So I need to ask is there a speed sensor in the 5R55s transmission in addition to the VSS sensor in the rear end (or that the VSS is take off the ABS sensors…)
And if there is a speed sensor in the transmission??
If so does anyone know if it has a different pulse rate that the VSS single?? Or better the two pulse rates for the two.
Had a talk with gear venders, they claim A) no room for one…B) nothing can improve my MPG, C) My 5R55s has its OWN VSS/speed sensor and if I switch in a second overdrive the PCM will flip out as the VSS does not compute with the Speed sensor in the transmission.
They claim FORD compiling with CAFA gives the Explorer all the POSSIBLE MPG and nothing can change that….that it is a brick.
I strongly disagree with his words.
BUT just as I will need a Brown Wire switch so the 4WD Drive will not engage when running double overdrive I may need to find a way to override the Transmission speed sensor as well.
Thanks.
