Hi,

The dsg gearbox in my wife's 2010 125TDI Jetta has apparently suffered the dreaded diff rivet failure. The gearbox in the car is an LTD code. I have a JPJ gearbox from a 2007 Jetta TDI.

Does anybody have any details on why these 'boxes would not be interchangeable? My plan would be to transfer the Mechatronics unit from the existing gearbox to the replacement box so that the car would think it has the same gearbox.

Does anyone have access to VW gearbox specifications so I could determine what if any differences there are in gear ratios in the two boxes?

Any help would be greatly appreciated.
