My 95 gt has a shifting problem. At full throttle from a stop or 25 mile roll it shifts down then as the rpms raise and it should shift. it doesnt. i have to let off and it acts like its goin into nuetral. then it will finally shift into 3rd. When jus driving arount town the rpms climb high in second. sometimes it will shift sooner. then sometimes it will go real high and i have to tap on it and play with the gas. Its only from 2-3. I thought maybe it was my chip. since it did mess with the tranny. unhooked it. and the same problem. Checked my fluid. Fluid is clean and smells fine. Any ideas?
