Rogiera Thermal Bypass Valve Aluminum 3/8 NPT

Description

Product Overview

The Rogiera Transmission Fluid Thermal Bypass Valve is engineered for the demanding environments of 8L90 8‑speed transmissions found in 2015‑2018 Chevrolet Silverado, GMC Sierra, Tahoe, Suburban, Yukon and Cadillac Escalade models. Constructed from high‑strength, heat‑resistant aluminum, the valve replaces the factory plastic component, offering greater durability and resistance to thermal degradation. It features a National Pipe Tapered (NPT) 3/8″ inlet and outlet, two‑port design, and a built‑in neodymium magnet that captures metallic particles, protecting internal bearings and gears. An O‑ring sealed service plug guarantees a leak‑proof connection, while the polished exterior finish provides corrosion resistance.

Usage

This valve is ideal for drivers who regularly tow heavy loads, navigate steep grades, or encounter frequent stop‑and‑go traffic. By maximizing fluid flow to the transmission cooler, it reduces overheating risk and maintains optimal operating temperatures, extending the life of the transmission. Installation is straightforward for anyone familiar with basic automotive repairs; the valve bolts directly into the existing NPT ports, requiring only a torque wrench and standard hand tools.

Why Choose Us

Rogiera’s commitment to precision engineering ensures each valve undergoes rigorous testing, including 500+ thermal cycles, to verify reliability under extreme conditions. The larger magnet surface area captures up to 30% more metal debris than competing designs, and the aluminum construction outperforms plastic alternatives in both strength and heat dissipation. Backed by a one‑year manufacturer warranty, this valve delivers peace of mind and measurable performance gains for demanding applications.

FAQ

Is this valve compatible with all 8L90 transmissions?

Yes, the valve is a direct OEM replacement (OE# 125071000) and fits 2015‑2018 GM trucks and SUVs equipped with the 8L90 8‑speed transmission.

Do I need special tools to install the valve?

Installation requires standard hand tools and a torque wrench. No specialized equipment is necessary beyond the basic tools used for transmission service.

How does the built‑in magnet improve transmission health?

The neodymium magnet captures metallic debris generated by wear, preventing it from circulating through the fluid and causing wear on gears and bearings.

Will the aluminum construction affect the valve’s weight?

The aluminum body is lightweight yet significantly stronger than the original plastic component, offering better heat dissipation without adding noticeable weight.

What warranty does Rogiera provide?

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