Complete bolt up 4R70W Street Smart transmission packages for all Ford engines.

At Performance Automatic, we've been modifying Ford transmissions for over 35 years. No one builds more, no one builds better.

Our C4's and C6's can handle gobs of power year after year. Only the best components are installed to provide years of performance driving.

Our AOD transmission is a proven winner when it comes to non-computer
controlled 4 speed overdrives.

Upgraded internals like an extra
wide overdrive band, diode sprag and extra 3-4 clutches combined with a shift improvement package make this an
excellent swap into an earlier Ford. Dyno tested and given Lifetime Warranty when purchased in the
PASS53103 Street Smart Package these
units are perfect as a replacement
on any Fox body or restomod.
