I just swapped my OEM TR6060 shifter for an MGW Gen2. Reverse is difficult to engage now. It grinds and strangely, the speedometer increases even though the car is standing still with the clutch engaged. With the OEM, I would put it in 3rd and then reverse and all was good most of the time. Now, I do the same and it grinds and when it does engage, the car shakes. Does anyone have some insight to this?
