Trans Range Sensor OBD Codes PO705 and PO708
The local AutoZone read the OBD codes on my 97 4X4 5.4 as DTC PO705, Trans Range Sensor Circuit Malfunction, (PRDNL Input), and PO708, Trans Range Sensor Circuit High Output.
About 10% of the time this tranny shifts extremely hard into 1 and 2, less hard into 3, sorta seems like it's in Lo range. A fluid change made the problem disappear for a few days.
Where do I start to solve this problem ? Is a part needed that is accessible without going inside the tranny, and can a guy of average ability do it without disaster ?
Thanks for any suggestions. This rascal has 155k on the clock by the way. Fluid was changed 3 times in it's life.
