Hello people,

Am new to the forums Could use some mercedes expertise!

I was wondering if anyone could help me please. I am currently in the process of installing an Om602 with a 722.6 (I believe taken from an e300td) into my 1981 ford f250.

Engine and trans are in and now I'm just trying to make everything work! I'm at the stage of ytring to install the gear shifter, the only problem I'm having is that i can't get the gear selector arm on the trans to shift from park!

Am pretty sure the trans was working fine before. I had someone service it before it went in. Also I have a spare trans and the spare was moving fine through the gears and now is also stuck in park! Some research has told me that the Pawl is whats's doing it and that some torque applied to the trans output shaft will at the same time pushing on the gear selector arm should free it but this doesn't seem to work (on either transmission). Some more research has suggested that once the propshaft is installed - I don't have it yet, it's still being made), then by pushing the van forwards and backwards a little should provide enough torque to free the pawl, but honestly i don't see how this could be the case every time i put the truck in park.

I then started thinking that there must be some sort of solenoid or electrical signal required to free the trans but chatgpt is adamant that the722.6 should be purely mechanical (when not connected to the shifter assembly, and the the shifter assembly itself is what has the solenoid in?).

I have an OleGear aftermarket controller to manage the trans.

Anyway i sure could use some help with this if any of you good people would be able to illuminate me some!

Also on a last note, I have heard that the 722.6 is quite particular about how the shifter works with it and that it can throw itself into 'limp mode' if alignment is slightly off. if anyone has some advice on how to get it right first time that would also be greatly appreciated!

Thank you in advance,

Andoni
