Rogiera Thermal Bypass Valve 3/8 NPT for 8L90

Description

Product Overview

The Rogiera Thermal Bypass Valve is a direct‑fit replacement for the OE# 125071000 used in 2015‑2018 GM 8L90 8‑speed transmissions. Crafted from high‑strength, heat‑resistant aluminum, the valve features a 3/8″ NPT inlet and outlet, polished exterior finish, and a built‑in neodymium magnet to capture metal particles. Designed to maximize fluid flow to the transmission cooler, it helps prevent overheating during demanding conditions.

Usage

This valve is ideal for Chevrolet Silverado 1500, Tahoe, Suburban, GMC Sierra 1500, Yukon, and Cadillac Escalade equipped with the 8L90 transmission. It excels in towing, heavy payloads, and stop‑and‑go traffic where transmission temperatures can spike. Install it in place of the factory valve to improve cooling efficiency and protect internal components.

FAQ

Is this valve compatible with all 8L90 transmissions?

Yes, it is a direct OE replacement for the 125071000 part used in 2015‑2018 GM models with the 8L90 8‑speed transmission.

Do I need special tools to install the valve?

Standard hand tools for NPT connections are sufficient. Ensure the threads are clean and apply thread sealant if desired.

How does the neodymium magnet improve transmission health?

The magnet attracts ferrous metal shavings generated by wear, preventing them from circulating through the fluid and causing wear on internal components.

What warranty does Rogiera provide?

The valve comes with a 1‑year manufacturer warranty covering defects in materials and workmanship.

Can this valve be used in vehicles other than GM?

It is specifically sized for GM 8L90 applications; using it on other transmissions may require custom adapters and is not recommended.
