DTC P0757 L61
Circuit Description
The 1-2 shift solenoid valve (1-2 SS Valve) is a normally open exhaust
valve that in conjunction with the 2-3 shift solenoid valve (2-3 SS Valve),
allows four different shifting combinations. The 2-3 SS Valve is attached to
the control valve body, within the transaxle. The PCM monitors the actual gear ratio
and compares the actual gear ratio with the commanded gear ratio. The diagnostic will
detect the following conditions: A stuck off 2-3 SS Valve, or a stuck off 2-3
Shift Valve. These conditions will cause the actual gear ratio to be different from
the commanded; 2nd gear ratio in 3rd and 1st gear ratio in 4th and thus set DTC P0757.

valve that in conjunction with the 2-3 shift solenoid valve (2-3 SS Valve),
allows four different shifting combinations. The 2-3 SS Valve is attached tot
he control valve body, within the transaxle. The TCM monitors the actual gear ratio
and compares the actual gear ratio with the commanded gear ratio. This diagnostic
will detect the following conditions: A stuck off 2-3 SS Valve, or a stuck off

from the commanded; 2nd gear ratio in 3rd and 1st gear ratio in 4th and thus set DTC
P0757.
