I recently purchased an automatic 2016 Scion tC with 94k miles, and wanted to exchange some of the transmission fluid. I followed Scotty's directions in one of his videos, but I'm afraid I may have either put too much or too little fluid. About 1.5 qts came out of the drain plug, and so I pumped 1.5 qts back in (Toyota WS Fluid), but the fluid didnt start trickling out when it was full like it did in Scotty's video, so I put about .25 qts more in before I stopped. Transmission shifts totally fine, nothing feels off at all, but I believe my engine or transmission is making kind of a mild squeaking sound when Idling in Drive or moving slowly. Help put my mind at ease. Thank you!
