I recently flushed the cvt fluid on a 2020 mirage g4. About 2.5q came out and I filled with about same amount maybe 2.7q. Started went through gears then drove for a small drive and checked fluid and was perfect level. After about 2-3 weeks the cvt had a acceleration shudder then eventually stopped accelerating all together. I believe it failed. Used idemitsu n3 cvt fluid. Has 100k miles on car. Has anyone had this problem. Was it possibly something i did or didn't do?
