[W126 Coupe] Transmission Problems with upshifting

[Jonathan]

Interesting, well, I would take the valve body from the good trans and 
install it in the not so good transmission.  Just be aware of the 
plastic 'catch/slot' on the drivers side..if you don't engage that it 
Really won't work.  Also, there is a small spring loaded piece of 
plastic that rests in the valve body..when you drop the VB, don't turn 
it over, have a look @ where it sits..should you lose track I do have 
that info in my machine.

Also, pay attention to where the 3 short bolts go on the VB..I want to 
say they are on the passenger side but most of the transmissions I have 
been working on of late are out of the car.

All it takes is the tiniest piece of gunk to make it's way into the 
VB..similar pieces could all but never be found.
