Problem is not the kick-down switch...
1983 300CD
WIth ignition on, the solenoid doesn't operate (click) when pushing the kick-down switch. 1. Kick-down switch tests OK with an ohm meter. 2. Two wires go to the kick-down switch; the Black/Yellow/Red wire has 12v. The Black wire has 0v. Touch them together - nada. 3. Further testing reveals that the black wire is not connected to ground 4. When I connect the Black/Yellow/Red wire to Ground the transmission solenoid operates OK Anyone know the location where the Black wire from the kickdown switch terminates? Cheers!

.... suppose I could just run another ground wire to the kick down switch, but I'd rather do it properly - and trace where the black wire from the kickdown switch goes.
Appreciate any/all advice. Cheers!

...it's the kickdown solenoid
My earlier diagnosis was flawed; The click I heard when shorting the kickdown switch 12v supply line to ground was not the KD solenoid - it was the ignition relay cycling. At the time of the test I was using a battery charger to supply power, because the battery is out of the car for battery tray R&R. I guess fuse #14 would have blown with the battery in circuit
I traced the black wire from the KD switch; it goes directly to the KD solenoid (rubber boot connector at rear of transmission). The KD solenoid on my car tests open circuit - measured between the solenoid connector and ground. I plan to replace the KD solenoid when I do a trans fluid change. Cheers!
