code p 0700 refers to transmission control system/MIL---malfunction==== causes --TCM---wiring
check all connections and wiring condition or replace the TCM
code p 0717 refers to turbine shaft speed (TSS) sensor ---no signal====causes ---wiring---TSS sensor---ECM/TCM
logically the TSS reports to the TCM to facilitate ratio changes so if the wiring , connections etc are not good then one will affect the other
Take it to an accredited auto transmission specialist shop, have it properly diagnosed and a quote
do not confuse a TSS with a VSS sensor as they are two different speed sensors in the same box

Input speed sensor is located inside the transmission. The sensor is located next to the sprocket for the input shaft. The sensor is held in place with 2 6mm bolts, one for the sensor, one for the wiring harness.

Vehicle Speed Sensor Removal Installation

it is the turbine speed sensor(TSS) and senses the torque converter out put shaft speed
It will be shown in the workshop manual or any accredited transmission specialist shop will show you where it is

input speed sensor for transmission is faulty which will throw the 717 code and when it does it will also tell "root" TCM (transaxle control module) to include the 700 code.
700 happens when it detects an issue with the TCM.
717 happens when the sensor is bad.
- Faulty Transmission Speed Sensor
- Transmission Speed Sensor harness is open or shorted
- Transmission Speed Sensor circuit poor electrical connection

It is the gearbox speed sensor fault.

P0717 - Input/Turbine Speed Sensor Circuit No Signal.

P0717 code means that the computer isn't getting any signal from the sensor. Either the sensor is dead or there's a circuit issue (bad wiring, etc).

The computer wants to know if the transmission is working properly. So it reads the speed of the input shaft and compares it to the speed of the output shaft. It knows which gear you're in because it commanded the transmission to shift into that gear. So, with the input speed, the gear selection, and the output speed, the computer can calculate how efficiently the transmission is working. If the speed is off, it knows that something is slipping inside the transmission. It can then try to boost the fluid pressure to compensate. If that doesn't work, it sets a different trouble code.

Hope helps (remember to rate and comment this answer).

P0717: Input/Turbine Speed Sensor Circuit No Signal.
This code shows because the computer isn't getting any signal from the sensor. Either the sensor is dead or there's a circuit issue (bad wiring, etc).

The Input/Turbine Speed Sensor is the sensor the computer uses to to monitor the the efficiency of the transmission. The computer reads the speed from the input shaft and compares it to the speed of the output shaft. If the speed is off it attempts to correct it by boosting the fluid pressure to compensate. When that fails it trips the P0717 error code. In most cases either the sensor is dead or there's a problem in the wiring harness.

There are issue of intermittent connection trouble with this circuit. That would cause the on off problem.
Hope this helps.
