Question about 2003 Volkswagen Jetta TDI
Shifting hard between 1st and 2nd gear Dealer reading is G-68 diagnostic
indicating speed sensor in tranny, or turque converter.
78,000 miles This is a Jetta Turbo 1.8 Your thoughts will be appreciated
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.
