CODES

Its the transmission turbine input shaft. Not the turbo.
Insufficient input from TSS Sensor. PCM detected a loss of TSS signal during operation.

What does that mean?

Transmission slipping?

CODES

Or could be that the difference in the turbine shaft sensor compared to the output shaft sensor is not what the PCM expected?

CODES

Tranny slip is a possibility. But don't expect the worst right off the bat. Do the things that cost nothing like check the fluid level, temp. and condition of the fluid.
