Hey guys it`s been about a year since my last post ,just have a question. I bought a 1996 GT 4.6 automatic. Car has 97,000 miles on it. When I drive it it shifts fine untill it gets to operating temp and then when it goes into overdrive it just revs up,like there is nothing there, if you take it out of overdrive it is fine WTF? No flashing light, no codes, fluid is clean ,not burnt in any way. Anyone have an idea on this? Thanks in advance guys !
