You would need to get the actual trouble code and the diagnostic info to troubleshoot it. The most common problem is a sensor failure or wiring problem. The transmission is telling the computer the wrong gear is being used.

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

There is no one fix works for all on these code. Also you have left out the letter and one number of the code I assume these are P0730 and P0733, if so read on.

P0730 CHRYSLER - Incorrect Gear RatioPossible causes- Low transmission fluid level

- Transmission mechanical problems

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.

Transmission Problem - Ford Escape 2006


P0732 and P0734 indicates gear ratio errors in 2nd and 4th gears, basically no 2nd and 4th gear. The one thing 2nd and 4th gear has in common is the band, the band is known to break, this is a common failure with this transmission and happens on a regular basis.

You need to remove the transmission to repair it.

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.

P0734 Incorrect 4th Gear Ratio
P0736 Reverse incorrect gear ratio


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.
