Used Trailer Control Modules

We list 2 used Trailer Control Modules units from 1 sellers spanning 2 makes. The transmission shift assembly is the complete shifter mechanism, including the lever, housing, position sensor, shift lock solenoid, and wiring. It is the assembly that lets you select gears from inside the cabin. Automatic shift assemblies include the PRNDL position switch that tells the engine computer what gear you have selected. When this switch fails, the vehicle may not start (it cannot confirm Park position), the backup lights may not work, or the wrong gear displays on the dashboard. The shift lock solenoid prevents shifting out of Park without pressing the brake, and it can fail mechanically or electrically. Manual shift assemblies include the shift lever, boot, and the pivot mechanism. These are simpler but still vehicle-specific. Some manual shifters use a direct linkage while others use cables. Our sellers test automatic assemblies for proper switch function and note any issues. Top makes include Mercedes Benz, Bmw.
