The difference between the G version of the 722.6 and the others is simply a 16 tooth attachment to the parking gear. And, of course, the corresponding sensor that has to be threaded into the housing. Unfortunately, the entire transmission needs to be disassembled to get to the spot where the...

What I do know is that people building OM606A's for high power have been using both the passage at the left rear of the head and a pump to move heat out of the back of the engine. They claim it helps prevent meltdown of #5 and #6. You might want to dig into the subject at...

The part in the G is A0005062564. Of course, being a G part, MB wants $$$ for it. I suspect that any "MB heater monovalve" will do the trick. It is plumbed so that coolant will flow around the heater and heater valve when the power is off. The monovalve is smaller than the hose diameter, so...

MB sells a normally open coolant valve for doing just that. It is used on mid-90's G wagens. I can get you the part number if you want.

You are doing just fine on fuel economy. The G is quite heavy and has famously lousy aerodynamics. 2600rpm in 5th is roughly 65mph. My lifetime average is 19.5mpg (over 200K miles).

I have the factory OM606A setup in a Mercedes G. It runs ~3-4 PSI of boost at a steady 60mph. The wastegate is controlled by the ECU. Boost is actively manages so that there is just enough air with minimum backpressure. The control line (vacuum) is constantly changing to match the need...

What transmission did the OM613 come with originally? I would assume that the Mercedes 722.6 transmission would be a direct fit. Those are very strong and can run with a simple stand-alone controller.
