error code 628 converter clutch error (E4OD)
what does that error mean. While driving home the shifting was VERY HARD a bad hard shift like there was no slippage in the tranny. 1st gear to 3 grand, BANG 2nd gear, from 2nd to 3rd not as bad and better from 3rd to 4th. If upshifting it was normal but down shifting was very hard. I pulled the codes and that was the only thing that came up as to what was happening.
