System Description

DESCRIPTION
Pulse Generator A
Measures the input rpm to the transaxle after the torque converter.

The outer circumference of the of the kickdown drum has 4 holes drilled in it. As the drum rotates, the holes are moved past the pulse generator, causing a fluctuation in the magnetic field within the pulse generator. These fluctuations are transmitted through the pick up coil as an electrical signal.

Pulse Generator B
Measures the output rpm of the transaxle before entering the differential.

The transfer driven gear has a number of gear teeth. As the gear rotates, the teeth are moved past the pulse generator, causing a fluctuation in the magnetic field within the pulse generator. These fluctuations are transmitted through the pick up coil as an electrical signal.
