Ok I'll keep this simple. I have an 02 GTP "Turbo" with a custom trans. It was working fine for a while and then my "TCS Off" light just went on by itself followed by the Check engine light which the code was DTC P0715 Input/Turbine Speed Sensor Circuit Malfunction.
I had a local shop replace the sensor and the whole wiring harness in the trans. Heading back from the dyno the check engine came on again and this time I lost 4th gear.
If I erase the code I have 4th gear again but it comes back after a couple miles of driving.
I have been in contact with Trannyman but I wanted to post this incase someone else has had this issue.
