I finally got around to lubricating my throttle cable. It looked really good as far as the cable itself. I have no idea what the inside of the cable housing or cable itself looks like. I took the cable loose from the linkage on the engine and was able to slide a clear rubber hose over the cable and clamp it to the cable housing. I then held it, vertical and sprayed PB blaster cable lube into the hose. After the filling the hose three or 4 inches I would attach a Milwaukee battery powered compressor to the end of the hose and let it force the lubricant inside the cable housing until I could see it exit at the pedal. It works perfectly now and hopefully for many miles. I understand I may have to replace the cable in the future.



There are two cables that attached to the bracket the throttle cable is connected to. One is the throttle cable and the other appears to go to the transmission? Can someone tell me the function of that other cable? It appears that it is pushed when the throttle cable is pulled so I assume that cable may be under spring tension at the transmission?

One last question in this thread,,, what vehicle are the headlights in the monarchs taken from?

Thanks again for any help!

The other cable is the “kick down cable”. It controls, to a certain extent, when the transmission shifts, and tells the transmission to down shift when you need to get around another vehicle. Maladjustment, or malfunction of it will lead to premature transmission wear, so it’s just as important as the throttle cable.

Thank you, for the reply, do you have any idea where to get the information on the adjustment and setting of that cable? Thanks again.

The adjustment procedure is the same whether it’s a pickup truck or a coach. If it’s a TH400 transmission, it entails opening the throttle on the carburetor to wide open, while making sure there’s little to no slack in the kick down cable. It could’ve stretched over the years. When you mash hard on the accelerator, the kick down cable opens the valve body in the transmission, routing the fluid to downshift. If there’s a vacuum modulator on the transmission, make sure the vacuum tube is in good condition. The modulator controls the shift points based on engine vacuum. Some are even adjustable via a small screw in the vacuum inlet on the modulator.
