CodePage.genericDisclaimer
¿Qué significa esto?
Code P0771 relates to the transmission shift solenoid or pressure control system variants.
Diagnostic system: Transmission control and shift monitoring
On a Dodge Challenger, the P0771 code should be diagnosed as part of the transmission control and shift monitoring group. Related codes and live data from this same system can change the repair priority, so avoid replacing parts from the code name alone.
Most Common Causes for Dodge Challenger
- Solenoide de cambio de transmisión defectuoso
- Solenoide de control de presión de transmisión defectuoso
- Líquido de transmisión bajo, sucio o quemado
- Cuerpo de válvulas de la transmisión desgastado
- Arnés de cableado dañado o roto
Síntomas a tener en cuenta
- La luz de Check Engine está encendida
- Cambio de marcha brusco o duro
- La transmisión se queda atascada en una marcha
- La transmisión patina entre marchas
- Enganche de marcha retrasado
CodePage.beforeReplacing
- Check fluid level and condition when the vehicle design allows it.
- Scan transmission module data, not only generic engine codes.
- Look for speed sensor, solenoid, and electrical codes before assuming internal transmission failure.
- Check for blown fuses, weak battery voltage, and damaged connectors before buying major parts.
Cómo Diagnosticar
CodePage.commonMistakes
Assuming the transmission needs rebuilding before checking fluid, sensors, solenoids, wiring, and control-module codes. Always confirm the fault with freeze-frame data, live data, visual inspection, and circuit checks before spending money on parts.

Can I drive with the P0771 code?
If the check engine light is solid, you can usually drive to a safe location or mechanic. If the light is flashing, pull over immediately to prevent catastrophic engine or catalytic converter damage.
Will the P0771 code clear itself?
Once the underlying problem is fixed, the engine computer will run its self-checks. If it passes over several drive cycles, the light will turn off automatically. You can also clear it immediately using an OBD2 scanner.
Will this code fail an emissions test?
Yes. If the Check Engine Light is on due to the P0771 code, your Dodge will automatically fail an OBD2 plug-in emissions or smog test.
What should I check first for P0771?
Check fluid level and condition when the vehicle design allows it. Scan transmission module data, not only generic engine codes. Look for speed sensor, solenoid, and electrical codes before assuming internal transmission failure.
