Trans-Scat ® Valve Body Kits
The Trans-Scat® Kit offers two options for applications.
The Trans-Scat® eliminates transmission
slippage and lag. Provides a harder,
more positive shift and allows you to
downshift the vehicle on demand. With
most models, you are able to manually
shift and hold the transmission in first
gear until you shift to a higher gear. As
long as the vehicle remains in drive, it
will still be fully automatic. This kit vastly improves the 2nd
and 3rd gear shift.
