Product Details

The B&M 20234 Adjustable Modulator is designed specifically for GM TH350 and TH400 automatic transmissions, giving you precise control over shift points and transmission behavior. This fully adjustable modulator allows you to fine-tune your transmission's performance to match your driving style and vehicle setup.

Key Features:

  • Fully adjustable design lets you tailor shift points for optimal performance
  • Compatible with GM TH350 and TH400 automatic transmissions
  • Includes new O-ring seal to help prevent vacuum leaks
  • Built to B&M's quality standards for reliable operation
  • Easy adjustment allows you to increase or decrease line pressure

By adjusting the modulator, you can firm up shifts for performance applications or soften them for smoother daily driving. The included O-ring ensures a proper seal against the transmission case, helping to prevent the vacuum leaks that are common with worn factory modulators. This is an essential upgrade for anyone looking to optimize their TH350 or TH400 transmission performance.

First time user, went smooth without any issues. And lowest price

Awesome place to buy goods. I wasn't able to find the item I bought cheaper anywhere else. I will definitely buy from autoplicity again.

Great product, fast shipping!!

quick and correct

Unbeleively fast shipping. I ordered on a Tuesday night, and it was delivered to my door by Thursday. Plus, the item was the cheapest with shipping on the web! I will most certainly be doing business with them again!

Great selection and easy checkout! The only thing is I didnt get an email confirmation as soon as I order which made me wonder is the transaction went through. I did get an email once the items were shipped though.
