I have an auto 08 .. for towing i understand its 4th gear and D for everyday driving, but what about 3 2 1L? if i were to help someone stranded that needs help getting pulled out would i use 4L? just trying to understand the usage of the lower gears and what gear should i be using when trying to pull someone out of a ditch or something along those lines ... sorry if this is the incorrect section to be posting
