I have the Mazda CX-5 with the automatic transmission. This automatic locks up the converter after 5 mph and operates like a automated manual throughout the 6 gears. it feels a lot like a manual transmission in its direct feel and the RPM coincide with vehicle speed instead of throttle position. I know in some modern manual transmission equipped cars the computer will shut off the fuel to the engine when the car is coasting in gear to save fuel. Does anyone know if that could be true for a vehicle like the Mazda CX-5? I'm afraid to let it coast in neutral and put it back in gear while the car is moving for fear of damaging the transmission or causing excessive wear. 6th gear is so tall though that is coasts really well in it. Also new to this site, great information here. Just starting using the techniques I'm learning here for about 90 miles now (from 1/2 tank) and my AVG MPG went from 31.8 to 34.6.
