Checking the Transmission Fluid
# It is important to check the fluid level only after the fluid has circulated throughout the transmission by shifting through the gears. Failing to allow the fluid to circulate will result in a false fluid level reading. Turn the engine on and shift through each of the transmission's gears with the brake pedal depressed and the parking brake applied. The car should be allowed to idle in each gear position for approximately five seconds. Turn the engine off, then climb underneath the passenger's side of the vehicle. A small plug is located on the passenger's side of the transmission. Remove this plug with a wrench. Turn the engine on and observe whether any fluid drips out of the transmission plug's opening. If fluid does begin to drip from the plug opening, the transmission does not require additional fluid. Turn the engine off and install the transmission plug.
