So I have a 2014 prius C. The car has 76k on it. I decided to change the transaxle oil. Bought 4 qts. of Toyota WS trans fluid. A fluid pump. ran the car up on ramps and drained the transaxle. I got three quarts out of it. I jacked up the back and pumped in 3 + a bit qts before it rand out of the fill hole. I thought the TA took 3.5 qts? I put in what I got out and it ran out of the plug so it must be OK. Thanks for any help.
