Yeah, at mega miles I figure there's got to be more wear throughout.

And with the Lucas did you do a quart fix - so I'd remove a quart first. Or does it want full strength (6+ quarts)?

I think the tranny has a long internal dip stick holder that goes all the way to the sump. So a topsider could vacuum out the fluid. Do you know if that's so? I'm looking hard at getting a Topsider for family's oil changes, and this could push me over.

I'd also like to know what you'd rebuild or replace when "rebuilding" yours.

In my case the lucas reduced the leak and helped with some of the shift issues.
You said it leaks and I think you likely know when it is a quart low. I waited till mine was a quart low and that is when I added the Lucas.

I can only help on the rebuilding issue if you are rebuilding a chevy astro van transmission. Note only by inspection did I find out what was wrong with my Chevy transmission.

There is some threads on it but around 2010 I stopped reading the transmission rebuild threads. So I don't know what is available.

Lucas isn't used full strength, add one to two bottles.

Topsider for oil changes...one of the best tools I've purchased buy one ASAP. I bought the Mityvac 8 quart version that works stand alone without an air compressor.

Good luck!!!
