To check your vehicle’s fluid level, carefully re-enact these steps. First, park your vehicle in neutral. Then, look for the transmission dipstick; this is often located near the rear of the transmission and engine. Next, remove the dipstick, clean and wipe it thoroughly (Caution; Fluid May Be Hot), reinsert it again, and then pull it out. Now, observe the markings on the stick; A dipstick generally has two markings for full; one warm and one cold. Finally, if the fluid doesn’t reach the warm mark, you need to add transmission fluid to your vehicle.
