What P27CC means
With P27CC the transmission controller has seen solenoid R lose its circuit or its effect for short moments only. A public, code-specific manufacturer description does not exist. The two known users of solenoid R, GM's Corvette dual-clutch transmission (23OBDG07, valve 4) and Ford's TR9070 (SPV4), document only lasting electrical faults and stuck conditions for it. CARB 13 CCR 1968.2 requires output monitoring for automatic transmission solenoids. Since the fault may have healed by the time the car reaches the workshop, freeze frame records, the number of occurrences and a careful look for oil wicking into connectors or a loose pin are more telling than one resistance reading.
P27CC at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyMedium
- Typical labor1 to 4 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P27CC
- Intermittent MIL
- Sporadic rough or delayed shift
Common causes of P27CC
- Most likelyLoose or spread terminal pin
- PossibleTransmission fluid wicking into the connector
- Less likelyHarness conductor breaking under vibration
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P27CC means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 7 | Area: transmission. |
| CC | The exact fault in that area. |
What to do next
- Note P27CC and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P27CC
What does P27CC mean?
P27CC means "Pressure Control Solenoid R Intermittent". With P27CC the transmission controller has seen solenoid R lose its circuit or its effect for short moments only. It is a generic code, so it means the same on every make.
Is it safe to drive with P27CC?
Drive gently and only to a workshop. With P27CC the car can go into limp mode (reduced power) to protect itself.
Will P27CC fail an emissions test?
Yes, it can. P27CC is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P27CC to fix?
Difficulty: medium. A typical repair takes 1 to 4 hours of work. This is a job for a workshop.
Will P27CC clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
