P0773
Shift Solenoid E Electrical
Transmission
Generic OBD-II
Medium
What it means
P0773 means the transmission control module detected an electrical fault — an open or short — in the shift solenoid E circuit. This solenoid meters hydraulic pressure to engage gears, so the fault shows up as harsh or erratic shifting, slipping, or limp mode. The engine still starts and runs; the issue is electrical, usually a bad solenoid, wiring, or connector.

Can I keep driving? Usually driveable, but the transmission may shift harshly, slip, or enter limp mode — get it diagnosed soon to avoid overheating and further wear.
Common symptoms
What you'll notice
- Check-engine light on
- Harsh or delayed shifting
- Transmission slipping or stuck in one gear
- Limp mode (reduced gear range)
- Reduced fuel economy
Common causes
Most likely first
- Faulty shift solenoid E (open or shorted winding)Likely
- Open or shorted wiring in the solenoid E circuitCommon
- Loose or corroded electrical connectorCommon
- Low or dirty transmission fluidLess often
- Faulty transmission control module (TCM)Less often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and scan for related shift-solenoid codes.
- Inspect the solenoid E wiring and connector for damage, chafing, or corrosion.
- Measure the shift solenoid E resistance and compare to spec — an out-of-range or open reading points to the solenoid.
- Check transmission fluid level and condition; service if dirty.
- If the circuit and solenoid test good, verify TCM operation.
FAQ
Quick answers
Is it safe to drive with P0773?+
Short term, yes, but the transmission may shift harshly or fall into limp mode. Driving a slipping or overheating transmission risks internal damage, so repair it promptly.
Can I just clear P0773?+
It will return until the solenoid or its wiring is fixed. Because this is an electrical code, start with the connector and a resistance test of the solenoid.
