I have an 01 GTP 87k miles. I havent used it in 10 days, when i parked it everything was functioning normal. i started it tonight and the check engine light was on, retrieved the codes thru the aeroforce and cleared it. codes were p0122 and p01122, which have nothing to do with the transmisson. so when im driving easy its switching way later than normal on all shifts. and while crusing on the highway (looking at the aeroforce) in 4th gear i push the pedal a tiny bit to make it downshift, it skips 3rd and goes right to 2nd and the rpms shoot up and wont upshift until i release the pedal. i dont know where to start. please helppp

Are you sure that has nothing to do with the transmission? You don't even know what P0122 is ...or you'd have typed the name of it.

Let me google that for you

Here's a link to the FSM
GearChatter.com :: View topic - DTC P0122

And this particular sensor..FWIW... .has everything to do with shfting and transmission control.

I'm not aiming to be a dick, I'm aiming to teach you that you can do some diagnosing if you give it a try.
