Let’s be real honest here, dropping in an automatic into your build seems like the easier option, right? There’s no wrestling with the shift linkages; hunting down a pedal assembly; and then there’s having to modify your floorboard. But what if all of that was simplified and prepackaged for you? And it promised modern performance and a clean, trouble-free installation without requiring a second mortgage?
That’s exactly what American Powertrain offers builders of every ilk and skill set. Got a pretty straight E-body Challenger that you’d like to keep the factory shifter location through the center console? They’ve got it. Building a rowdy A-body Swinger for autocrossing at Goodguys? Guess what? American Powertrain has everything for that too. And yeah, their tech team will walk you through each step of the way if you need it.
In a recent Facebook post, American Powertrain wrote: “So you got yourself a Tremec Transmissions TKX or Magnum but what do you need to do to make the shifter come out in the right location for your musclecar or truck? This is where American Powertrain comes in with different mounting location options, offsets, even transmission mods to make sure the shifter is right where you need it.”
In the video below, AP’s Matt Graves walks you through their shifter options, how American Powertrain can precisely modify any Tremec to fit your particular application, and how their lineup of shifters place the power back into your hands – which we all know is a lot cooler and fun to drive than some sloppy slushbox.
