Whether you’re building a race car, a high-performance street machine, a tricked-out pickup, or even a numbers-matching restoration, Summit Racing Equipment has the TH400 shifter for your ride. GM’s TH400—or Turbo 400, as it’s often called—is a hugely popular three-speed automatic known for its durability behind high-horsepower engines. Introduced in the 1960s, it was commonly found in muscle cars from Chevy, Pontiac, Oldsmobile, and Buick, as well as GM trucks and SUVs. Today, it’s still the transmission of choice in many applications where strength and performance are top priorities.

Often, stock shifters are worn out,...

Often, stock shifters are worn out, sloppy, or just not great for high-performance use. An old column shifter might be fine for cruising, but it just gets in the way and causes missed shifts when the going gets twisty or you’re trying to bang through the gears—not ideal.

Summit Racing carries every popular style of TH400 shifter. Ratchet, detent, and gate-style shifters promise quick, precise shifts, especially in the heat of competition. Many are equipped with NHRA/IHRA-approved reverse lockouts, neutral safety switches, and reverse light switches. There are case-mount and floor mount options, which can be installed in conjunction with a mounting bracket. Look for a style of shifter that’ll work (and look!) great in your application, and keep an eye out for features like buttons for line lock and nitrous activation.
