Re:Re: tranny question



There are two switches in that transmission.  The one you asked about, in 
the shifter assembly, is tied into the seatbelt/ignition interlock 
unit.  Starting in '74, the seatbelts had to be fastened, with the 
transmission in neutral, when starting the car.  The interlock unit sits 
inside the cockpit, under the glovebox, and those cars also had a starter 
relay that earlier 115's didn't have.  So, your gearbox is likely a '74 or 
later version.  The switch can be left unconnected without causing any 
trouble, as can the "Butt sensors" in the lower seat cushions.  I can't 
tell you when that interlock system changed or was discontinued.

The other switch, in the bellhousing, closes when reverse gear is selected, 
and operates the backup lights.  The earlier (pre-'72) transmissions had 
that switch mounted in a bracket that was held in the bellhousing with two 
screws.  Your later transmission has that switch threaded directly into the 
bellhousing.
