940 rebuild... should I?

This sounds to me like it’s got a TV (kick down) linkage problem. I’d go over my linkage to ensure it’s operating as it should. Could be binding or just simply not adjusted correctly. Why spend money when you could end up with it doing the same thing after rebuild due to another issue.

I've actually spent a ton of time on this (the kickdown linkage), unfortunately I think it's something in the valve body or up further. I put a new lokar cable linkage in and adjusted the hell out of it and I'm still at the this point unfortunately, it never got any better than this. I got 1 kick down out of it in the several months of fine tuning it.
