Rebuild Kit, High-Horsepower GT3 Master

The Goerend 48RE GT3 high horsepower master rebuild kit should only be installed in competition vehicles with 1000+ HP. This kit includes all the parts needed to update and rebuild a working transmission. This kit includes a billet 4-seal front servo piston kit, billet front band, rear servo apply rod, billet rear/forward clutch apply piston, low reverse and front planetary thrust washers not included in the GT2 kit. We use the best OE parts, performance aftermarket parts and build our own parts in all Goerend rebuild kits. This kit is intended for a professional transmission technician who has proper equipment to clean, inspect, test, and rebuild a transmission. Goerend Transmission is not a technical or training service. Customers of this kit are expected to have access to and be proficient with necessary equipment such as scan tools and pressure gauges. This kit does not include every part that may need replacement.
