Overview

The GForce GF-MUT-6L80 is a transmission swap block designed for fabrication and fitment of 6L80E and 6L90E transmissions. It provides accurate mounting, shifter location, and yoke positions for model years 2005-2016.

This tool is lightweight, comes disassembled for shipping and storage, and can be positioned by hand, eliminating the need to bench-press a heavy transmission. Its durable steel construction resists welding heat, allowing for custom crossmembers to be fabricated nearby.
Show original supplier description
The GForce GF-MUT-6L80 is a patent-pending transmission swap block engineered to simplify the process of fitting 6L80E and 6L90E transmissions into vehicles from model years 2005-2016. This innovative tool accurately establishes transmission mounting points, shifter location, and yoke positions, crucial for custom fabrication projects. Its unique tab-and-slot system allows for manual positioning, removing the labor-intensive step of maneuvering a full transmission for mock-up purposes. This not only saves time and money but also enhances workshop safety. Constructed from durable steel, the Swap Block is built to withstand welding heat, a significant advantage over foam blocks. This resilience enables fabricators to work on custom crossmembers in close proximity to the block without compromising its integrity. The natural metal finish ensures a robust and functional tool for various custom builds.
