Does your M47 have a mechanical speedometer drive? M47II gearboxes do not have one.

Good point on that. I always forget the early 200 series cars used mechanical speedometers. Too accustomed to the 700 series which were electronic speedo reading off the diff for all years of their production.

Did M47I have a mechanical speedo cable drive? So if he could find an early year M47 it would work but M47II would not?

I don’t know if the M47I gearboxes (84-86) had a mechanical speedometer drive, the two M47II gearboxes I’ve had were in 87 and 88 240s, the speedometer gets a signal from the differential like 740s. It’s not as completely crummy a gearbox as claimed, but my opinion is based on the later version with an improved fifth gear.
