Hi guys, I am the proud new owner of a 1976 Dodge Mobile Traveler. It has a mopar 318 engine. As I have been driving it, the automatic transmission seems to have 3 gears, the one it starts out in when stopped, a 2nd gear starting at about 15 mph, and a 3rd one starting at about 30 mph. When I get up to higher speeds, it seems like there should be one more gear (like an overdrive gear), but it does shift into one. Either it doesn't have one, or it isn't shifting into it. Any thoughts?
