Probably a dumb question. I just had an EZ box put on my 02 quad cab. Before the EZ, I would always keep OD off when driving 55 or 60. (not enough power) But with the EZ, I have plenty of power at those speed with only about 1500 rpm. Did I mention that I have an automatic ? Well, at that low rpm, am I in danger of harming the transmission (flat or hill) if I am unloaded ? Also, if I am pulling my 19ft camper trailer (less than 4000lbs), am I in danger of transmission damage (that speed or even 70 or more ?)
