P0732: Gear 2 Incorrect Ratio
Can you still drive? Not recommended. Second gear slippage will worsen over time and can lead to complete transmission failure. Have it inspected immediately.
What Does P0732 Mean?
Code P0732 indicates the TCM has detected an incorrect gear ratio in 2nd gear. This means the transmission is slipping or not fully engaging when commanded into 2nd gear. Second gear is heavily used in city driving during the 1-2 upshift, so wear on the 2nd gear clutch components is relatively common in high-mileage vehicles.

Frequently Asked Questions
Is P0732 a death sentence for my transmission?
Not always. Sometimes a fluid change, valve body repair, or solenoid replacement can resolve the issue. But if the clutch packs are severely worn, a rebuild may be necessary.
Why does my car jerk during the 1-2 shift?
When 2nd gear clutch packs are worn or not getting enough pressure, the transition from 1st to 2nd is rough because the clutch cannot engage smoothly. The RPM may spike momentarily during the shift.
