Zd30 auto trans fault
I’m having a problem with the trans. It gets stuck in 2nd gear. If I stop and turn the car off it fixes it for about 10 mins. The scan tool says a/t speed sensor 1 fault. In the data mode speed sensor 2 is reading the vehicle speed but speed sensor one stays on 0kmh. The speedo is working. Is there 2 sensors. I only see the one on the rear of the transfer case.
Any ideas would be appreciated.

They only have one speedo sensor. Maybe ring Wholesale Automatics and ask them.
