You can drive the car 5-6 miles before it acts up, wont pull. Cut the car off wait a few minutes then it drives until you stop and then it acts up again. Won't pull, no reverse, no forward pull. Wait it a bit then it does ok for a while.
Any suggestions

 

check your transmission fluid. if it's good, time to check the lockup solenoid, or could be time for a new trans.
