Sonnax 77872-01 Shortened TV Link for GM 700R4/4L60 Transmissions

The Sonnax 77872-01 is a shortened throttle valve (TV) link designed for GM 700R4 and 4L60 automatic transmissions. This precision-engineered component plays a critical role in transmission performance by connecting the TV cable to the throttle valve plunger within the valve body.

Key Features:

• Shortened design ensures proper TV cable readjustment during installation
• Synchronizes engine throttle movement with TV plunger movement for optimal line pressure
• Helps prevent soft shifts and premature clutch or band failure
• Ideal for carry-out transmission units and rebuilds
• Sold in a convenient pack of 5 links

The TV cable system is critical for proper transmission line rise and shift timing. This shortened TV link is shorter than the OE so that the installer must readjust the TV cable, ensuring correct pressure settings and preventing common transmission problems such as burned 3-4 clutches or bands caused by improper cable adjustment. Sonnax transmission components are trusted by professional transmission builders and technicians worldwide for their precision manufacturing and reliability.
