The transmission is awesome. Only 10 K on mine, but it has been flawless.
The engine would be great too if you did the DPF delete and EGR block. When the everything is working right (DPF, etc. ) it is the best CTD ever. Mileage isn't the best, but would probably improve without DPF, EGR, and add a box that will advance the timing a bit. It's really quiet too.
