CARDER001

I think I have symptom number 4. Forgive me, but I'm not sure what the TPS is, or where it is located?? My 04 will sometimes shift hard into 2nd, only when I take off slow. All other gears are smooth and no slipage at all. I stumbled on to a youtube about the 1-2 Solenoid being bad?? I do not trust transmission shops, any advice much appreciated!
