. All you need to do is ask your tuner to do this for you and im sure they know what to take out and stuff like that.

Nothing your check engine light will stay on all the time from trans codes for a trans thats not there. I have never understood this swap though a th350 is not substaintially stronger than a 4l60e in fact you would be amazed just how similar they are.

If its a 94 you wont even get a check engine light. I have had my TH400 in for over 1500 miles now and I did not change one thing in the PCM. Runs fine, no SES light. I do plan on getting all my little things done like deleting the auto trans stuff and changing for my 4.10s instead of 3.73s and a 28 inch tire instead of a 26 inch tire.
Bottom line is it will be fine to drive it without changing the PCM.
And we both know why your changing to an A3......good call in my opinion.
