What P2730 means
P2730 is stored when the control line of solenoid E sits too high, pointing to contact with a supply voltage. GM's Allison 1000 logic looks for a power short at the PCS 1 output and treats it as Type A. Its 2016 six-speed tables word the code as circuit high for an open or a power short, so there a broken wire may show up as P2730 instead of P2727. The 2023 Corvette dual-clutch TCM switches the driver on and compares the sense voltage with a limit that depends on supply, about 0.7 V at low and 1.1 V at high battery voltage (Type A); Ford's TR9070 calls the same fault shorted load. No public bulletin links P2730 to a particular repair, so standard tracing of harness, connector and solenoid applies.
P2730 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyMedium
- Typical labor0.5 to 5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2730
- MIL on and transmission in fail-safe
- Harsh or missing shifts
- Code sets again immediately after clearing
Common causes of P2730
- Most likelyControl wire chafed against a supply circuit
- PossibleOpen line on units that report it as high (GM six-speed)
- PossibleDefective solenoid E
- Less likelyTCM driver fault
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2730 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. |
| 30 | The exact fault in that area. |
What to do next
- Note P2730 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 P2730
What does P2730 mean?
P2730 means "Pressure Control Solenoid E Control Circuit High". P2730 is stored when the control line of solenoid E sits too high, pointing to contact with a supply voltage. It is a generic code, so it means the same on every make.
Is it safe to drive with P2730?
Drive gently and only to a workshop. With P2730 the car can go into limp mode (reduced power) to protect itself.
Will P2730 fail an emissions test?
Yes, it can. P2730 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 P2730 to fix?
Difficulty: medium. A typical repair takes 0.5 to 5 hours of work. This is a job for a workshop.
Will P2730 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
