My boy friend has a 1998 dodge ram 1500 4wd and he replaced the tranny not even 2 years ago and in april it went again and he thinks its because when they put the tranny in the last time they put a performance shift kit and ya sorry lol don't know really how to explain it but he said after they put that in that it was shifting harder and of timing he took it back in and they said it was fine Just wanting to know do you think that is what it could of been?
