So will the 55556745 gearbox/transmission fit in place of a 55577516 gearbox/transmission?The gearboxes are interchangeable, but must be from the same engine (diesel - diesel) and with the same options (with or w/o start-stop)

Make sure that your problem not generated by the gear linkage cables.
Thats the problem with making blanket statements like "The gearboxes are interchangeable......" for a start there's different final drive ratios which wiould depend on engine power and also affect the speedometer drive. Then there's the question of 4 x 4 drive which the OP has conveniently "forgotten" to include any details about.
