Throttle position sensor may need to be replaced or checked. Any codes? Check engine light on? As the 1-2 shift, the detent aka kick down cable may be out of adjustment.This cable runs from the throttle body into the transmission. It has a button on the cable near the throttle body on cable housing. Push it in and this will loosen the cable. With car off, mash the accelerator all the way down and this should reset it.

Transmission problems


It could be a sign of bad transmission solenoid. If so, your vehicle has trouble shifting into drive or reverse. Normally, when you start your car, you're able to shift into drive or reverse right away. With a bad transmission solenoid, the vehicle could have a delay of a few seconds, or even take several minutes to warm up and operate properly. During this delay, the vehicle will act similar to how it behaves in neutral. It won't stay in park, and when you press the gas pedal, the vehicle will make an engine revving noise but not move.
