P076F
Gear 7 Incorrect Ratio
Transmission / gear ratio
Generic OBD-II
Medium
What it means
P076F means the transmission control module measured a gear ratio in 7th gear that doesn't match what it commanded — the input and output shaft speeds don't line up for that gear. It usually points to slipping clutches or bands, low or worn fluid, or a hydraulic/solenoid fault, rather than a wiring problem.
Medium
Can I keep driving? Usually drivable but you may lose 7th gear or feel slipping, and the transmission may enter limp mode — get it diagnosed soon, as slipping causes wear.
Common symptoms
What you'll notice
- Slipping or flaring when shifting into or holding 7th gear
- Harsh or delayed high-gear shifts
- Higher-than-normal engine RPM at highway speed
- Limp mode (stuck in a lower gear)
- Check-engine light on
Common causes
Most likely first
- Low transmission fluid level reducing clutch/band apply pressureLikely
- Dirty or worn-out transmission fluidCommon
- Worn clutches, bands, or friction elements for 7th gearCommon
- Stuck or failing shift solenoid affecting the 7th-gear circuitLess often
- Valve body or hydraulic control faultLess often
How to diagnose & fix
Work through it in order
- Scan for codes and read freeze-frame data to confirm the fault and note which gear it sets in.
- Check transmission fluid level and condition first — low or degraded fluid is the most common cause of a ratio error.
- Service the fluid and filter, and inspect the pan for clutch material or metal debris.
- Test the shift solenoids and inspect the valve body for sticking or wear.
- If pressures and solenoids are good, internal wear (clutches/bands) is likely and the transmission needs teardown. Clear and re-test.
FAQ
Quick answers
Is it safe to drive with P076F?+
Short trips are usually fine, but a gear that's slipping generates heat and accelerates wear, so avoid extended or high-load driving until it's checked.
Can I just clear P076F?+
It will clear, but returns once the transmission commands 7th gear again unless the fluid, solenoid, or internal wear behind it is fixed.
