ACP Motorsports / Trans-Am Series / 6 Wins 2019 = 5XD! “The 5XD sequential gearbox is the smoothest shifting, most reliable, and trouble free racing transmission I have ever had in any race car I’ve driven in. Today’s high HP racer needs a durable transmission with a less aggressive starting line ratio. Most racers achieve this by converting the Turbo 400 transmission to a 2-speed unit allowing them the ability to leave off the transbrake in 2nd gear. ATI now has an answer for this market and offers three variations of a 2-speed Turbo 400!

Race Transmission Dump Valve

John Kilgore Transmissions offers a new three-speed racing automatic that's stronger, lighter and quicker than a C4 and less power-robbing for quicker ET's. This light weight transmission is based on the legendary Turbo 400 but has been redesigned with super lightweight internals to reduce drag and speed-up shifts. The key is in the direct drum that weighs a full five pounds less than a C4's and 15 less that a C6. Though dramatically lighter than the C6, Kilgore's transmission offers as much or more capacity. 5.0 Mustang race application is a snap with the available small-block Ford bell-housing.

Drag Racing Transmission Builders

In the Superlite transmission the forward & direct clutch assembles are in one housing, and always rotates with engine RPM. The complete housing assembly weights just 12 pounds and with aluminum steels it can weight as little as 9 pounds. That means it takes far less horsepower to run the transmission, so more power is available for acceleration. This is not rocket science! Less energy used by the transmission and more energy is available to the rear wheels!
