This may be a stupid question, but I am new to automatics. Does leaving my car in D vs D(with square around it) mean that the car will not shift into fourth gear, and only use the first 3 gears? I am confused
Ok you have 4 positions for forward gears the first one you come to after neutral has 1-2-3-4 and id ussually marked D or OD, The next back has 1-2-3 and is marked 3 OR D so if you mean this one then yes you would only have three gears.
Hope this helps
