Ok I seem to be getting mixed messages from all these posts about changing tranny fluid. I have an 02 fire 2200 with 71,300 miles. I don't know if the fluid has ever been changed in it. 3 months ago I put on an interceptor. Just need to know if I should change it or not. some people say they have problems when they change it and some don't. so i don't know what to do. would really appreciate the help. thanks in advance.
