Take Control of Your Shift Points

The B&M Adjustable Vacuum Modulator is a must-have for anyone running a TH350 or TH400 automatic transmission. Unlike factory units, this adjustable modulator allows you to fine-tune your shift timing based on your engine's vacuum levels. Whether you are looking for firmer, later shifts for performance driving or smoother, earlier shifts for cruising, this unit provides the flexibility you need.

Performance Benefits

  • Adjustable Tuning: Easily dial in your shift points to match your engine's power band.
  • Broad Compatibility: Specifically engineered for GM TH350 and TH400 transmissions.
  • Improved Shift Quality: Eliminates erratic shifting and improves overall transmission response.
  • High-Quality Construction: Built to meet or exceed OEM standards for long-lasting performance.

If you have modified your engine with a larger camshaft or intake, your factory vacuum modulator may no longer provide the correct signal to the transmission, leading to poor shift quality. The B&M Adjustable Modulator solves this by allowing you to compensate for lower vacuum levels, ensuring your transmission shifts exactly when it should. This is a simple, cost-effective way to improve the drivability and performance of your classic GM vehicle. Installation is straightforward, making it an ideal weekend project for any car enthusiast. Find all your transmission tuning components at GGCRACING and optimize your vehicle's performance today.
