I spent around 310 dollars doing oil change, ATF fluid drain and fill and rear diff drain and fill by myself.

I was quoted 300 plus tax for a single drain and fill for the ATF fluid only.

I got 4 quarts of Toyota ATF WS fluid, crush washers, cheapo OBD2 Bluetooth scanner which I got to read transmission fluid temps (104 to 113 farenheight) after some fiddling. $110

3 quarts of GL-5 fluid for rear diff with Toyota crush washers. $100

10 quarts of 0w-20 full synthetic engine oil, tool to remove the filter housing, crush washers, and Toyota filter. $100

I called the dealership and they quoted 1200 for doing all of this. No thanks.
