Hey guys I have a question. I pulled my tranny again because it quit pulling. After much investigation I ripped the splines in the case out that hold the planetaries in place. After talking with a few of my buddies they were telling me that loose chains in my transfer case can cause the output shaft to chatter causing this. Well Im haveing my case rebuilt also for GP since its never been done. Now that you have some backround thats probably unimportant heres my real question. Does anyone have the Part # for the seal that goes between the transfer case and the plate that joins the tranny and transfer case? I have looked all over and everyone say huh whats that we have never seen that before? This is getting very irritating and i really want my blazer back on the road. Thanks Guys and Gals. I would really appreciate your help. Oh by the way i have a 350/203 setup thats full time.
