While it is not uncommon for new cars to have 7-speed or greater transmission offerings (evenCompatible with Ford and GM share a 10-speed auto!) the majority of manual trans swaps happening in the muscle car and hot rod arena are still the ever popular 5-speed. This is mainly due to cost and fitment, with a lot of applications having complete swap kits available for the popular Tremec line of 5-speed manual transmissions. But many of us want more. More torque capacity, more overdrives, and more gears, even if it means a bit more cost and having to deal with some fabrication for the install. Using mock up transmissions are a real back saver in these cases where you’re installing Tremec’s T-56/Magnum/TR-6060 family of 6-speed manuals. Traditionally, building something with a transmission that was never meant to be installed in it would require the actual transmission, a floor jack or transmission jack, and a spotter or two keeping things in check while measurements were taken, parts tack welded, and so forth. It’s not an easy or quick process, and it can be dangerous with a 150 pound transmission being carefully balanced on a floor jack
