Switchs on Rib Cage Transmission

Postby papa » Thu Nov 01, 2012 4:42 pm

I have a ribcage transmission in my 64 A-H Sprite. I think it's a later model transmission. At the back of the transmission, below the shifter, there are two screw-in switches. I know that one is for back up lights, but no idea as to what the other one is for. It has two black wires coming out of it. I have checked the manual, but I can't find any information. I appreciate your help. Thank you. God Bless.

I have one of those ribcage trannys also with the 2 switches. I metered it one time and I think it closes anytime you are in gear. Probably used in later cars for some type of warning feature. I'm sure someone else knows what the exact purpose is.

Update, I found it in the Haynes and Bentley manuals. Listed as a Seat belt warning gearbox switch #201 used on 71-72 Midgets. See diagram 10 in Bentley, Fig 10.28 pg 205 in Haynes manual.

Hallo Papa.
I remember that I read in the Haynes restoration guide that for one market there had to be a warning light for gear in or so. Just like on bikes.
I'll try to find it.

Hallo folks,
I got it!
Original Sprite& Midget Terry Horler page 107 Transmission:
With the introduction in October 1969 of the facelifted HAN10/GAN5 versions ....
A new gear lever knob for the "round-arch" Midget replaced the traditional BMC item. Soon after, from engine number 12V 587 ZL 7591, the remote control housing and remote control shaft on North American cars were changed to accommodate a gear lever position sensing switch for the seat belt warning light buzzer.

Nearly what I remembered :wink:

Some rain since high noon here
