Now heres one thing u heard recently and didnt try doing it and kinda sounds crazy but maybe logical at the same time idk so i wanted to know your opinions about it.

So basically its advices when you are in a traffic. Put your auto transmission in manual mode. This way you basically lock it on first gear and it could help the life span of the transmission. The idea is that sometimes in traffic if you start to pick just a bit of speed most auto trans will go for second gear ans then you stop and basically upshift and downshift for no reason so you could lock it in first gear therefore no more unnecessary gear change
