P0732 Subaru Code - Gear 2 Incorrect Ratio
Quick Answer
This diagnosis monitors actual gear position by checking the torque converter slip ratio calculated by Transmission Control Module (TCM) as follows: Torque converter slip ratio = A x C/B A: Output shaft revolution signal from revolution sensor B: Engine speed signal from Engine Control Module (ECM) C: Gear ratio determined as gear position which TCM supposes If the actual gear position is higher than the position (2nd) supposed by TCM, the slip ratio will be more than normal. Common causes include Low transmission fluid level, Dirty transmission fluid, Faulty Shift Solenoids. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0732 Subaru Description
Torque converter slip ratio = A x C/B
A: Output shaft revolution signal from revolution sensor
B: Engine speed signal from Engine Control Module (ECM)
C: Gear ratio determined as gear position which TCM supposes
If the actual gear position is higher than the position (2nd) supposed by TCM, the slip ratio will be more than normal. In case the ratio exceeds the specified value, TCM judges this diagnosis malfunction.
What are the Possible Causes of the DTC P0732 Subaru?
- Low transmission fluid level
- Dirty transmission fluid
- Faulty Shift Solenoids
- Shift Solenoids harness is open or shorted
- Shift Solenoids circuit poot electrical connection
- Transmission mechanical problems
- Transmission hydraulic control circuit
How to Fix the DTC P0732 Subaru?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.

Frequently Asked Questions about P0732 Subaru Code
What does the OBDII code P0732 mean for a Subaru?
The code P0732 indicates that the transmission is detecting an incorrect gear ratio in second gear, which may be caused by mechanical or electrical issues.
What are common symptoms of the P0732 code in a Subaru?
Symptoms include poor acceleration, slipping in second gear, harsh gear shifts, transmission overheating, and reduced fuel efficiency.
What causes the P0732 code in a Subaru?
Common causes include low transmission fluid, worn clutch packs, damaged solenoids, faulty sensors, or internal transmission issues.
How can low transmission fluid cause the P0732 code?
Low fluid can lead to insufficient hydraulic pressure, preventing the transmission from engaging second gear properly and triggering the code.
Can a dirty transmission fluid filter cause the P0732 code?
Yes, a clogged filter can restrict fluid flow, reducing pressure and affecting gear engagement, potentially leading to the P0732 code.
How is the P0732 code diagnosed on a Subaru?
Diagnosis involves checking the transmission fluid level and condition, inspecting solenoids, sensors, and wiring, and performing a transmission pressure test.
Can driving with the P0732 code damage the transmission?
Yes, continuing to drive with this code can worsen existing issues, potentially leading to costly transmission damage.
How do you fix the P0732 code on a Subaru?
Repairs may include replacing the transmission fluid, fixing solenoids or sensors, repairing wiring, or rebuilding the transmission if internal damage is found.
How much does it cost to repair the P0732 code on a Subaru?
Costs vary widely depending on the issue, ranging from $100 for fluid replacement to several thousand dollars for a transmission rebuild.
Can the P0732 code be cleared without fixing the problem?
You can clear the code temporarily, but if the underlying issue remains unresolved, the code will likely return.
