Help Please
 

Two questions:
1. How do you go about changing the trans valve body?
2. How do you do the Key Switch Trick?

Can't help you with the valve body, but I do know that the key trick only works on trucks from 2000 and later, so not yours... :s:

Key trick doesn't work on yours you need a OBD2 scanner.
