The 2006 Ford F-150 rear differential fluid capacity iS6.9 quarts. The transmission fluid needs to be replaced every 30,000 to 60,000 miles. Along with fluid changes, terrible sounds will come from the transmission. Old transmission fluid will be awful to the ear. A worn out torque converter will cause a headache. The transmission is one of the most critical parts of the vehicle. You will face issues at some point. If the transmission fluid leaks, that needs to be solved quickly. Delayed shifts can cause acceleration issues. The transmission may slip. You might experience shudders. Hard shifts may arise and that is no good. There could be jerking. The gears can become stuck.

The rear differential on a 2006 F150 takes about 5.5-6.9 PINTS. I use 75-140 synthetic. That's about 3 quarts.
