Drain, Pan/Filter Service & Refill - Ford Ranger Maintaince And Repair Manual

If fluid is needed, use a funnel (to avoid spills) and add the required type and amount of ATF
5. If the level is below the lower mark, use a funnel and add fluid in small quantities through the dipstick
filler neck. Keep the engine running while adding fluid and check the level after each small amount.
DO NOT overfill as this could lead to foaming and transmission damage or seal leaks.
Since the transmission fluid is added through the dipstick tube, if you check the fluid too soon after
adding fluid an incorrect reading may occur. After adding fluid, wait a few minutes to allow it to fully
drain into the transmission.
DRAIN, PAN/FILTER SERVICE & REFILL
Transmission Fluid Pan and Filter
Under normal service (moderate highway driving excluding excessive hot or cold conditions), the
manufacturer feels that automatic transmission fluid should not need periodic changing. However, if a major
service is performed to the transmission, if transmission fluid becomes burnt or discolored through severe
usage or if the vehicle is subjected to constant stop−and−go driving in hot weather, trailer towing, long
periods of highway use at high speeds, fluid should be changed to prevent transmission damage. A preventive
maintenance change is therefore recommended for most vehicles at least every 90,000 miles (145,000 km).
Although not a required service, transmission fluid changing can help assure a trouble−free
transmission. Likewise, changing the transmission filter at this time is also added insurance.
1. Raise the car and support it securely on jackstands.
The torque converters on some transmissions are equipped with drain plugs. Because it may take some
time to drain the fluid from the converter, you may wish to follow that procedure at this time, then
come back to the pan and filter removal.
