Whether you’re replacing a transmission on your daily driver, starting a build, or looking to take your street/strip ride or drag car to the next level, Summit Racing automatic transmissions are a budget-friendly way to send power to the wheels. Summit Racing automatic transmissions are available both all-new and remanufactured, each packed with quality components and dyno tested for trouble-free performance right out of the crate. Choices include a wide range of popular GM and Ford transmissions, including GM TH-350, TH-400, TH-700R4, 4L60E, 4L80E, and Powerglide, plus Ford AOD. Pick a transmission with the right bellhousing to bolt up to your engine, or choose a TH-400 or Powerglide with no bellhousing, so you can use an aftermarket bellhousing to adapt it to a wide range of engines. Got a four-wheel-drive truck or SUV? Summit’s 4WD-specific 4L60E and 4L80E transmissions come ready to bolt up to your transfer case.

Remanufactured Transmission

When you choose a Summit Racing remanufactured transmission, you get all-new clutches, thrust washers, seals, gaskets, bushings, and bands, as well as upgraded parts to address common failure points. The pump and valve body are rebuilt, with valve bodies tuned for improved performance and firmer shifts. It’s a better-than-new transmission at a price that will leave money for the rest of your build!

Race-Ready Performance Automatic Transmission

Summit Racing Performance Transmissions are a line of TH-400 and Powerglide automatics that are upgraded to hit the track behind high-horsepower engines. These high-performance automatics step it up with features like high-strength, 300M alloy steel input shafts, high-volume pumps, recalibrated full-manual trans-brake valve bodies, billet aluminum drums, billet steel clutch hubs, 36-element pro-mod sprags, and more.

FAQ section:

Q. What transmission works best for my build: street, strip, off-road, or towing?

A. For mild street use and daily driving, any of Summit’s standard-duty automatic transmissions are a great choice and will provide many miles of smooth, reliable service. For street/strip or drag racing applications, step up to a Summit Racing Performance TH-400 or Powerglide transmission. They’re built to take the high power levels and abuse of drag racing, and include features like manual valve bodies and trans-brakes.

If your vehicle is used primarily off-road or for towing, consider a TH-400 or 4L80E. These are beefier transmissions that can handle the strain of off-road use and heavy loads. For occasional off-roading and lighter towing, any of Summit’s automatic transmissions are suitable, though an auxiliary transmission cooler is recommend (a transmission cooler is a great addition that will prolong the life of any automatic transmission).

Q. What are the types of automatic transmissions?

A. The most common type of automatic transmission is the conventional torque converter automatic. This encompasses everything from the classic 2-speed GM Powerglide and 4-speed GM 4L80E, to newer transmissions like the 8-speed TorqueFlite used in Mopar and RAM vehicles, and the 10-speed Ford 10R80 used in the Mustang and F-150.

Additional automatic transmission variants include DCTs (dual-clutch transmissions), which are essentially automated manual transmissions, and CVTs (continuously variable transmissions) which employ a set of variable-diameter pulleys to create a continuous range of ratios without the fixed steps common in other transmissions.

Q. How do I know what transmission I have?

A. Often, transmissions have external markings on the case or pan that will provide identification. Also, searching “transmission dimensions” in the Help Center at SummitRacing.com can help you narrow it down.
