F40 6 Speed Conversion Kit

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. As of 11/2020 we now include an F40 race clutch and Fidanza aluminum flywheel in the kit, this clutch and flywheel combo will hold whatever power you intend on making. Do not be fooled by competitors kits, their kit requires you to purchase a clutch separately.

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)

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.

Good product but a little to expensive.

This kit its more expensive than what our car its worth it(little expensive),if you love your car or its a project one those are a good product but needs to have more information about installation. You have to figure out which bolt goes to where, and a very important one, (clutch wires). But a smart one will figure out before ZZP reach you with an answer.

F40 swap kit

Was shipped a defective half shaft with the reluctor wheel in the wrong location. No response from zzp customer service regarding this issue until I was advised to direct it to a person's email at zzp. The outcome of the part was some reimbursement which only covered half the cost to have the part fixed. The other outcome was to remove the part making the car non drivable for weeks to have them correct the part. No instructions included with the kit. Had to get these from another source. The instructions are outdated as the parts in the pictures aren't the same as sold in the kit. On several descriptions they use "use the hardware provided" but all hardware was put all in 1 bag for the whole kit. Ended up mocking up the kit on the bench and guessing the placement of the hardware. Other then that the kit is installed and is working. For the price this should be put togther better.

F40 swap

Everything is really smooth the kit is well put together and definitely worth the price only thing that isn’t included is a few bolts for the top transmission mount but those are easily found at a local hardware store. Kit bolted up pretty easy with very little modifications and if you are like me and have the ldk swap it makes installing the kit a little bit easier. Honestly I wish the lnf cobalts came with this transmission because of how much smoother and easier it is my car has every bolt on but 3 bar map sensors and it drives like a stock car. My car is pretty low and I used a trans mount spacer and I installed steering rack spacers and I can’t hear any creeks or binds that some people say they have experienced. I also have the upgraded mounts from zzp which make the transmission feel great ( I am used to poly mounts I don’t care about the added vibrations). If you are debating building an f35 trans or buying this kit without a doubt I would invest in this kit if you like your car and plan on keeping it long term. I haven’t installed it yet but I feel with the short shift mod the shifter will feel perfect it’s very smooth and has a pretty decent weight to it. Only recommendation is have time and patience when installing this kit and stay organized and it will go pretty smooth for the install.
