check the ratio drive adaptor its right off the trans the problem is the shaft wears out and it stops or you have a bouncing speedo or it reads really slow. I took mine out and just screwed the speedo sender straight into the trans and It starting working again problem is now it reads 87mph at 55. so its pretty far off and finding one is no easy task. Ive looked on-line and at the dealer (who have no clue)
