Swap Block™ Mock Up 6L80E 6L90E Transmission | GF-MUT-6L80

Years: 2005-2016 Transmission: 6L80E, 6L90E Our patent-pending tab-and-slot version of the mock up transmission block provides accurate transmission mounting, shifter location, and yoke positions. This unique design is lightweight and comes disassembled for ease of shipping and storage. One tool accomplishes accurate placement of either a 6L80E or 6L90E transmission depending on the position of the rear plates. Easily positioned by hand, there is no need to bench-press a heavy transmission into place for fitment and fabrication of crossmember, etc. Save time and money and work more safely. Durable steel construction resists heat from welding, so unlike foam blocks, custom crossmembers can be fabricated close to the block. Download Assembly Instructions here.
