I had tranny oil leaking out of speedo housing, good indication that tranny seal has gone bad. Drained trans case it was full of gear oil mixed with tranny oil. I have never removed a trans case. My ? is does the trans case mount unbolt by the 4 bolts that are bolted to tranny and the 2 on the cross member and come out as one piece after drive shaft is removed? And also does the front driveshaft need to unbolt or can it come apart and be removed with trans case?
