This is the range for the most common fix, transmission speed / range sensor replacement. Which repair your car needs depends on a proper diagnosis.
The input speed sensor measures how fast the shaft entering the transmission is turning. The computer uses it, along with the output speed, to judge shifting and torque converter slip. It now gets no signal from this sensor, so shifts can be harsh, late or stuck in one gear.

- Most common cause
- Failed input speed sensor
Shifting may be harsh and the car may go into limp mode. Drive gently.

Check this first
Check the transmission fluid level and condition if there is a dipstick, and look at the sensor connector on the side of the transmission for fluid or corrosion. Dirty fluid can foul the sensor tip.

P0717 questions
Is the sensor easy to reach?
Often yes, because many sit on the side of the transmission case with one bolt and a plug. On some cars it is inside the case and requires the pan or the valve body to come off.
Can fluid cause it?
Yes. Fine metal in worn fluid can coat the sensor tip and weaken its signal. A fluid check is worth asking for, because metal in the fluid also hints at wear that a sensor will not fix.
Is it costly?
Typically a lower-cost transmission repair if the sensor is outside. The price rises if it is inside the case, so ask the shop where it is on your car before you approve the work.
