What is the purpose of the 'foot / toggle' switch ?

is this system fully automatatic operation with no input for the operator ?

does the original speedo drive gear get transfered to this new unit ?



Bill, the "foot switch" enables the driver to manually turn the system on or off. Like, if I was cruising around town when rpm's aren't an issue or when I go to pass someone on the highway.

A new speedometer pinion and assembly come with the overdrive unit. When you order one, you are asked what rear gear ratio your car has and what the diameter of the tires are. The appropriate speedo pinion gear and speedo assembly are included in the kit.

The system can be operated in an auto-mode. In this mode, the car will shift by itself at around 45-47mph. 1st thru 3rd is just like original. Most of my driving will be like this.
