SEMA 2013: ATI’s T400 Transmission Offerings, Trans Fluid, C7 Damper

The Powerglide parts are starting to dry up and the T-400s are right behind it, so we are building as many new parts for these transmissions as possible

“The Powerglide parts are starting to dry up and the T-400s are right behind it, so we are building as many new parts for these transmissions as possible, JC Beattie Jr. of ATI Performance Products. One of those new parts is their new billet aluminum pump. The finished pump features a three piece design with bolt-in, one piece, heat treated alloy steel stator tube for improved fluid routing over the pressed in OEM or aftermarket tubes. At just 12 pounds, the pump is five pounds lighter than the OEM unit. An adjustable pressure regulator is also included.

Also a new part out of necessity that’s been improved over the OEM counterpart is their billet aluminum valve body. “The billet aluminum valve body is lighter than anything steel with simple, and really short passage ways,” says Beattie Jr. “This allows the transmission to shift really quick, especially off the transbrake.”

 New Super F ATF Fluid

In conjunction with Driven Racing Oil, ATI has developed their second version of their popular automatic transmission fluid. “A lot of the high horsepower turbo and supercharger guys are burning up the 20 weight fluid,” says Beattie Jr. “The new 30 weight fluid helps that and even tightens up the converter.”

Some features include:

  • Faster clutch engagement
  • Firmer shifts
  • Lower temperature base
  • Foam inhibiting
  • Fully synthetic for long life
  • 30 weight designed for high temperature supercharged and turbo applications
