Build your own transmission? You will not find better quality or value anywhere.

Beware of inferior parts packaged in pretty boxes. These kits contain the parts we use in our Competition and Super Comp transmissions.

Performance Automatic assembled these
kits from over 20 years racing experience. A premium seal and gasket kit complemented with Alto high performance bands, Alto racing clutches, bushings and various internal
parts combine to give the winning edge round after round. These kits do NOT include valve body kits. They are available separately.

Keep your transmission in the hunt with these filter and pan gasket sets.

Often neglected, these service kits are great to use between weekends at the track. High flow filter combined with a Durapreme gasket make changing transmission fluid a snap.

Keep a spare kit in the garage or trailer for that critical time you need it the most.
