F40 6 Speed Conversion Kit

F40 6 Speed Conversion Kit


Availability: In stock

Product Description


    6 speed conversion for your Cobalt/HHR!  It is based on GM's F40 transmission, this conversion solves all of the F35 shortcomings with higher power capability & smoother shifting!  The F40 transmission has 2 internal shafts instead of one, the gears are twice the size of the F35, and it has an additional over drive gear.

    This kit will require all of the parts from the list, you will not be able to reuse any of your F35 parts, i.e. flywheel, clutch disc or aftermarket shifter.  The included dual mass clutch assembly will support up to around 450hp.  However we do have a F40 Race Clutch option that will replace the flywheel/disc/pressure plate that is included with this kit.

    Requires 2007+ Saab transmission and PCM reprogramming to adjust for the new speed sensor.   Will not work with G6 or '11-13 Regal F40, it does fit pre-2007 Saab F40 but the gearing is not optimal.  Please don't ask if it will work with XX transmission. It's designed for a Saab trans as stated above and nothing else.
