Drop-in Valves for 4R70W

Easy no-reaming solution for gear shifting issues:
Our valves with a diameter of +0.015 mm help to quickly and effectively repair 4R70W valve bodies when valve bore wear is not critical. No need for reaming; just polish the valve body bore before installing the new valve.

Durable coating:
The valves are coated with cold, hard anodizing, resistant to wear and ensuring a longer working life.

High manufacturing quality:
Our valves are manufactured on high-precision CNC machines, adhering to strict tolerances. However, if there are any issues, we offer a solution: returns or replacements if the quality doesn't meet your expectations.

How it works:
Our valves are larger than the originals by 0.01-0.02 mm, often sufficient to restore proper clearances in the valve body. However, please note, if the vacuum tester shows 10 inch Hg but you require 20, it's better to immediately install the oversized valve.
