RE: Transmission Maintenance
Scott and Len, I appreciate the feedback.
Scott, I think I would agree with the Magliozzi brothers because I'm pretty sure their discussion concerns the type of flush I'd never consider (and no one else should, either): the "flush and fill" method. There are shops that do this now because it saves time, so they flush the thing, but force a whole bunch of crap into the filter, without ever cracking the pan or changing the filter. (I think this is akin to not changing a dirty diaper because sooner or later the kid will urinate enough to wash it out.) More and more shops (particularly of the "quickie-lube" variety) are doing this because it's so fast. What do we care how long it takes? We just want it done right. [:)]
All of that said, Len, if I could drain my converter I'd probably be more than happy with a drain and fill. My understanding is that if you just drop the pan on these things you only get about 2 quarts, so if you don't have the converter plug you're stuck. (And to continue the metaphor, changing 2 quarts is sort of like changing the diaper, but not cleaning up the kid.)
If you're at all interested, check the procedure they follow at Tanner Transmissions in Utah: http://www.tannertransmissions.com/Changing.htm
and this link is to a video of their process: http://www.tannertransmissions.com/Changingfilm.htm (this latter one will take a while to load, even with broadband).
In any event, the key here is proper maintenance, and I think we are in agreement that you have to do a fluid and filter change on the ATs, it's just the subtleties we're discussing.
Thanks, gents, and have a great week,
