72 W108 4.5 Tranny Slip

I own a 72 280 SE 4.5 that runs very well, however the transmission seems to be slipping a bit when shifting from second to third. I have very little cash and am trying to learn as much as possible about my car so that I can do most of the work needed. Any suggestions on what to check out before making the assumption that I need a rebuild?

Do a search for "transmission flare" or "flair" on the board.

Looks like I need to install a K1 kit?

Tranny oil and filter changed? Torque Convertor drained (and then filled with Tranny re-fill)?

If so, you can lengthen the pump pressure adjuster rod, a half turn at a time, so it activates pump pressure sooner.
(Not sure if this shortens transmission life; so far, so good for me)

Do you also have a noticable delay getting into reverse (can you count to 2)?

If so, there's a bolt on the passenger side with a no head (just square at the end) with a lock nut on it. Loosen the lock nut, turn it in a quarter turn and retighten the lock nut.

That bolt controls how the band is applied. It needs to be adjusted every now and then. When you reach the limit of the adjustment, then it's rebuild time.

There's a torque setting to use, but you can look that up after the quarter turn trick works (well, if the quarter turn trick works).
