hey i have a 88 1 ton when i bought it it had no over drive just recently i had fixed a ground wire that wasnt getting a good conection and replaced a few plug wires and i got my overdrive back but it only lasted for a week or so. well i guess my question is if the plug wires or the ground have anything to do with it or just a fluke either way any help you could give me would be greatly apprieciated
thanks in advance
