I've got a '96 RR with 53K miles. When tranny shifts from 3rd to 4th, the rpm jumps up about 300rpm before locking into 4th gear. 'Sport' mode makes no difference. Am i looking at a total rebuild, or can this be an 'easy' fix?

when or if you run the snot out of the truck does it still do the same thing?

 

yes, only worse
