Specification
Description
The B&M Adjustable Vacuum Modulator is designed for GM TH350 and TH400 automatic transmissions, allowing drivers to fine-tune shift points and shift feel. By adjusting the screw inside the vacuum line connection, users can modify diaphragm preload, effectively raising or lowering part-throttle shift points and line pressures. This modulator comes pre-adjusted for normal shift points and includes a new O-ring to prevent leaks. Constructed from durable steel with a gold iridite finish, it ensures longevity and resistance to corrosion. The package includes detailed instructions for easy installation. Backed by a 1-year limited warranty, this modulator is a reliable choice for enhancing transmission performance.
