I just got my car back from body shop and I floor it from a stop and it upshifts, does not spin wheels and no power off the line. What could be the problem? They replaced all radiators, oil cooler, heat exch, ac condenser, rad fan. Tranny fluid level ok. All vacuum hoses look ok. This has kleemann ecu/tcu so it normally lights up tires even with esp on.????????
