Ok so as I hit the gas I speed off, but as I start to slow down the trans down shifts hard and the RPM's spike to 4000 or so. Then as I drive off after that say from a light it revs real high before it will shift, and when it does it shifts hard/jerks. It does it in all gears then. If I do some revs in Neutral as im driving I can get it to shift correct. Anyone have some kinda idea? It would help me out. Thanx
