trans trouble on 2000 Dodge Ram Van 1500

I seem to have lost 1st gear. Am I looking at a total rebuild/replace or a minor(ha!) problem?

sometimes your better getting a use transmission with low miles, google LKQ they offer good prices and it comes with a warranty

This is a common problem with these trans'. check the fluid and see if it smells burnt, or looks dark. Chances are you will need a trans, or an overhaul...
