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 an option for this kit. Do not be fooled by competitors kits, their kit requires you to purchase a clutch separately.

Includes:

  • Upgraded steel shift cables
  • 6 speed shifter assembly w/adapter bracket and shift knob/boot.
  • ZZP Billet aluminum transmission brackets (Top and Rear)
  • ZZP Intermediate "jack" shaft w/custom speed sensor tone ring (Saab trans only)
  • ZZP Billet speed sensor bracket (Saab trans only)
  • ZZP Speed sensor extension harness (Saab trans only)
  • Cast transmission bracket
  • Solid shift cable bracket (Replaces Saab dampened bracket)
  • Dual mass clutch and flywheel (which is not included in our competitors kit)
  • Flywheel bolts
  • Bolt pack for mounts
  • Optional: Driveshaft Shop stage 2 CV axle shaft(s)
  • Optional: new F40 "Regal" transmission
    How to order your F40 conversion kit:

    What engine do you have? This option determines what axle is included in the kit. (LNF has a larger outer spline than the LSJ/LE5)

    Transmission: This determines if you have a transmission already, which one you have if you do, so we can include the correct trans mounts with the kit.  If you need a transmission, then this option allows you to add a new "Regal" transmission.

    Axle(s): You will need at least one shorter (driver side) axle to use the F40 transmission.  If you already have one, then this option removes any additional axles from the kit, or if you want just the required one, this allows you to add it, or if you want a matching pair of the upgraded Driveshaft Shop axles, you can add both sides.

     

    Requires Saab 9-3 ('07+ preferred for best performance gearing) or 2011-13 Regal 6 speed F40 transmission and PCM reprogramming to adjust for the new speed sensor.  It does fit pre-2007 Saab F40 but the gearing is not optimal.  The Regal transmission has poor gearing for drag or road course cars (wide gears, tall final drive), but can be useful for half mile racing.  Please don't ask if it will work with XX transmission.  It's designed for a Saab or 11-13 Regal trans as stated above and nothing else.

    These kits are built per order and can take up to a week to be packaged and shipped.

      F40 conversion project

      The time and thought that ZZP put into making this kit work in these cars is incredible. The staff at ZZP were there every step of the way during my install. When I had questions they got right back to me quickly. If I could I would like to shake the hand of everyone there at ZZP as I can not thank them enough. They run a top notch company. I have dealt with them with other mods to my car and the experience I've had is beyond 5 Stars. I had an F35 with the 4.45 gears and I did enjoy it. Tonight was the first time I took the F40 for a ride and the difference is night and day. The F40 is so smooth I feel like I'm driving a new car. I am using the stock clutch because I didn't want to hear the chatter associated with the single mass racing flywheel and clutch. According to ZZP staff they claim it can hold approximately 400whp and since I am only at 354whp I am giving it a try. I also installed a Quaife LSD which I did myself and was very easy to do. Final drive is now with the F40 is 3.545. This conversion with everything I did was a bit pricey but it was worth every penny. If your on the fence about doing this, I say do it because you are going to love your car even more! Next to installing the ZFR 6758 this is the best mod yet!

      6 Speed

      Very nice well made product not hard to install. The transmission is way better than the 5 speed. On mine I added a quife differential and made it a LSD. With my last set up ZFR 7163 470 whp it lasted and worked just fine :) my old 5 speed broke when I had in the 6758 at 400whp. The kit is amazing the transmission is an excellent upgrade from the original. The down side is the noise OMG every one thinks your car is broken!! it is embarrassing to drive the car :( the clutch design is made that way and there is no way of fixing it. When the A/C is on the noise can be heard from 50 feet away and it is even worst. Love the feel of driving it hate the noise it makes.

      Great kit!

      This is a rock solid kit with everything but the transmission. I just finished my install two days ago and so far its doing great. I used Redline MT90 trans fluid as recommended, the F40 is a little clunky when cold but warms up quick and shifts buttery smooth. I do recommend installing a new throw out bearing and axle seals for the used transmission. ZZP has great tech support!
