My friend Jerry owned Jerry's transmissions for 35 years. He told me once" Do Not " flush your transmission. Change the fluid and filters regularly. On my Allison tranny
on my pickup there is an external spin on filter, it gets changed every oil change. When you check your fluid if it looks off color or smells burnt change it, even if it is not due by the mileage
suggestion.
I owned a transmission shop and would NEVER recommend a flush. Just drop the pan, inspect and replace fluid. If there is a lot of “mud” in the bottom of the pan, plan a rebuild soon. Probably sooner than you want as new fluid has detergents that will loosen up a lot of things that were glued together by old fluid.
It’s not the tranny shop that caused failure after a fluid change, it’s just a worn out transmission.
