High-Frequency GM-Style Pulse Generator
The missing piece of the increasingly popular early-GM
With late-model GM transmissions containing an internal speed
sensor outputting 128,000 Pulses Per Mile, the stock 40-tooth
(40 pulse per revolution) reluctor ring provided the
factory ECM with a high frequency input. The SEN-01-128 can now
recreate this missing high frequency rate when converting to an older
style transmission with a mechanical speedometer output.
With a standard female 7/8” thread-on fitting, the SEN-01-128
fits all GM transmissions with a mechanical speedometer cable outlet.
Removable weather-tight 10’ cable provides for simple installation and
cable routing. 128,000 Pulse Per Mile Sine Wave signal output is direct
replacement for the stock GM internal speed sensor, allowing the ECM
receive the signals it needs for proper operation.
NOTE: Fits GM transmission models with 7/8” Male Threading,
ie: TH350, TH400, 700r4, 2004r, etc.
