I have an 05 Verona which is shifting/jumping hard into R and in D but not as bad. It makes a clunk noise almost as if I'm dropping my transmission. Then at which point I put my foot on the pedal I have no acceleration. I once had this problem in 08 which I took to the dealer and they said it was an electrical problem since then I have lost the paper work and remember no other details. Anyone have any ideas or comments?
