This adapter allows the installation of the VW TDI engine to a Jeep transmission. It includes a 50 LB high inertia 3.8L flywheel and high torque mini starter.
The adapters are not transmission specific, they make the back of the TDI "look" like the back of the engine that the TDI is replacing. The adapters can be used with standard transmissions. 2WD or 4WD.
