Nope. The gearing on all MBZ transmissions (well ones we generally deal with) is the same. The only thing that changes is the gearing on the rear diff and the gearing in the speedo itself.

2.88 in a 123 was a 85 thing only. 126's do have 2.88 but I believe the have electronic speedos.

I think your flex discs are incorrectly installed. The engine rotates clockwise and the trans flange should be dragging, not pushing, the flex disc around by the thick part of the flex disc. Same with the diff.

Makes sense.... but I set it up in the original factory position and looking at other pics on the forum it is the same.

New disk


Original Setup.


Note same position.



Other pics from the forum and notice position of flex disk.

From R Leo





From Brandon314159





From Diesel Giant





I am actually taking down a tranny today in a friends 300D, I can take more pictures.

Searching for a 3.69 diff.

I have a 3.07 in my 300TD and with the mountain driveways we have to climb, I'd like to give the wagon some mountain goat gears. We rarely ever go 70mph. There is never a strong enough breeze at our back.

If anyone has one, thanks in advance.
