Hi all,

My car has been shifting hard recently - and I want to reset all computers by pulling the battery. I've pulled the negative cable twice for 15 minutes each time, but the radio setting remain which makes me think the TCM wasnt reset.

Any suggestions?

Don't worry about the radio settings. they stay for a long damn time. 15 min should do the the ECM/TCM
