97 Chevy Tahoe code Po 758

This is from Repair Pal...just Google your code (P0758) to find other helpful suggestions

OBD-II Code P0758 is defined as a Shift Solenoid B Electrical The purpose of the automatic transmission is to match the engine's optimum power and torque characteristics to the driver's desired rate of acceleration and speed by auto-selecting different gear ratios or 'speeds' to power the wheels. Shift solenoid B enables the transmission to shift from 2nd gear to 3rd gear. It does this by re-directing the flow of the transmission fluid which changes the position of the shift valves in the valve body.
When the code P0758 is set in the Powertrain Computer, it means that the Powertrain Computer or PCM is not seeing the specified rpm change that occurs during a shift from 2nd gear to 3rd gear. It's also not seeing the correct increase in road speed from the vehicle speed sensor.

P0758 Symptoms
  • Check Engine Light will illuminate
  • Vehicle will not shift from 2nd gear to 3rd gear properly
  • Decrease in fuel economy
  • In unusual cases, there are no adverse conditions noticed by the driver
  • In some cases, there may be performance problems and possibly misfire-like symptoms
Common Problems That Trigger the P0758 Code
  • Defective Shift Solenoid
  • Defective Shift Solenoid wiring or connector
  • Defective Valve Body
  • Dirty transmission fluid that restricts the hydraulic passages

    2-3 shift solenoid circuit

    P0758 Chevrolet 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
    What does this mean? When is the code detected?
    When the Powertrain Control Module (PCM) detects a continuous open, short to ground or short to power in the 2-3 Shift Solenoid (SS) valve circuit, then DTC P0758 sets.
    Possible symptoms
    - Engine Light ON (or Service Engine Soon Warning Light)
    - Transmission will not shift gears
    P0758 Chevrolet Description
    The 2-3 Shift Solenoid (SS) valve controls the fluid flow acting on the 2-3 shift valves. The 2-3 SS valve is a normally-open exhaust valve that is used with the 1-2 SS valve in order to allow four different shifting combinations. The solenoid attaches to the control valve body within the transmission. The Powertrain Control Module (PCM) controls the solenoid by providing the ground path.

    Multiple DTC's Solenoid, Torque Converter related... I ran an ODB II read & these are the codes it returned: P0740 - Torque Converter Clutch Solenoid Circuit P0753 - Shift Solenoid A...

    For starters I would run a fault code check to find out what item was affected . Next if nothing was amiss I would run the fault code reader to reset the CPU and see what parts of the CPU program was now working.

    I have 1998 volkswagon jetta with the check engine code P0758

    P0758 Volkswagen - Shift Solenoid 'B' Electrical

    Possible causes
    - Low transmission fluid level
    - Dirty transmission fluid
    - Faulty shift solenoid 'B' valve
    - Shift solenoid 'B' valve harness or connectors
    - Shift solenoid 'B' valve circuit is open or shorted

    Worst possible scenario is that the Transmission Control Module has noticed the solenoid is either taking too much current (a short circuit) or too little current (an open circuit). The problem could be in a few different places: wiring between the TCM and the tranny, wiring internal to the tranny, the TCM has gone bad, or the solenoid itself. You can narrow this down by checking the resistance of the solenoid coils at the TCM connector, then at the tranny connector on the tranny.
    Good luck, the mark 3 transmission is notoriously finicky.

    I had code p0758 solenoid circuit B electrical

    Here is the definition of the code. You may need to have a transmission shop take a look at it.

    P0758 HONDA Description Shift solenoid valve B is turned ON or OFF by the Transmission Control Module (TCM) in response to signals sent from the park/neutral position (PNP) switch, vehicle speed and Engine Control Module (ECM) (throttle opening). Gears will then be shifted to the optimum position.

    --------------- For car after 1995 it requires OBD2 tool and for car before 1995 it requires OBD1 tool.------- --------- You car will require OBD1 tool.There are very few auto parts store and repair centers who have OBD1 tool.In your case you required OBD1 tool.------ You can just contact local auto-parts store and they will guide you to the nearest store who has OBD1 tool.There you can get your car scanned.If there is error set in your cars computer, then you will receive the error code.As per error code it will point towards the faulty part causing this problem in your car.------------- -------------- The codes which you get is scanning will be mostly any of this following codes:--- DTC P0500 - Vehicle Speed Sensor Malfunction
    . DTC P0750 - Shift Solenoid "A" Malfunction
    . DTC P0753 - Shift Solenoid "A" Electrical Malfunction
    . DTC P0755 - Shift Solenoid "B" Malfunction
    . DTC P0758 - Shift Solenoid "B" Electrical Malfunction
    . DTC P0770 - Shift Solenoid "E" (SL) Malfunction
    . DTC P0773 - Shift Solenoid "E" (SL) Electrical Malfunction
    . DTC P1520 - Stop Light Switch Signal Malfunction
