My wife and I just ordered a 2007 EX EL. I have questions. I noted that the 6 speed auto does not have dip stick. The service dept did not offer much on how to change and refil the trans. How is that done? Is there just a service hole where you pump the fulid in like a rear end? I did buy the tow package so the unit will be rated to tow in the 9,000 lb range. The tow package was a 350 dollar option that I really wanted so I can tow my boat or 72 scout on a tandam axle trailer. In any event does the tow package have a different gear ratio-3:73? We drove one with an air leveling system that I guess is intended to level the load when towing. I did not buy the option. I figured a weight dist hitch would be cheaper. In any event will there be any ride characteristic changes between the air system and the standard issue suspension? Thanks.
