About Jordan Hanth

"Transmissions are the specialty. Simple as that."

I'm Jordan Hanth, owner of Super Specialty Ltd. — SuperSpec.RS, Super Specialty Race Service. I build Ford and GM 10-speed automatics, the ones in your Mustang GT, F-150 and Camaro.

The approach is pretty simple: build what makes sense.

Every setup is different. Whether it’s a basic refresh or a performance build, the first step is understanding what you have, how you use it, and where you want to go with it.

Sometimes more upgrades make sense. Sometimes they don’t. The focus is always on getting the build right, not making the bill bigger.
