2000 Dodge Durango shifting out of second

1. What transmission do I have?
2. The trans would slip in and out of gear.
3. Sometimes not shift into 3rd or silip out of second on a hill and also any other gear.
3. I have adjusted the front and rear bands and the tv cable. It now will not shift at all out of second gear
72 inch pounds on front and rear 3/16 inch play in cable wich is stock position.
