Driving back home from school (anxious to start my dual case conversion) my truck began to sing an odd high pitched whine from the transmission. So i pulled the plug and found shavings in the oil <img src="/forums/images/graemlins/frown.gif" alt="" />. The thing that gets me is that when i took off the shifter, there was a little mound of dirt right on/around the shift forks! Still have no idea how it got there, but regardless i need to do something about the transmission.

Has anyone rebuilt their transmission before, and if so how difficult a task would this be? I'm considering getting Marlin's kit so i can just upgrade it with the stronger bearings--turn it into a G54--. I've previously done a 4.7 gearkit to my t-case so the project doesn't seem too overwhelming, but i havn't found a guide on how to rebuild the tranny (or at least not yet)
Does anyone know of one?
Anyways hit me up with some ideas/advice
