I have a 2007 fx4 off road ranger,v6 auto with tow package(bougth it new) use it on week ends, have 50,000 miles. very reliable, got
me to where we go,especially in snow,would like better gas mileage about 17-20 mpg highway.
I have two issuses , since new the transmission when driving and the speed drops to 20 miles a hour and it down shifts it feels if someone kicked me in the seat,trips to the dealer resulted in reprogram computer,work on the vavle body chech transmission.The
dealer said that is the way this transmission works.
Second issuse is rust, looking underneath there is rust all over when I brought it to the dealer they said they can't do anything unless it rust THRU.
I own an older Ranger. My transmission shifts the same way. It's annoying but that's the way the transmission operates, so your's has no problems. As for the rust I don't think I can help you. Do you live somewhere where it snows a lot?
