F-250 & F-350 gear ratio question ?

4r100 P0715/P0717 trouble codes.
P0715 indicates that there is an electrical fault in the TSS circuit. It CANNOT be anything inside the trans. Either the sensor is bad, the wiring harness has a fault, or the PCM has failed.

P1728 - Transmission Slip Fault

****SOLD*******
****** SOLD ****** 2000 Excursion XLT 4x4 V10, or should I say V9. A spark plug was ejected and there is not enough material in the head for an insert. I won't put the money into it to replace the heads or the engine, so it has to go. It has 247,800 miles. Up until this incident it ran and...- Mark Kovalsky
