back there in NY. I'm impressed with your extensive past posts on trannies!

I know I want to try something to revive this 722.118 tranny before giving it up to some rebuilder as a "core"... so I'll definitely file your suggested "test" on my short list of possibilities. I'm just not ready to rush into swapping parts between two different model trannies as well as leaving one of the old springs out altogether! That's a bit radical to be my first choice to try! Maybe later it will look better if nothing else develops!

You do call your recommendation a "test"... so does that mean there would be alternative actions afterwards depending upon how the "test" goes... or would I just leave it that way if there was enough improvement over what we have now ? Right now I have my Son pretty well trained to shift manually... and even how to use 2nd gear with a manual shift without it flaring until well above 25mph! So with this trick we are able to use all 4 gears and manually accellerate quite well! So we can use the car quite well as it is!

But I still think that M-B's reason for their K-1 kit for the 722.3/722.4 series was because of design problems... and it is entirely likely that the later trannies in the 722.1/722.2 series might very well have the same design flaw.

If the new spring parts are not too expensive, I'm game to give that a try, even if M-B's Classic Parts people never come through for me. Right now I'm asking my local M-B parts counter if they have a parts blow-up diagram for the valve body [aka "shift housing] so we can proceed to I.D. these springs in the 722.118.
