I was driving and the van wanted to up-shift (like it was going up hill). Now I can't get it to go any faster than 30mph, it will shift fine. When you start it, it sounds fine, but when you step on the gas pedal, it sounds horrible. What's going on?
My van will not go faster than 30mph, why? on 1996 Dodge Ram Van 2500
