(06-23-2019, 01:35 PM)flyer I have seen that people are using stand alone electronics to shift a 722.6 and I was assuming that dead electronics would probably disable the transmission.

Has anyone done something like a full manual push button control that's all switches and relays instead of a microcontroller?  I would love to carry something like that as a spare.

I forgot to ask earlier, is there any difficulty putting a RWD 722.6 in a G Wagen with it's transfer case?

Hopefully I can get a 90's G Wagen that has more similarly with the G500 model that I can find some used parts for.  I would like to do some interior upgrades and I hope wrecked G500s would be good for drivetrain parts.

I understand that a big bore injection pump would be needed and maybe a turbo swap.  Does anyone have a comparison of the torque characteristics of stock and mild upgrade turbos on an OM606?

Is there any torque level where the bottom end becomes the weak link in the engine?

I would like to use as many stock parts as possible and just keep the power low enough to be reliable.  That will guide my choices for the parts I do need to change out.

The 722.6 is complicated enough that there's no way you'll shift it using relays. The solenoids must be powered in a sequence to complete a shift.
