where is the TCM located on my trani or the motor or elsewhere? on 1995 Chrysler LeBaron

Iv'e been driving my car stuck in second gear for about 30 days then all of a sudden it now won't go forward at all, the only gear that works now is reverse. What can I do to repair this. what parts do I need to replace and where are loccated under the hood. where can I get a diagram of my engine with part descriptions?
