primary input shaft size...

Post by Sidewaze Samm » Mon Aug 15, 2022 6:51 pm

My son has the opportunity to upgrade his zed (2005 2.5 M54) with a 6-speed gearbox, as he may have access to a similar aged box and complete drivetrain from a 3.0 M54

I believe swapping everything should mean it will work, and the larger clutch and the flywheel from the 3.0 won't be needed as the engine is staying the same 2.5

Question - does anyone know if the primary input shaft on both gearboxes is the same? Will the 3.0 'box mate into the 2.5 ?

happy days if it does - bummer if not...

Is this for certain? I hope so, but have picked up that the 5-speed is a ZF box and the 6-speed is Getrag :idunno:

Anyone else got any input on this at all?
