Allright, let me start off by saying I have a 94' Cougar 4.6L v8 all stock and around 135-140k miles on it. The transmission fluid was changed around 1000 miles ago (in mid August) with Mercon V.
Heres the gist of my problem. About two weeks ago driving home when I hit about 40mph (in that area) my car would not shift and any result of trying to accelerate would result in the engine revving heavily. It wouldn't shift until I dropped back around 30mph or below. I shook it off that it must have just had a hard time shifting up on the steep hills around here.
Anyway, so the other night the same thing has happened again. I did a search around the boards here but couldn't find anything similar (at least in my knowledge).
Does anyone here have an idea of what this could be and if so, the probable cost to the solution? I'm not in Houston, or I'd go take it by the "family mechanic." I don't know any of the shops around here in Oxford, MS to trust whethered theyd give me a straight response or reem me for everything I'm worth.
