Trouble code P0715
 

Hi 2 days ago in the middle of going up the hill my 96 Accord's (4
cylinders) check engine light came on, then it stoped moving but car engine
still running. tow the car home and pull the code P0715 out of the car's
computer. Can anyone tell (hel...p ) me:
What P0715 means ?
How to fix the problem ?
Please don't tell me the tranny is gong! please! Thanks James
