Overview

FTI Performance Automatic Transmission Adjustable Vacuum Modulators

Fine-tune your Turbo 400 transmission's shift characteristics with the FTI Performance automatic adjustable vacuum modulators. Unlike a fixed stock modulator, these performance-calibrated units allow precise adjustment of part-throttle shift timing to match modified engines, aggressive camshafts, and street/strip vehicles. The result is improved drivability, better transmission response, and the ability to tailor shift characteristics for your specific combination in a simple bolt-in package.
