Does anyone know what this suggests??

P0717 (Porsche codes 91 and 92) Stall speed, transmission input - signal implausible Gear monitoring, transmission input speed - signal implausible Possible causes: - Open circuit - Wiring - (Porsche Short circuit to B+ - Transmission input speed sensor code 91) - Short circuit to ground - Torque converter - ATF level not OK - Transmission - Slipping clutch or brakes - Faulty torque converter.
P1770 Load signal from ECM Substitute Motronic value, fixed shift map (KFO)
Both codes can be caused by not having all the wiring connections tight.
