The B and M AUTOMOTIVE GM Throttle Valve Cable (part number 70242) is a precision-engineered aftermarket transmission control linkage specifically designed for the GM 700R4 automatic transmission. This adjustable-length throttle valve cable ensures proper modulation between engine throttle position and transmission shift timing, which is crucial for smooth shifting and optimized fuel efficiency across varying load conditions.
The adjustable length design allows technicians to customize the cable geometry for different engine bay layouts and carburettor or throttle body mounting configurations. This cable transmits throttle opening information to the transmission's throttle valve, regulating hydraulic pressure and governing shift points. Proper cable adjustment is essential, as too much slack can lead to late shifts and transmission flare, while excessive tension can cause harsh shift quality.
This throttle valve cable is ideal for restoration shops and street machine enthusiasts performing engine swaps in Chevrolet, GMC, and other GM platform vehicles from the 1980s through early 1990s. Worn or damaged original cables can lead to sloppy action, inconsistent shift quality, and loss of transmission responsiveness. The 700R4 remains a popular choice for small-block builds, making a reliable throttle valve cable essential for a functional drivetrain.
