Circuit Description
WARNING: This page is about a different car, the 2007 Saturn Sky. However, it is still accessible from the selected car via links, so may be relevant.
The 4-5 shift solenoid (SS) valve is a normally-closed exhaust valve. When the 1-2 and the 2-3 SS valves are both OFF, the 4-5 SS valve turns off to shift the transmission into 5th gear. When either of the other two shift solenoids are ON, the 4-5 SS allows powertrain braking. The 4-5 SS valve is attached to the control valve body, within the transmission.
The transmission control module (TCM) monitors the actual gear ratio, and compares the actual gear ratio with the commanded gear ratio. DTC P0761 sets under two conditions:
- A stuck OFF 4-5 SS valve
- A stuck OFF 4-5 shift valve
If the TCM detects a 1-2-3-5-5 shift pattern, then DTC P0761 sets. DTC P0761 is a type B DTC.
