Adding Additional Transmission Fluid

WARNING: This page is about a different car, the 2013 Ford Mustang. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: To get an accurate transmission fluid level reading the engine should be idling (600-750 rpm) in PARK.

Install the Transmission Fluid Fill Tube into the transmission fluid fill hole.

Use a Rubber Tip Air Nozzle to apply a maximum of 206.85 kPa (30 psi) to the open end of the vacuum/pressure hose from the Transporter Fluid Evacuator/Injector. Transmission fluid will immediately start flowing out of the Transporter Fluid Evacuator/Injector into the transmission.

NOTE: Do not overfill the transmission. The transmission fluid level must be at the upper level of the crosshatch mark.

Reinstall the transmission fluid level indicator only back into the transmission fluid fill plug hole to check the transmission fluid level. Repeat this until a consistent reading is established.
