My 98 Dodge Grand Caravan (3.0L V6) has just over 100K miles on it. I
figure it's time to change the tranny fluid, since I never have. It
has no leaks and I've had no trouble with it at all. This is just
preventative.

It would have been *preventive* if you'd done it 70,000 miles ago and
40,000 miles ago.

I'm no mechanic, so I'm going to take it somewhere to have it done.

OK...

Places I've called fall into two camps:
1. Flush the whole thing with new fluid. Leave the old filter in.

Wrongo. You need a new filter. There is no debating this point. Those who
say to leave the old filter in simply want to charge you full-service
pricing for a half-assed job. The pan MUST come off. The filter MUST be
replaced. Period.

This supposedly removes all the old fluid, and basically cleans the
filter as well.

The filter cannot be cleaned.

Not dropping the pan means no chance to introduce new leaks.

Replacing the pan correctly, with the correct gasket, means no chance to
introduce new leaks.

2. Drop the pan, replace the filter and pan gasket, and drain the old
fluid.

Right. That's how it's done.

Quote:

This leaves about a gallon of old fluid in the torque
converter.

Unless it's removed by any of several acceptable ways to do so, none of
which is difficult.

Put in new fluid.

Yes, and make DAMN sure it's ATF+3 Type 7176, and NOT Dexron (alone or
with any kind of "special" additive.
