5HP 24 AUTOMATIC TRANSMISSION SYSTEM
TCM Inputs – Transmission (continued)
Transmission Rotary Switch
The digital rotary switch is mounted on the right hand
side of the transmission and is operated by transmis-
sion gear selector shaft. Selection of a particular gear
generates a 4-bit binary coded signal which is transmit-
ted directly to the TCM over a four wire parallel
interface. The rotary switch bolts directly to the trans-
mission case and does not require a service tool for
installation.
In addition to the gear selector positions, the rotary
switch incorporates a separate Park/Neutral open/close
switch used for engine start inhibit.
NOTE: If the selector cable is incorrectly
adjusted, the range selector may transmit an
invalid code, which would cause a DTC to be
flagged.
