Description Shipping information Reviews
  • 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.
