Ok so I was getting a skipping sound and of course thought it was the belt skipping and apon inspection I noticed my tensioner pulleys were really loose on the bearings so i replaced them with aluminum ones and new bearings and a new belt and its still skipping . so ive removed the belt again and put it back together with out front wheel drive hooked up to isolate where the noise is coming from . and of course It still makes the noise in rear wheel drive only . So I took the tranny out again and looked it over and I just cant figure out what could be causing the skipping i dont see any teeth ruined on any of the gears .I noticed the idler shaft moves ever so slightly on the bearings and the top shaft also moves ever so slightly on the bearings . it doesnt look like its too much play but I dont know what else to look at . Im almost tempted to buy the HOTRACING.COM aluminum diff and idler gear and new tranny bearings but im not sure if its a good idea to have all that aluminum in the tranny like that . PLEASE HELP ME OUT WHAT DO YOU GUYS THINK
