problem engaging gears in automatic transmission

Yeah I doubt it's throttle POS sensor. Fluid level is most common when cranked up check the pan for leaks as well as any other seals if it's full and doing it may be modulator valve. You can get em at parts store to check if bad remove vacuum line and mod valve tap it against your hand and see if it has fluid in it if so it's bad.they're usually on rear of transmission above pan it'll stick out and have a vacuum line hooked up.

scan the computer for codes too.
