Useful Information

Description and Purpose:

Genuine Electronic Shift Control. Brand: Paccar®. Part number: Q21-6155-211R. Condition: New. Electronic 4-position shift lever for automatic transmission control, built for seamless gear switching on Peterbilt 579. Offers intuitive R-N-D configuration, electronic signal output, and perfect dashboard integration with Detroit DT12 systems.

Why Replacement is Important:

Gear selectors are a key point of driver-to-transmission interaction. A worn or malfunctioning unit compromises responsiveness and driver control. Replacing the selector helps restore safe, predictable transmission operation.

Impact on Vehicle Performance:

Inconsistent or delayed gear input may hinder fuel efficiency and vehicle performance, especially during load transitions. Smooth signal communication is essential for a functioning transmission system.

Manufacturer Information:

Paccar® is a recognized leader in manufacturing electronic truck components designed for long-haul reliability and compatibility with industry-standard transmissions like DT12.
