Less weight, more durability – what’s not to love? That’s what you get (and more) with ATI‘s new Vasco Inputs with lightweight drums for T400 transmissions. They’re 16 percent bigger than OEM T400 units and pair greatly with ATI’s billet aluminum Super Pump with bolt-in stator tube. See more details below.

Official Release:

Looking for the most performance from your T400? ATI now offers all new Vasco Inputs with lightweight drums for less rotating weight and improved durability. ATI’s “Big” Vasco inputs are 1-3/16” thick at the converter side and 1-1/4” where they press into the forward drum. That is 16% bigger than OEM T400 inputs and complement ATI’s Billet Aluminum Super Pump with bolt-in stator tube. Available with either an Aluminum Drum (Part #406003V) that comes with a steel center and can hold up to 8 clutches or an all-new lightweight Billet Steel Drum (Part # 406002V) with a new billet aluminum piston that accepts up to 9 clutches. For racers that need an OEM size input, ATI offers an OEM diameter Vasco Input (Part #406006) with a new Lightweight Steel or Aluminum Drum (406005) that is both stronger and lighter than OEM.
