Transmission:    AOD - 450

The first level of performance at SPT is the AOD-450.  We consider it an improved alternative to a stock replacement.  It is fully rebuilt using AOD cores we have available.  Each unit is fully inspected for wear, all gaskets and seals are replaced with quality new pieces, and final clearances are adjusted for performance use.
