I have a 1995 surburban and recently while driving at highway speeds overdrive quit working. I checked the fluid and no problems there. I don't have a TV cable on this truck (didn't come with one?) The tranny did shift hard from 1st to 2nd but now it shifts easy but have to get rpms up to 3000 before it wil shift into 2nd??
Give me details on what the problem might be and also how to fix it?
