No OD, P0715,p0717

[GAS]

So I am heading home after work, doing 75 ish. All of a sudden the trans donshifts to 3rd, hear a loud rattle. No leaks, clean pink fluid, no OD light flashing.

Hoping for the cheap fast fix i replace the shift lever/OD switch. On test drive
it shifts in and out of OD, hunting up and down, OD light starts flashing.
Get home pull codes and get P0715, P0717

Replace the turbine shaft speed sensor, acts the same.

No slippage, just no OD, no free coasting,

Ideas??

Thanks

Both P0715 and P0717 are transmission fault codes. Which is why your od light was flashing.

Both are input turbine speed sensor trouble codes.
