This is a detail that ron.dittmer brought up some time ago: Those of you with a certain year(?) E350/E450 chassis RV make sure that - if it has it - you change the EXTERNAL transmission fluid filter per schedule.
My 2005 E450 has this filter and I wasn't aware of it's existence until Ron mentioned it. The first time any service shop mentioned changing it for me was after we had owned the RV after, maybe, 11-12 years!
I wonder if my external transmission filter wasn't perhaps nearly clogged and hence maybe the cause of the early failure of our E450's 5-speed TorgShift transmission at around only 60K miles?
This filter looks like it's IN SERIES with the transmission fluid flow to/from the cooler up front in the radiator - so a blockage of this filter means no, or little, cooling of the transmission's fluid. This was an expensive over-sight - if it was the cause in my case (over $5.5K for a remanufactured tranny - they aren't available new anymore).
