Hello, I have a brand new 2019 Land Cruiser. I’ve put 1,300 miles on it. I noticed it sounded very tappy almost like a diesel when I was going through a drive through. I parked it and listened underneath. It sounds like it’s coming from the transmission pan area. I thought the transmission fluid might be low? The fluid is supposedly a “lifetime fluid”. Of course anything major would be under warranty. Just wanted to know if this is a common Land Cruiser 200 series thing or an unusual noise that I should address. Thanks in advance.
