Has this tranny been regularly serviced? This is a unsual diagnoisis and questionable. For starter change fiuld and filter yourself and freshen things up a bit and check condition of inside of tranny pan for dirt and sludge and get a better picture of what is going on. I have a 89 burb with 172K on it 700R4 (predecessor to 4L60E) and it has been trouble free and still works well but it has had regualr servicing and fluid changes by me and has seen 5 or so of these servicing in its life. Nothing really wrong with a 700R4 or a 4L60E in relatively stock configurations and if they are properly serviced and cooled they will give a very long life.

Excause me but dirty oil does accelerate the wear in the bore duh... I have seen lots of these trannies go very long distances that have had regular fluid changes. People mistaking believe that a tranny does not need regualr servicing and nothing can be further from the truth especaily in a heavy RV.
