Have u had any transmission problems

Yes -and be careful. 1/stay away from anyone who recommends doing a tranny flush. 2/start with the basics like checking the fluid for level,colour,smell 3/ if level is low be advised that transmissions do not use up fluid (if it's low an ounce or two and colour is good you can top it up- but if it's down a quart then you have a leak). 4/ be prepared to do a lot of research on your own because you are entering the "Twilight Zone" and 99 out of 100 mechanics and or so called tranny specialists are primed to feed you VooDoo lore,myth, half truths and down right lies!!
