    Whenever you see a code for gear ratio it means the transmission is internally slipping. The sensors see the difference between engine rpm and trans internal shaft rpm as a gear ratio problem....Needs to be rebuilt.

Replace the transmission (gear ratio codes are 'absolute')... your transmission is unserviceable.

2000 Elantra GLS with PO 732 and PO 734 codes. Any hope of a repair without a complete tranny rebuild?


2nd and 4th gear ratio codes. No matter the cause, the transmission has to be pulled. Low end at a garage is $1000, top end $2500+.

2006 sebring touring Error codes


I would start with the fluid level and condition. 731 & 732 are improper gear ratio for first and second gear. 720 is faulty output speed sensor, which makes sense with improper gear ratios.

Check engine light po 731


Diagnostic Test Code (DTC) P0731 is a transmission fault code and has a generic description of "GEAR RATIO ERROR IN FIRST GEAR".

The Powertrain Control Module (PCM) monitors the input shaft speed and the output shaft speed of the transmission through the input and output speed sensors. The proper gear ratio will produce a predictable difference between the two sensors. This DTC sets when the expected difference differs greatly from the actual difference between the two speed sensor readings.

This can be caused by several things including:
> Defective input speed sensor
> Defective output speed sensor
> Defective connections or wiring between either speed sensor and the PCM
> Shorted speed sensor circuit
> Open speed sensor circuit
> Slipping clutches inside the transmission

Please note that Transmission Control Module (TCM) replacement WILL NOT correct for this code.

The speed sensor data must be monitored with the proper equipment and the speed sensor circuits must be verified for proper function to determine the actual cause of this fault.

Ford trauras trouble code 732 - was told transmission code 732 was being produced, what does a code 732 say?


P0732 FORD - Incorrect Second Gear Ratio
Transmission in second gear and the ECM detected an incorrect gear ration. 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. In case the ratio exceeds the specified value, TCM judges this diagnosis malfunction.

Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Incorrect transmission shifting

Possible causes
- Low transmission fluid level
- Dirty transmission fluid
- Shift solenoids
- Transmission mechanical problems
- Transmission hydraulic control circuit

Tech notes
Start by inspecting the transmission fluid level and condition, and change fluid if necessary.


Hope helps.

What does the po 732, 733 and 734 codes mean on a 2002 Chrysler Pt Cruisier?


It means that your input and output shaft speed sensors see an error in the 2nd 3rd and 4th gear final drive ratios during the driving of the vehicle.

Code po734, po735


This is what your codes mean:

Trouble Code-P0734 (A/T Additional Gear Ratio Error In Fourth Gear)


Trouble Code Conditions:
Vehicle driven to a speed of 4-37 mph at more than 500 rpm, gear selector in 4th Gear in Drive, and the PCM detected too much difference in the engine speed and output shaft speed.

Possible Causes:

  • Customer may complain of intermittent 4th gear operation
  • O/D and 2/4 pressures less than 75 psi
  • O/D or 2/4 clutch volume indexes out of specification
  • O/D accumulator seals are damaged
  • Transmission enters "limp in" mode running in 4th gear

Trouble Code-P0735 (A/T Gear Ratio Error Fourth Prime)

Trouble Code Conditions:
Vehicle driven any forward Gear, and the TCM detected the ratio of the Input speed to the Output Speed did not match the current Gear Ratio (this test can take up to 5 minutes).

Possible Causes:

  • Related Gear Ratio trouble codes may be stored (note that some of these Gear Ratio trouble codes may be intermittent)
  • Transmission has internal problems or damage present
You have a transmission problem.
