Did you have the new TCM programed to your vin. after it was installed. It has to be programed or it still won't shift.

I would still call other dealerships to compare prices as each dealership is independently owned and operated.

Fixed now. Ended up costing a little over 800 dollars, but at least they changed the filter while in there too even though the solenoid wasn't under that pan.

I would have a reputable tranny shop at least diagnose which is the issue. The dealer is more expensive, and will want to fully replace the tranny rather than a cheaper rebuild.

So what cost of repair are we speaking of?
