Although a CVT is a type of automatic transmission, the method for checking this fluid varies.
CVT Fluid Types. If the recommended CVT fluid is a proprietary formula, specific to your vehicle’s make and model, you may have to buy it from the dealer. If you take your vehicle in for service, make sure the recommended CVT fluid is added. Do not assume that standard ATF is adequate for a CVT.
Checking/Adding CVT Fluid. Some CVTs have a dipstick, some have two plugs, while others have three plugs. If your CVT has plugs instead of a dipstick, you need to find the fill/level plug. On plug types, the fluid should be level to the bottom of the plug hole threads. Review the owner’s manual or contact the dealer for fluid checking and filling instructions.
