that was my only concern. I bought the truck with 97k on it, now its just over 100k and the factory now recommends a trans flush. the fluid looks contaminant free and relatively clean on the dip stick, but i have no way of knowing how its been maintained in the past... makes me uneasy a bit.
will be flushing tomorrow morning, then monday pulling 4k pounds for 2k miles
the million dollar question is; what's worse for the truck?
hauling a long distance on old fluid that can't handle the thermal breakdown of the heavy load and burning something up,
or freeing up contaminants in the trans that could possibly clog/and or cause issues/failures in the trans while on the trip???
can i borrow someone's crystal ball please???
