How-To: Remove Clutch Delay Valve (CDV)
Overview:
Hello everyone and welcome to my first "How-To" ever. If you are clicking this you are probably looking for a solution to the common and quite annoying first to second grind in the M32 Manual transmission. Some people are reporting a grind from second to third and/or a grind from third to fourth, although less common the problem is still present and can make daily driving quite annoying. If you want to read more about as to why the grinding is present and other common problems with our manual transmission check out "XtremeRevolution" write up, that can be found here --> http://www.cruzetalk.com/forum/10-gen1-powertrain/36617-cruze-manual-transmission-m32-issues.html. Many users have reported (Myself Included) that changing the transmission fluid to AMSOIL Syncromesh Manual Transmission fluid has helped not only the 1-2 grind but making shifting through all gears smoother. AMSOIL Severe Gear 75w-90 is also recommended if you are tuned and/or for more "spirited drivers". I would recommend doing that first or at the same time as removing the Clutch Delay valve (CDV). A good write up on how to do that can be found here --> http://www.cruzetalk.com/forum/129-...627-how-change-manual-transmission-fluid.html.
The CDV is designed for less experienced drivers to help provide a soft/smooth clutch engagement. It makes the clutch easier to push in but engages the clutch slower and with less force resulting in slightly more clutch wear and a "grinding" feeling when trying to shift fast. It has it's benefits to new drivers but can be annoying to more experienced drivers who like to have a stiffer clutch and to shift fast. I have had the CDV removed for around 5000 KM with no bad effects and it is super easy to remove and costs nothing. It is one of the best "Mods" you could do to your Cruze. Lets get on with the removal...
Tools Required:
- A Blade Screwdriver or Butterknife or Pick or if all else fails Fingernails.
- Recommended but not required- Wheel Chocks
Procedure:
Park on flat level surface, set the parking brake and chock the wheels.

Pop the hood and look between the the engine and the battery. Between the charge pipes.

The hose connects to another plastic piece coming out of the transmission, on the end there is a "valve" to bleed the transmission fluid. That will be called the top of the "T" The bottom of the "T" will be the hose. Note, the following image was taken from underneath the car:

Between that hose and the top of the "T" will be the CDV.

On each end of the CDV will have a clip that needs to be pulled out, careful the can pop and shoot out and are easy to lose. Just be careful prying them out with a small screwdriver.

Once you remove each clip you can pull the CDV from the top of the "T" and remove it from the hose, installing the hose directly into the top of the "T" and install the clip. I don't have a picture of this because I have already done this procedure and did not want to install just to remove it again. If you need more help let me know and I will.
That's it, you are done. Take the car for a drive and after a few shifts it will be stiffer and you will notice less or no grind when shifting. You do not need to bleed the clutch during this procedure.
Enjoy the benefits of the quick and easy "mod"
