2012 GMC Sierra 2500 HD Transmission Electrical Parts

An automatic transmission is a hydraulic multi-speed device that does not require any input from the vehicle operator other than selecting vehicle direction. Hydraulic pressure is controlled by a series of electronic shift solenoids that are commanded by the transmission control module. Planetary gear sets and hydraulically controlled shift plates and brake bands apply power to the main shaft in the transmission and out to the vehicles drive wheels. The Transmission Pressure Control Solenoid controls the flow of fluid in the various hydraulic circuits.

Product Features:

• Product constructed to meet all design and operating characteristics as intended by the vehicle manufacturer.
• Precision-wound coated copper windings increase product durability and life cycle.
• 100% thermo-shock and vibration tested to ensure superior performance in extreme conditions.
• 100% end-of-line tested to ensure product reliability, every time.

This automatic transmission oil pressure switch is designed to match the appearance and function of the original switch, and is engineered to help monitor fluid pressure in the transmission case on specified vehicles.

Product Features:

• Direct replacement – this automatic transmission oil pressure switch is made to match the fit and performance of the original switch on specified vehicle makes, years and models
• Ideal solution – this switch is designed to be a reliable replacement for a switch that has failed from heat or fatigue to help restore proper timing and operation of the automatic transmission
• Durable construction – this button is made from quality components and materials for reliable performance and long service life
• Trustworthy quality – backed by a team of product experts in the United States and more than a century of automotive experience

The ABS or Anti-Lock Brake System ECU monitors the Wheel Speed Sensors rotational speed for anti-lock brake function, stability control and traction control. The ABS sensors report the speed of all four wheels to the ECU to determine if the wheels are locking up and to help provide safer stopping. Reasons for replacement include: ABS/brake lamp illumination, no or erratic ABS operation or problems with stability and or traction control systems.

Product Features:

• OE MATCHED: Manufactured to OE performance standards. Connectors, mounts and wire lengths are exact match to OE for worry free installation.
• INSTALLATION AND SUPPORT: Includes all necessary brackets and hardware. Application specific harness length
• THE DIFFERENCE: Glass reinforced plastic for better contamination resistance. Weather pack connectors prevent dirt and moisture contamination. Grease, mounting nut and instruction sheet included where applicable.
