Q216155211X | Genuine Paccar® Shifter Stalk Control Assembly RH

1. Gear Selection

• Enables the driver to shift between Park (P), Reverse (R), Neutral (N), Drive (D), and low gears
• In automatic transmissions, sends electronic signals to the Transmission Control Module (TCM) to execute smooth gear changes

2. Improve Safety and Ergonomics

• Mounting on the steering column keeps hands near the wheel, reducing driver distraction
• Simplifies shifting without needing a floor-mounted lever

3. Additional Vehicle Controls

• Many modern shifter stalks include buttons or switches for:
  • Manual tiptronic mode
  • Overdrive on/off
  • Cruise control activation
  • Sometimes even wipers or turn signals in integrated designs

4. Support Transmission Efficiency

• Provides precise control of gear selection, improving fuel efficiency and engine performance
• Reduces wear on transmission components by preventing improper shifts

1. Gear Selection Issues

• Unable to shift into certain gears (e.g., Drive, Reverse, or Park)
• Gear indicator on dashboard doesn’t match actual gear
• Transmission stuck in one gear

2. Erratic Transmission Behavior

• Transmission shifts unexpectedly or not smoothly
• Delayed engagement when shifting from Park to Drive
• Engine revs spike without corresponding movement

3. Dashboard Warning Lights

• Check Transmission, PRNDL, or Service Transmission lights illuminate
• Sometimes combined with ABS or traction control warnings if integrated

4. Loss of Auxiliary Functions

• Buttons or switches on the stalk (like overdrive, tiptronic mode, or cruise control) stop working
• Turn signals or wipers may also malfunction in integrated designs

5. Physical Stalk Problems

• Loose, stiff, or wobbly stalk
• Stalk feels “sticky” or doesn’t return to its neutral position
• Clicking or mechanical resistance when shifting

6. Intermittent or Inconsistent Behavior

• Shifts may work sometimes and fail other times
• Common in electronic shifter stalks with faulty sensors
