How to Add Manual Transmission Fluid Here is how to add fluid. See Recommended Fluids and Lubricants on page 6-13 to determine which type of fluid to use. 1. Remove the filler plug. 2. Add fluid at the filler plug hole. Add only enough fluid to bring the fluid level up to the bottom of the filler plug hole. 3. If your vehicle is a CTS, replace the gasket and reinstall the filler plug. If your vehicle is a CTS-V, apply LOCTITE ® #516 or equivalent sealant to the threads and then reinstall the filler plug. Again, with either vehicle, be sure the plug is fully seated. When to Check and What to Use The hydraulic clutch fluid reservoir cap has this symbol on it. See Engine Compartment Overview on page 5-12 for reservoir location. Hydraulic Clutch It is not necessary to regularly check clutch fluid unless you suspect there is a leak in the system. Adding fluid will not correct a leak. A fluid loss in this system could indicate a problem. Have the system inspected and repaired. Refer to the Maintenance Schedule to determine how often you should check the fluid level in your clutch master cylinder reservoir and for the proper fluid to use. See Owner Checks and Services on page 6-9 and Recommended Fluids and Lubricants on page 6-13. How to Check and Add Fluid Make sure the fluid level is at the MIN (Minimum) line on the side of the reservoir. If it is not, remove the cap and add the proper fluid until the level reaches the MIN line. 5-27
