What Does P076F Mean?
The TCM has detected that the gear ratio in 7th gear does not match the expected value. When the transmission is commanded into 7th gear, the actual ratio measured by the input and output speed sensors does not correspond to the correct 7th gear ratio. This indicates slippage, incorrect gear engagement, or a mechanical failure within the 7th gear clutch circuit.
Common Causes
30%
Internal clutch pack or band wear for 7th gear causing slippage and incorrect ratio
25%
Shift solenoid malfunction preventing proper 7th gear engagement
20%
Valve body wear or stuck valve in the 7th gear hydraulic circuit
15%
Low transmission fluid level or degraded fluid reducing clutch apply pressure
10%
Input or output speed sensor malfunction giving incorrect ratio calculation
Diagnostic Steps
1
Monitor input speed, output speed, and calculated gear ratio in live data while the transmission shifts into 7th gear to quantify the ratio error.
2
Compare the actual 7th gear ratio to the manufacturer specification — determine if it is a slip condition or completely wrong gear engagement.
3
Check transmission fluid level and condition; low fluid reduces clutch apply pressure and causes ratio errors.
4
Test the shift solenoids that control 7th gear engagement using a bi-directional scan tool.
5
Check input and output speed sensor readings for accuracy by comparing to known vehicle speed.
6
If solenoids and sensors check out, the issue is likely internal mechanical failure requiring transmission disassembly.

The most common cause of P076F (Gear 7 Incorrect Ratio) is: Internal clutch pack or band wear for 7th gear causing slippage and incorrect ratio
Typical repair costs for P076F range from $300 to $3,500, depending on the vehicle, location, and whether you do it yourself or go to a shop.
The transmission may avoid 7th gear or slip when in 7th gear. Driving at lower speeds using lower gears is possible, but the transmission is at risk of further internal damage. Have it inspected as soon as possible.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P076F to identify the root cause.
