I've got a 1994 Dodge 1500 4x4 auto with 83,000 miles on it that I bought from a guy anout 6 months ago and it had a new transmission put in it at 30,000 miles. The guy that I bought it from said the fluid had newver been changed. I'm only going to be pulling a small trailer with a mower with it but should I get the transmission flushed since the fluid is pretty old? I gave $6500 for the truck and a flush is $110 so do you think it would be worth it? I know my dad bought a car a few years ago and had the tranny flushed and it wasn't long after that that it went out so I don't know if this is a good idea or not.
