Ford requires the transmission fluid be changed every 150,000 miles. How often is the fluid to be changed in the Aisin?
Sorry for the Hi-Jack couldn't find the thread where we were discussing this !!!
We had been talking RPM's and actual speed in 6th at 70. I know you said I should be different but here is "my proof". All pics taken one right after the other.
Tried to get pics at perfect angle but the needles are right on the mark.
I don't remember exactly what I said on the other thread but it seems to me that I might have told you that if your tac and speedo are right your tires are low on air or bald and need replacing. With 235/80 r 17 tires and 4.10 gears your engine will be running very close to 1910 rpm at 70 mph. It looks like your speedo and gps agree ... I'm sure your tires aren't worn out, so my guess is that your tac is off.
