: Car shifting hard - how to reset all computers?

05-12-10, 09:27 AM
Hi all,

My car has been shifting odd recently, and I think it may be because of how agressive I drive rather frequently. I've pulled the negative cable off the battery twice for over 15 minutes each time, but still the car keeps all its radio settings and such.

What is the proper procedure to reset all electronics so I can see if the TCM is causing the shifting issue?

I guess if you really wanted to be sure you could do a reset by pulling the battery for 30 min then doing a crank relearn... Previous owner might have swapped out the stock and returned to stock to sell it and not done a crank relearn. just a wild stab in the wind but can't hurt.

Radio settings are stored in the Nav/Radio unit. Pulling the battery won't affect those.
