Classic Dash Dakota Digital Sending Unit - Manual

Man#650283
SEN-01-1
GM Transmission Sender Package
The kit includes the following parts:
Speed pulse generator (8000 ppm)
Coupler nut (sensor side 5/8-18)
Coupler nut (trans side 7/8-18)
Center cable/“key”
O-rings (trans and sensor side)
Installing the sensor to the transmission:
• Remove old speedometer cable
• Insert new cable/key into the transmission speedometer gear where the cable was just removed
• Place the larger flat o-ring into the transmission side coupler nut and seat it flat at the bottom
• Tighten the transmission side coupler nut onto the transmission
• Place the smaller o-ring onto the pulse generator over the brass tip flat with the threads
• To complete, the sensor coupler nut will thread onto the transmission coupler nut and the pulse generator.
The sensor coupler nut has left hand threads so just start those on to the transmission coupler and then start
the speed sensor on the other side, spin the nut and tighten both the pulse generator and the coupler nut.

NOTE: If transmission fluid is leaking from the sensor check o-rings. There is an internal seal in
the transmission speedometer output that should prevent leaks even with the cable removed, so
check this seal if leaks occur.
