What P076F means
P076F means the ratio in seventh gear is wrong: input speed divided by output speed does not match the commanded gear, so a clutch slips or another gear is engaged. It only exists on transmissions with seven or more gears. Ford's 10-speed 10R80 and 10R140 list it in bulletins together with the other ratio codes and the check engine light – causes include a migrating sleeve on a clutch cylinder causing hydraulic leaks and sticking valve body valves. Ford's ratio check elsewhere flags more than 30 rpm off for 1.8 s three times. On GM's Corvette with seven-speed manual gearbox, P076F is a plausibility check of the gear position sensor instead (ratio window 0.41–0.50), after one trip.

Symptoms of P076F
- Slipping or flaring engine speed in seventh gear
- Harsh or delayed shifts
- Check engine light, transmission warning, possibly limp mode
Common causes of P076F
- Most likelyHydraulic leak at the seventh gear clutch (Ford 10R80: clutch cylinder sleeve)
- PossibleSticking valves in the valve body or solenoid
- PossibleFluid level or condition
- PossibleGear position sensor implausible or not learned (GM manual only)
- Less likelyTurbine or output speed sensor
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P076F means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 7 | Area: transmission. |
| 6F | The exact fault in that area. |
What to do next
- Note P076F 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 P076F
What does P076F mean?
P076F means "Gear 7 Incorrect Ratio". P076F means the ratio in seventh gear is wrong: input speed divided by output speed does not match the commanded gear, so a clutch slips or another gear is engaged. It is a generic code, so it means the same on every make.
Is it safe to drive with P076F?
Drive gently and only to a workshop. With P076F the car can go into limp mode (reduced power) to protect itself.
Will P076F fail an emissions test?
Yes, it can. P076F 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 P076F to fix?
Difficulty: hard. A typical repair takes 0.5 to 14 hours of work. This is a job for a workshop.
Will P076F clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
