The 2010 Chevy Malibu, like many modern vehicles, doesn't have a traditional dipstick for checking transmission fluid. Instead, the transmission fluid level is checked by a technician using a specialized scanner tool that reads the fluid temperature and level from sensors within the transmission. There's no DIY method for accurately checking the transmission fluid level in this car.
Attempting to check it yourself could be damaging and inaccurate. If you suspect a problem with your transmission, such as slipping, unusual noises, or difficulty shifting, you should take your Malibu to a qualified mechanic or a Chevrolet dealership for diagnosis and service. They have the proper equipment and expertise to properly assess the transmission fluid level and condition.
