Have Code P0760 Shift Solenoid C Malfunction . I checked solenoid resistance their 1.5 ohms.Check wiring integrity it’s good. Can anyone point me in the right direction.it’s the 62te transmission

Scope the control side of all the solenoids. Make sure each solenoid has a good/equal voltage spike upon turn-off.

Copy and Past from SI

Theory of Operation

Six solenoids are used to control the friction elements (clutches). The continuity of the solenoid circuits is periodically tested. Each solenoid is turned on or off depending on its current state. An inductive spike should be detected by the PCM during this test. If no spike is detected, the circuit is tested again to verify the failure. In addition to the periodic testing, the solenoid circuits are tested if a gear ratio or pressure switch error occurs. In this case, one failure will result in the appropriate DTC being set. The MIL will illuminate and the transmission goes into neutral, if the DTC is set above 35 km/h (22 mph), Limp-in mode when vehicle speed is below 35 km/h (22 mph).

- When Monitored:
Initially at ignition on, then every 10 seconds thereafter. The solenoids will also be tested immediately after a gear ratio error or pressure switch error is detected.

- Set Condition:
Three consecutive solenoid continuity test failures, or one failure if test is run in response to a gear ratio or pressure switch error.

Thank you for your help .I checked for spikes on the solenoid control side was seeing around 43.9v on all of them.
