I recently bought a 95 ford explorer sport with a 5speed. I have a problem it shifts great from 1st threw 5th but when you let of the gas in 3th 4th or 5th theres a grinding kinda whinning noise and i have to put it in nuetral till i get to a stop or keep on the gas. It only happens when i let off the gas when im going down a hill or just coasting. Its got a new clutch in it so any ideas on what my problem is?
