Tranny question
 

Well guys im new to the 12v. I just got a 94 dodge 4x4 auto. I have noctied that sometime it shift in and out of gear when driving on the highway. Also if change the filter should I adjust the bands. If so how do I do that. All the help would be great. It only has 82,000 miles on it and its all stock. Also how do I find out which tranny i have. Thanks for all the help.
