Any way the encoder can be re-incorporated into the gearbox?

It also appears that the inner races of the bearings on the last stage touch the inner races of the bearings in the housing. Would this cause a problem due to the difference in speed of each shifting gear?

You have a good eye for detail. If this was real, I'd put a thin washer between the inner races like the bearings on the other side of the same shaft have.

The easiest place to put the encoder would be on the cluster shaft. This could cause a few problems - getting it to clear the CIM might be an issue, the speed might be too high for the encoder and you need to know for sure which way you were shifted.

That brings up another challenge - if 3 of the positions shifted and the 4th didn't you'd have a mismatch. If the shift position was detectable you could compensate the CIM speeds and get a "limp home" mode.

If the encoder didn't work on the clutster shaft, I'd probably try to change the shift cylinder setup so I had access to the end of the shaft (not sure what that would look like.)
