Stock '50 Merc transmission with OD. Reverse will not engage if the OD control is "in". I have to disengage OD to back the car up.

In the shop manual transmission drawing, it appears there is a cam/lever in the transmission gear shift housing that, when in OD, and reverse gear is selected, forces the rail assembly back, shifting the sun gear into direct drive position.

I assume this lever is either broken or missing. My question is.... can I get at and replace this lever by removing the gearshift housing from the side of the transmission, or will it require removing the transmission and disassembling the whole unit?

Thanks in advance for any help.
