Description Shipping information Reviews
  • Our patent-pending tab-and-slot version of the Swap Block™ Transmission Mock Up Block provides accurate transmission mounting and yoke positions.
  • This unique design is lightweight and comes disassembled for ease of shipping and storage.
  • One tool accomplishes accurate placement of a 4L80/4L80E transmission found in 1991-2013, 3/4 ton trucks and vans.
  • 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.

Our video and written assembly instructions describe how to assemble the LS version of our Swap Block Engine Mock Up Block. Assembly with our patent-pending tab and slot system is the same for our engine and transmission Swap Blocks.
