what happened to it man i think i MIGHT be in the same boat as you not exactly positive.....
overdrive stoped working, im told it's a stripped 4th gear, and on TEP trans info, its a common problem, and they changed the design in later models, something like 03's and up.
I guess ill just have to get a TEP trans now
