ACDelco GM Genuine Parts Automatic Transmission Control Valve Body Assembly

The ACDelco GM Genuine Parts Automatic Transmission Control Valve Body Assembly (also called a transmission valve body or transmission control valve assembly) is a key hydraulic component of a GM automatic transmission. The valve body directs pressurized transmission fluid to the clutches and bands. This controls shift timing, shift quality, and gear selection.

Key Features:

• Genuine GM Parts engineered to original equipment specifications for dependable fit and function
• Routes transmission fluid through precision-machined passages and valves for smooth, accurate shifts
• Supplied as a complete assembly to simplify replacement
• Helps restore proper shift performance when the original valve body is worn, sticking, or causing shift concerns
• Backed by ACDelco, GM's official parts brand, and its OE-level quality standards

Replacing a worn or malfunctioning valve body can help resolve harsh or delayed shifts, slipping, and erratic gear changes. For best results, install it with fresh transmission fluid and a new filter, following the vehicle manufacturer's service procedures.
