i agree completely. I can only add that the logic of changing the fluid in a transmission is akin to changing the oil in an engine. No one ever suggests that replacing the oil in an engine is a bad thing. I fail to see how doing the same to a transmission could cause damage. re the people

If you take a neglected tranny with ancient non-synthetic oil in it and flush it with fresh synthetic fluid, it's possible to remove enough varnish from the valve body that shifting problems arise. Also, in the 70's, synthetic oils didn't have enough seal swelling material in them, and

Do you want to replace the transmission? If Yes the do a flush if No the Drain replace the filter run it around 5000 miles and do it again. That will get most of the crud out of the TC. This comes form my buddy whose shop works VW's along with MB's BMW's. Factory trained Tech's for each car

I take exception to this statement. If flushing were such a bad thing, there would be literally tens of thousands of failed transmissions out there. I hear talk of fluid shock on occasion as well, and find this just as bogus. That is described as the condition where one drains and refills a

The speedy lube place we use has a system where they unhook the trans at the trans cooler and hook that to a tank which then pushes new fluid into the system as the transmission pumps the old out. Seems to work pretty well, we had it done a few times on the Dakota which went 222,000 on the

Just my personal opinion, but nobody hooks up a 'transmission flush' machine to any car I own. I have no trust in those machines and less trust in the people wielding them. If I want to change the fluid without a TC drain plug, I do something I saw in a factory Ford manual in the 1990s: Drain

The guy that has done mine (not any of my MBs, of course!) is a veteran indie mechanic that I trust. He's got the machine and been trained in its proper use. He says it does a great job getting all of the ATF out of the system and does it in a way that it won't damage anything. No way I

i think those flush and your tranny is toast thing comes from fords using type F in the 70s but changing it every 5k or so for a few times is not a bad idea if flush scares you. i used to change my tranny fluid ever 5k back in the day and the filter every 15 on the old hydramatics On Sat, Jul
