Ok, so now I think my tranny is too cool.
Not awesome cool, but not getting warm enough. I took it on a 4 hour trip (2 each way) and cruise control wouldn't work. The button light comes on, but when I try to set the speed nothing happens. As far as I could tell the torque converter is locking up. Driving at exactly 60 mph my tach reads exactly 2000 rpm. The speed limit was 55 most of the time, so I would think that cruise control would work normally after driving a few minutes at that speed.
Anyone have any ideas?
P.S. at the end of the trip I felt the cooler and hoses and they didn't feel much warmer than the outside air...
