Q: Switch to Manual mode, but gears don't seem to change any more in that mode.
I drive a 2010 Nissan Altima with an automatic transmission, but frequently use the manual mode. (I don't abuse it) Normally, when I shift over to manual, "D's" come up to on my dash (I think this means "Drive Shift" or "Synchro") and if I shift up or down it will respond by putting me in an appropriate gear and going up or down. Now, when I try to change to Manual mode, it just stays in drive. No "D's" or gears show up any more. It doesn't respond at all when I try to change to manual mode. What could be the problem?
