So here some information I found on some differences between the KM-145 and KM-132 trans. In my ignorance I thought they were identical with the only exception being the tail extension housing one for 4WD and one for 2WD. WRONG!! Attachment 5685 So here is some of scrap metal found when I pulled the pan. Attachment 5686Attachment 5687 Input shaft bearing, the scrap on the right in pic one is part of bearing that work its way through into main side of case and these are showing the reason for rebuild.
