P073C
Stuck in Gear 7
Automatic transmission
Generic OBD-II
High
What it means
P073C means the transmission is stuck in 7th gear and can't shift out. It usually comes from a stuck shift solenoid or valve body, low or contaminated fluid, or an internal clutch/band that won't release. Because the vehicle is locked in a high gear, it launches poorly and often drops into limp mode.
High
Can I keep driving? Drive as little as possible — the transmission is stuck in 7th gear, so it launches poorly and may be in limp mode; have it diagnosed promptly.

How to diagnose & fix
Work through it in order
- Check the transmission fluid level and condition first.
- Scan and read freeze-frame data; note whether it's in limp mode.
- Test the shift solenoids and inspect the valve body for a stuck valve.
- Check line pressure and the solenoid wiring/connectors.
- If a clutch or band isn't releasing, internal transmission repair is needed. Clear and re-test.
FAQ
Quick answers
Is it safe to drive with P073C?+
Only minimally. Stuck in 7th the vehicle can barely accelerate from a stop, and forcing it risks further transmission damage. Get it inspected.
Can I just clear P073C?+
It returns as soon as the transmission fails to shift out of gear again. Clearing won't free a stuck solenoid, valve, or clutch.
