MDC: it's voila, lol
OK!!
I see this all the time.
It IS safe to get a Transmission Flush.
As long as they don't use the solvent. Get a flush, make them put, in writing, that they will not use the solvent. (it's only a can that they pour into the transmission filler before they start the flush)
That's the dangerous shit!
So, have them do the flush, sans cleaner.
Then, I would bring it home and change the filter, because where do you think all the loose junk goes? It clogs the filter over time.
You should be safe.
BTW: when they do a flush, they use 16qts of ATF. just a fyi.
there is a way to do it yourself. disconnect both cooler lines. find out which one is the suction line and place it in a clean container filled with ATF. plumb the return line to a container suited to hold as many quarts as you plan to flush through it.
a helper is probably a great idea...
when you're done flushing, let's say 12 qts through it, the fluid should be coming out clean and a nice red. shut the car off, reconnect lines to cooler and drain the pan. drop the pan down, replace filter. replace pan and top off.
Easy, right?
