Check engine light and the trac off light came on the other day at some point. There was a snow storm. Roads became bumpy and driving over snow drifts. I believe the car is in limp mode. At around thirty mph it had higher rpm's around four. Hooked a scan tool up gave me p0753, p0758, p1860, p0135. What would cause all these codes to happen at once?

Good morning.

The codes are for shift solenoid voltages and voltage for the O2 sensor.

It is possible the connector at the transmission may have been damaged from the snow or dislodged. check the connector and see if there are any burned or damaged pins.

P0753 trouble code in the PCM is a faulty shift solenoid. Some other causes include blockage in the hydraulic system inside of the transmission, a mechanical failure in the transmission, a low transmission fluid level, and dirty or contaminated transmission fluid.

P0758 CHEVROLET - 2-3 Shift Solenoid Circuit Electrical Possible causes Low transmission fluid level Dirty transmission fluid Faulty 2-3 Shift Solenoid Valve 2-3 Shift Solenoid Valve harness or connectors 2-3 Shift Solenoid Valve circuit is open or shorted.

P1860 CHEVROLET - TCC PWM Solenoid Circuit Electrical 6 Comments | Add Comment Possible causes Faulty Torque Converter Clutch Pulse Width Modulation (TCC PWM) Solenoid Torque Converter Clutch Pulse Width Modulation (TCC PWM) Solenoid harness is open or shorted Torque Converter Clutch Pulse Width Modulation (TCC PWM) Solenoid circuit poor electrical connection.

P0135 CHEVROLET - HO2S Heater Performance Bank 1 Sensor 1 Possible causes Faulty Heated Oxygen Sensor (H2OS) Bank 1 Sensor 1 Heated Oxygen Sensor (H2OS) Bank 1 Sensor 1 circuit fuse Heated Oxygen Sensor (H2OS) Bank 1 Sensor 1 circuit open shorted to ground Heated Oxygen Sensor (H2OS) Bank 1 Sensor 1 circuit poor electrical connection Faulty Power train Control Module (PCM).

Check for any damage to the loom going to the transmission, also try clearing the codes and see what resets, some of these may be history codes that are not relevant. start here.
