The 2003 Toyota Tacoma requires Dexron VI Transmission Fluid and can hold around 4 quarts. Transmission fluid acts as a lubricant, protecting the transmission components from heat damage, similar to oil. Expect to pay about $80 to $100 for labor and $50 for parts when changing the transmission fluid on your Tacoma. It is recommended to have the transmission fluid replaced every 20,000 to 30,000 miles or every two to four years. Signs that it's time for a transmission fluid change include a grinding noise from the transmission, difficulty shifting gears, slipping during gear changes, sudden unexplained surges, and delayed movement after shifting into gear.

A 4x4 vehicle with automatic transmission only requires 2.1 quarts for a drain and fill, but a complete drain will need 10.4 quarts.

Firstly, who is suggesting that engine oil can be used as transmission fluid? And why are some saying it only requires 4 quarts, when the service manual clearly states it needs 5.5 quarts? I added 4 quarts following a filter replacement, but it only reached the dipstick. It seems like I need another 1.5 quarts to fill it properly. It's definitely not just 4 quarts, I have no idea where that information came from. Nothing on the truck seems to be just 4, except perhaps the tires or four-wheel drive system.
