I ran into a problem with my tranny. It never had any problems whats so ever till I decided to give it a fluid and filter change...BIG mistake. Now it shifts from 1st to 2nd & 3rd at 10 mph. the only time it shifts different is when I get on it and then it still shifts a whole lot earlier than it should and it slips between 2 & 3rd. The tranny was nearly perfect before. Its a c-4 on a 302cid. Also I didn't Have time to do it myself so I got a shop to do it.
What could it be?
