SOURCE: Road speed sensor
So the diagnostic code says the speed sensor is bad in the transmission? Make sure all the wires are tight to the transmission and in good shape. If they are you probably need to replace the sensor. If the transmission controller doesn't get the correct speed values it would cause some problems shifting. Wiring to a transmission can cause faults since the wires are subjected to heat and vibration. If you can't find any problems with the wiring or the wiring connectors it just might be the sensor is bad (stuff fails).
I do have to say that I am not sure what G-68 means. The diagnostic codes are usually five digit numbers with maybe a letter.

what you probably have is a problem with the transmission control module. somehow the solenoids inside the transmission are not operating like they should because the module is not sending the the signal from the ecm. this is a good starting point. you could also try adding lucas to the trans because you could have a stuck solenoid. hope these are helpful options please rate...thanks

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.
The 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).
