The speedo may not be working because the speedo gear housing is wrong for the 3.73 gear. There were at least two "housings" used, one for the 3.08 and lower numerical gears, and one for the higher number 3.42, etc gears. You may have the 3.08 housing with the wrong plastic gear in it so it is not meshing properly.
I am in the process of converting from 3.42s to 3.08s and had to buy the 3.08 housing to replace the 3.42 collar i had previously installed. https://www.summitracing.com/parts/tci-880022 |

I figured out the issue with the speedometer. The headers I just replaced with the Gardner system were installed in a way that had them in direct contact with the speedometer cable. They basically melted the cable causing it to bind up and strip the gear at the transmission. I have a red, 37 tooth gear and also need a new speedometer cable. The link you provided above says it is for a TH-700R4 and I have the TH400. Will that item work on my transmission? Can I specify what color gear and the number of teeth? Are the cables unique to the car and transmission or will any cable work and just cut to fit? BJ

That's crazy about the kick down switch! When I had to replace the heater core on my 19,000 mile survivor 73 SD Formula, I found the same thing: the kick down harness was not connected to the switch and the wires were tucked and wrapped up in the upper dash. I was the first one to ever get into the under dash area and it appeared to have been that way since 1973.
