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.
