This means the trans is slipping as measured by the input and output shaft speed sensors.

Ihave code p0731 stuck in 1st ratio .. what mean that code?


obviously refers to auto trans , could just need the trans fluid level topping up or even changing , if this does'nt resolve the problem then a more in depth diagnosis would be required at a repair shop as could be the ECU for example but do the fluid checks and go from ther ,keep me posted

Now i dont know a lot about automatics especially modern ones with all this fancy electronics thats used nowdays but i think its a fault with the temperature sensor for the gearbox.But where its located and what it looks like i have no idea it could even be mounted inside the gearbox .Sorry not a very good answer from a mechanic but?? very few of our europeon cars come with auto transmission .Evan when i do know whats wrong i cannot buy the parts for the gearbox as only re-con boxes supplied by the dealer so best advice is to try a specialist in auto box repairs only .PS some of my best students when i used to teach mechanics many moons ago were the girls so no excuses like iam only a girl please

My 2000 Sephia will only shift gears manually from 1,2, then to drive. I get a code PO734. How do I fix and or slove this problem?


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.Hope this helps, James Booth

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.

The diagnostic codes are: PO 722 output speed PO 732 Gear 2 ratio PO 734 Gear 4 Ratio What do these codes mean>


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

I took my 2007 vw beetle into a shop and the guy said it was a transmission code po 730. What does that mean and how much will it cost. The car works fine its just when I stop at the stop light and start...


code p 0730 refers to incorrect gear ratio===causes --wiring---R ( transmission ratio) sensor /switch---shift solenoids--transmission mechanical fault
you say that the transmission runs well except for the jerk so the transmission is good
It indicates that the TR sensor is faulty so take it to an accredites auto transmission specialist shop for a proper diagnosis and quote to replace the TR sensor

Trans problem


Hi, the premium system was just revamped and currently is having a little problem of not letting me post a solution to your premium question but I figured I would post the answer here for now until the problem is resolved. Sorry for the inconvenience and the time it has taken.

The codes you have are all gear ratio error codes fordifferent gears. The most likely cause to see all of these codes together wouldbe an input or output speed sensor. If your speedometer does not work, replacethe output. If it does work, I would recommend an input speed sensor. Thiscosts about $25 and is easy to replace. The speed sensors are on the left side of the transmission. You willneed a 1" socket to replace them. Let me know if you have any furtherquestions with this van. We have actually owned a few of these, so prettyknowledgeable with them.
