It then slowly gathered speed enough to make it home(about 70 miles). Vacuum is good to the modulator, and the VCV leaks off from 12" to 5" in about 20-30 seconds. When I checked the fluid right after it happened(before returning home), it was 1/2" high on the dipstick and had some small bubbles. After returning home and letting things cool for a day, the fluid was where it should be and the color looked ok(red not brown). Also discinnected the vacuum line to the tranny and it seemed to move a little better, although still flaring badly. Ordered 2 AT filter kits yesterday and will change fluid/filter, add Trans-X, run engine for an hour or so, drain and change filter, fill with AutoZone Dexron III/mercon(only kind available locally) and hope for the best.
Question: Should I also try to get the K-1 and K-2 kits and install them at this time? If so, what are the p/n's for them. Thanks for any advice as the closest M-B dealer is in Tucson(500 mile round trip). I really hope that there is a solution other than a rebuilt tranny.

PS, haven't pulled pan yet to see if any strange pieces down there as only place to work is open to the wind and dust(it's Mexico) and when I do open it up, I will need to make some kind of wind/dust barrier.

I believe we need to qualify "flare". When the transmission pulls properly in all gears, but disengages into a false neutral between gears, that's a "flare".

When the transmission won't pull the vehicle forward under normal revs.........and very high revs are used to move it........that's "slipping".........a completely different diagnosis.

It's important to state exactly what's happening with it and I don't believe it's a simple "flare".

If it won't easily move from a standing start in first and second gears, the problem is likely to be the B2 piston. Do some research on "B2 piston" and see if the symptoms are similar to what you've got.
