truck the trans temp light comes on the the O/D
light I park it and let it set turn it on and drive and it

The lights are both for the transmission, not the engine. Check transmission fluid. If it's low or dirty, this can turn on those lights. If fluid is OK, it's probably a solenoid or a pressure imbalance in the trans and you'll have to go to a transmission shop.
