Hi All,

I have a 2007 Frontier Crew Cab 4x4 LB, just turned 106k miles. I wanted to check and see if there are any issues changing the coolant and the transmission fluid and filter.  I have had no issues with either, since buying the truck new.  I have not replaced the radiator but bypassed the tranny cooler in the radiator a number of years ago.  I have the tow package on the vehicle and have towed a 5k boat but only for 1-2 mile distance to a boat ramp.  That was a few years back.  truck has been a secondary vehicle for a few years but I want to start using it more and want to go through all the fluids, but I know things can get ugly between the coolant and the transmission fluid.
