I will be changing the gear ratio on my 2000 Eddie Bauer 4x4, 5.4 liter from the factory 3.55's to 4.10's and I have been searching the forums and can't find the answer to this question; Will the speedometer require recalibration? I am not changing the tire size. I cannot find a consistent answer as to which sensor controls the speedometer, the rear differential sensor or transmission sensor. Thanks for any help on this.
