Truck will shift from first to second but when it goes to shift into third the engine races and it falls back to second. Will not shift to third or overdrive.

Have a trans guy scan for codes. But you didn't put mileage down and age I would n't be surprised if it's time for a rebuild.

Was coming over bridge and it down shifted to slow to a 40mph zone. It was fine until then. I haven't had truck long. The motor has only around 40,000 on it. Don't really know about tranny. It has been cared for. Fluid looked good and it hooks up great in first and second. Just can't afford a rebuild so really hoping it's a sensor.
