One day the reverse in my 2001 Dodge Dakota just stoped working. The rest of the gears seem to be doing ok, I have to drive it but only park where i can "pull thru". With out costing me an arm & leg, or not even know what it might be, any ideas out there. Not sure even where to start.I have heard there are bands in the transmission, and have several people offering to fix or replace. I dont know what all I should have checked.
