JS Professional Transmission O‑Ring Set USA Made

Description

Product Overview

The JS Professional Transmission O‑Ring Set is a precision‑engineered replacement kit for the 4L60E, 4L65E, 4L70E and 4L75E automatic transmissions. Manufactured in the United States, each set includes three multi‑sized input shaft O‑rings that cover every year, engine displacement and torque converter size for these models. Constructed from high‑grade nitrile rubber, the rings provide excellent resistance to heat, oil, and wear, ensuring a tight seal that restores proper hydraulic pressure and eliminates slippage.

Usage

These O‑rings are installed whenever the torque converter is removed for service, replacement, or upgrade. They are ideal for professional mechanics, DIY enthusiasts, and fleet maintenance shops seeking a reliable, OEM‑matching seal. By replacing the O‑rings, you prevent the common P‑1870 slip code, improve shift quality, and extend the life of your transmission.
