Another tranny question

[bradley1997]

I just had a total flush done at my local Aamco, When I went to pick up my car they told me that there was an anti drain valve, or something like that, preventing them from totally draining the tranny, so they just put what new fluid they could in and then put a bunch of Lubegaurd in to clean up the fluid. Has anyone ever heard of this anti-drain valve? I thought that if you didn't completely drain the entire tranny that any amount of new fluid you put in would be contaminated by the old fluid. Should I call BS on these guys or are they right?

well, Aamco is the king of the bullshitters, and they completely fucked me over on my tranny rebuild, so i wouldn't believe it, but there could be a shred of truth in there. i drained the fluid in my automatic before i pulled it, and most of it came out, but when i took out the axles, even more came out. tell those retarded douchebags to remove BOTH drain plugs, and remove the axles.
