95 F-150 5.0 115,000 Miles. Bought the truck with 95,000 on it. Not knowing if the fluid has ever been changed, and I like to stay on top of maintenance, I called a couple of transmission shops to check about having the transmission fluid changed. Not flushed, just changed. Both refused, saying they have had alot of trouble after changing the fluid on high mileage ford transmissions, the E40D in paticular. They explained if the fluid has been changed regularly, they would do it, but if it has not been changed in along time, they would not.
I would have thought new fluid would be good for a transmission. What gives?
