Well the new Renault / Nissian 2.0 Diesel engine for the Lag II is a joint venture but the new engine is coupled with the new PK4 gearbox, also made at Renault’s Cléon powertrains plant in Normandy. This six-speed three-shaft manual unit, derived from the PK6 currently used with high-torque engines, introduces a number of special developments.

With its reinforced bearings and gear trains, the PK4 gearbox handles torques up to 360 Nm. A die cast aluminium casing gives low weight (54.5 kg dry) plus rugged resistance. In addition, the PK4 also features a more compact spherical differential.

The PK4 implements ultramodern engineering upgrades to minimize the noise characteristic of manual gearboxes. Acoustic resonance phenomena are reduced by using contoured housings, close to the shafts and gear trains. Reverse gear is synchromeshed, which means it can be engaged before the vehicle comes to a complete standstill, a further convenience enhancement for this new transmission.

That's the blurb - time will tell !
