If you own a Nissan with a CVT transmission, this replacement dipstick is a must-have for checking your fluid levels properly. It directly replaces OEM part numbers 31086-JA000 and 31086-JA00A, and works with a bunch of models including Altima (2008-2020), Maxima, Quest (2007+), Rogue (2013+), and others with Jatco automatic transmissions from 2006 up. The dipstick is about 23 inches total length and can bend slightly for easier handling. It's made from high-quality stainless steel with rubber components, following original factory standards for wear and corrosion resistance. To get an accurate reading, you'll want to start the engine and wait until the transmission fluid temperature hits about 80°C, then check without turning off the engine. Don't leave the dipstick in the tank after measuring though. Regularly checking your CVT fluid level can seriously extend your transmission's life by preventing overheating and damage from low or contaminated fluid. It's an easy DIY check that can save you from some expensive transmission repairs down the road!
