I have a 1990 camaro with a 305 v8, an automatic tranny (700r4) and it is not shifting correctly... we have rebuilt a blown tranny completely and ever since i have been driving it, it hasnt shifted correctly... Ill be driving down the road and it has to over rev to shift to second or third. when im in second or third and i gun it, it doesnt shift up like it is supposed to...anyone know the issue?
