BD's TapShifter adds fingertip shifting to the 2003-2005 Duramax Allison 1000, like the newer trucks have, for passing, pulling and climbing hills.
Inside the box: a control module, a shift lever that comes pre-bent to fit well, and wiring that plugs into the factory connectors so nothing gets spliced.
Owners of 2003-2005 Duramax trucks who tow and want more control over gear selection.
