I have seen many posts re: oil changes using a MityVac (I also use the method for changing oil on my BMW), but was wondering if anyone does or recommends using the mityvac method (suck and fill) for ATF changes also...
My 2010 Escape with the 6F35 auto trans has no serviceable/replaceable filter = no filter changes with drain/fill service, so is there any harm in doing the mityvac method instead of a traditional drain/fill?
My goal is to do several suck/fill cycles to replace the full 9.5 qts of ATF new. (I have no idea how may quarts one can suck out with a MityVac; only about 4 qts can be replaced with a drain/fill on this transmission, which has already been done at 85k miles a few weeks ago: tech noted that the ATF was "pretty dark")
If any of you guys have attempted or done this: any tips/advice? any disadvantages?
(The one thing i am worried about is sucking ATF out hot/warm vs cold, due to the possible volume discrepancies of ATF at different temps.
I guess to be sure, I can suck it out when cold, that way both old AND new ATF is at same temp so I can just fill whatever volume I took out.)
