Sequential shifter : T56 GM

$2,650.00 AUD +GST (Gst is only applied to Australian orders)

A bolt on sequential shift conversion for the Tremec t56 gearbox. Faster more consistent shifts while retaining a factory gearbox.




The T56 is one of the strongest manual transmissions available in a production car. Mechanically these are a great gearbox the internals are strong and reliable their only downfall is shifting. The shifting issues experienced most often aren’t caused by the gearbox its self but from the difficulties shifting cars under the high acceleration loads experienced from the powerful engines they are used with. This is exactly the reason almost all dedicated race gearboxes use a sequential shift action. This Sequential shifter solves these issues by converting the H pattern shift to sequential pattern.

We designed many different methods to do the sequential shift conversion and decided that a purely mechanical solution was the only way to go this not only ensures reliability but it gives the driver the raw feedback that is required. The shifter bolts onto a standard gearbox with no modifications and does not need any electronics to function. This is the second version of this product and has a few small tweaks including more extensive use of aluminum for a significant weight reduction, the lever angle can now be easily adjusted by the owner and reverse is now selected by a lever.

Which gearboxes will this version fit?

This version is to suit what would be considered the early GM t56 cars and include the gearboxes from:

  • Vx - Vz Holden Commodore 
  • 4th gen Camaro/Firebird

Dimensioned drawings are available for you to check compatibility. Keep in mind that we sell shifters to fit gearboxes not specific cars so tunnel modifications may need to be made to fit your car.
