Product Overview

The 29509886 is a genuine Allison vehicle interface module designed for specified Allison automatic-transmission applications. This VIM serves as an electrical interface within the transmission-control installation and uses a 12V, six-relay configuration.

Product Features

The 29509886 transmission control module is manufactured to Allison factory specifications for managing automatic-transmission operation.

  • Processes inputs from multiple sensors to determine the operating conditions used by the transmission-control system when making shift decisions.
  • Coordinates transmission-control activity with the engine ECU to establish the required response for current vehicle operating conditions.
  • Determines when a gear change should occur based on the operating information received by the transmission-control system.
  • Determines how long the transmission remains in a selected gear before the next commanded gear change.
  • Regulates shift pressure as part of the transmission-control process used during automatic gear changes.
  • Manages shift timing to coordinate when the transmission carries out a commanded change between gears.

Installation Notes

The 29509886 should be matched to the vehicle’s original VIM identification before installation. Confirm the 12V electrical requirement, six-relay configuration, and exact transmission application.

Verify the complete module identification and vehicle configuration. Related part numbers alone do not establish compatibility.
