2000 pontiac GTP 3.8 with 170,000 + miles. was running fine until I let my son start using it. the car will only move for a few moments untl the car is warmed up and then no movement at all. if I let it idle in gear it will try to move, as soon as I step on the gas it will not move at all. what could this be?

Update on information for my question, when scanning this car I have two trouble codes. P0128 which I googled and it said it was a thermostat. The second code is P0742 which I also googled and it said this something to do with the torque converter clutch solenoid being stuck open. Is this something I can fix with out pulling the tranny?
