Description
Product Overview
The WnSEu Servo Piston Kit is a precision‑machined replacement for the original servo in GM 700R4, 4L60, 4L60E and 4L65E transmissions (model YX04343-5). Constructed from hardened steel with a machined exterior, it offers superior holding power for high‑performance applications. Weighing just 1.46 lb and packaged in a compact 6.42 × 5.94 × 3.62 in box, the kit arrives ready to install with no additional assembly required.
Usage
Designed for both daily drivers and performance enthusiasts, this servo kit fits transmissions built between 1982 and 2014. Whether you’re upgrading a street car for smoother shifts or reinforcing a race‑ready drivetrain, the kit installs directly into the existing housing—no need to drop the transmission. Ideal for mechanics, DIY owners, and professional shops seeking a reliable, bolt‑in solution.
Why Choose Us
WnSEu combines rigorous engineering with quality manufacturing. Each kit undergoes dimensional inspection to guarantee a perfect fit, and the machined surface reduces wear compared to stock components. By firming up shift feel early in the transmission’s life, the kit helps prolong overall durability and reduces the risk of costly failures.
