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.
Upgraded steel shift cables
6 speed shifter assembly w/adapter bracket and shift knob/boot.
ZZP CV Axle shaft assembly
ZZP Billet aluminum transmission brackets (Top and Rear)
ZZP Intermediate "jack" shaft w/custom speed sensor tone ring
ZZP Billet speed sensor bracket
ZZP Speed sensor extension harness
Cast transmission bracket
Solid shift cable bracket (Replaces Saab dampened bracket)
I have an automatic hhr ss will it be possible to do a swap with this kit?

So it's much more simpler to do in in a standard transmission car?
Answer by: Matthew Hudobenko on Mar 24, 2016 3:06:01 PM
Yes, it's possible. Very labor intensive requiring custom work and removing the dash entirely. We have done it for a few customers. Labor for a standard F35 to F40 swap in a stick car is $1000, going from auto to stick we charge 40 hours. In addition you need a new engine wiring harness, body control module and brake control module from the proper year of manual vehicle.

Why is the gearing of a +11 regal f40 not optimal as opposed to 2007+ Saab f40?
Question by: Ryan Spiers on Jul 16, 2016 3:28:00 PM
The 07+ gearing is preferred because it has a more aggressive final drive ratio as well as 3rd through 6th gears. The truest reason most actual reason a Saab transmission is required is extremely simple. The Saab F40 is designed with the GM Ecotec Bell-housing pattern. Where as the F40 transmission from the Buick and Pontiac lines are designed with the GM V6 Bell-housing pattern.

the older trans has a 'sportier' gearing, and is better suited to a performance application.

No, this kit is the conversion kit that allows customers to replace the whole F35 transmission with the superior F40 Getrag. This is not the quaife replacement kit that uses the case for the F35 still.
