Transmission Model Designation ??
 

Being a newbie owner I have a question or two on proper tranny I.D.

A 1987 N.A. 300SDL is the subject and am attempting to correctly identify the transmission service manual.

car model is 126.125

engine model is 603.961 - 3.0 lt. diesel

transmission is 722.321

All according to the technical identification in the front of the car service manual and PDF datacard downloaded from EPC today, I quote the above info.

What is the proper manual number for this tranny? I have the manual with the cover sheet attached but inside it does not align with the 126.125 car.
Can someone direct me to the correct manual please?
Thanks,

It looks like that manual is for a 461/463 G Wagen, not a car. so even though they both use the 722.3 trans, I don' tknow if you can use that manual, more than likely the G Wagen has some additional stuff going on due to the transfer case. You've more or less answered your own question, I don't knw where you are getting the manuals from, so don't know what else to tell you, you need a 722.3 manual for passenger cars.
