I have a 2005 Jeep Cherokee (Liberty in US) KJ, 2.8 CRD Sport, with the VM Motori R428 2.8 litre Diesel engine (161 bhp and 296 ft-lbs (400Nm) of torque) mated to a six speed manual gearbox. A discussion came up, in one of the Jeep forums I frequent, that talked about the various transmissions used in the KJ and it said that the six speed manual gearbox was the NGS 370.
Clearly this cannot be the case with the CRD, because according to the Novak guide to the NGS 370, it can only handle a maximum input torque of 271 ft-lbs, and my Cherokee CRD is putting out 25 ft-lbs more than this!
So if it isn't the NGS 370, does anyone know what 6 speed manual gearbox it does use? An Aisin BG6??
