P0717 is a diagnostic trouble code (DTC) for "Input/Turbine Speed Sensor No Signal". This can happen for multiple reasons and a mechanic needs to diagnose ...

4 engines non told, (it tells tranny that is there)
I assume shift links not bad PRNDL, but if P works and D so must R
a/t box 4T45e I guess. or 6T40 or 6t is six speeds.
check fuses.
scan the PCm for P0700 errors for tranny
check line pressure per service manual I have it. can tell it but takes 400 psi gauge, but here is spec for Reverse.
vac port at 0hg vac, 255 psi min.
vac port to 19inches HG, port main 74min.
these modern trannys have pressure regulator. that can be bad but gee the scans tell you that if true, not scanning is why you miss all that and tons more. From ATSG manual, 4T45e
here is DTC list, and more ,scan first, or go broke guessing.

What engine does it have ? 3.6 or 3.8 l
Circuit Description
The automatic transmission input speed sensor (ISS) is a permanent magnet with a coil of wire wound around it. The ISS mounts in the case cover facing the reluctor wheel of the input shaft. As the reluctor wheel is driven by the turbine shaft, an AC signal is induced in the input speed sensor. Higher vehicle speeds induce a higher frequency and voltage at the sensor.
There is a fixed air gap between the sensor and the teeth on the sensor reluctor wheel. The ISS input is used by the powertrain control module (PCM) in order to control line pressure, TCC apply and release and transmission shift patterns. This sensor is also used to calculate the gear ratios and TCC slippage.
If the PCM detects a low input speed while the vehicle and engine speeds are high, then DTC P0717 sets. DTC P0717 is a type B DTC.
Your best bet , take your vehicle to a qualified repair shop that know's how to test correctly

Probably plugged passage's , not the EGR valve .
What type code reader are you using to read these codes ? I have factory service info. Doesn't show P0842 or P0642 , no such codes . You don't show what engine yours has , I'am assuming you have 3.5 L !

Circuit/System Description
The input speed sensor (ISS) is a hall-effect type sensor. The sensor faces the 1-2-3-4 and 3-5-R clutch housing machined teeth surface. The sensor receives 8.3-9.3 volts on the input/output speed sensor (ISS/OSS) supply voltage circuit from the transmission control module (TCM). As the 1-2-3-4 and 3-5-R clutch housing rotates, the sensor produces a signal frequency based on the machined surface of the 1-2-3-4 and 3-5-R clutch housing. This signal is transmitted through the ISS signal circuit to the control solenoid (w/body and TCM) valve assembly. The control solenoid (w/body and TCM) valve assembly uses the ISS signal to determine line pressure, transmission shift patterns, torque converter clutch (TCC) slip speed and gear ratio.
Circuit/System Verification
Engine idling, observe the scan tool Transmission ISS parameter while varying the engine speed. The Transmission ISS parameter should change with the engine speed and not drop out.
Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.
Ignition OFF, remove the control valve body cover. Refer to Control Valve Body Cover Replacement.
Connect the TCM harness connector.
Disconnect the input speed sensor (ISS) from the control solenoid (w/body and TCM) valve assembly.
Connect the J 38522 between the supply voltage terminal B and ISS signal terminal A at the control solenoid (w/body and TCM) valve assembly. Refer to Control Solenoid Valve and Transmission Control Module Assembly Input Shaft Speed/Output Shaft Speed Input Test for further instructions.
Set the J 38522 signal to 8 volts, the frequency to 120 and the percent duty cycle to 50.
Ignition ON, observe the scan tool Transmission ISS parameter. The scan tool Transmission ISS parameter should be between 100-400 RPM.
? If not within the specified range, replace the control solenoid (w/body and TCM) valve assembly.
If all circuits test normal, test or replace the input speed sensor.
Control Valve Body Cover Replacement
Disconnect the negative battery cable. Refer to Battery Negative Cable Disconnection and Connection.
Remove the air cleaner assembly. Refer to Air Cleaner Assembly Replacement.
Remove the oil cooler inlet hose (1) from the retainer on the control valve body cover.
Remove the oil cooler outlet hose retainer nut (5) from the control valve body cover.
Remove the oil cooler outlet hose (4) from the retainer on the control valve body cover.
Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle.
Remove the left engine splash shield. Refer to Engine Splash Shield Replacement.
Drain the transmission. Refer to Transmission Fluid Replacement.

DTC P0717: Input Speed Sensor Circuit Low Voltage
The automatic transmission input speed sensor (ISS) is a permanent magnet with a coil of wire wound around. The ISS mounts in the case cover facing the reluctor wheel of the input shaft. As the reluctor wheel is driven by the turbine shaft, an AC signal is induced in the input speed sensor. Higher vehicle speeds induce a higher frequency and voltage at the sensor. There is a fixed air gap between the sensor and the teeth on the sensor reluctor wheel. The ISS input is used by the transmission control module (TCM) in order to control line pressure, torque converter clutch (TCC) apply and release, and transmission shift patterns. This sensor is also used to calculate the appropriate gear ratios and TCC slippage. This diagnostic indicates stuck, erratic, or intermittent conditions in the system.
Diagnostic Aids
• Road test the vehicle while monitoring the Transmission ISS parameter on the scan tool. The Transmission ISS parameter should vary with engine speed changes and not abruptly drop out.
• Inspect for an open or shorted AT ISS wire.
• Inspect for a disconnected AT ISS connector.
• Inspect for a faulty AT ISS.
P0717 is for the transmission input speed sensor , which inturn will bring up the other code P0700 for the Trans Control Module , so i would suggest having the codes cleared and see if they come back as sometimes a glitch can occour , if codes reappear and so do the symptoms i would replace the input speed sensor , it reads the primary pulley speed and sends info to the TCM and as far as i know there are no diagnostic s to carry out as this sensor either works properly or fails so get it changed and hope its not the TCM as well, keep me posted if you wish
