I don't think you can, not unless you change the tranny again for the correct one

dont listen to this guy never flush your transmission thats a quick way to kill it. do a pan drop fluid filter change. refill with dexron 6. but ill tell u now ur problem is most likely the PRESSURE CONTROL SOLENOID in your transmission. may or may not throw a CEL. causes harsh shifting and slipping etc very common on the 4t65e trans. can happen any time and usually symptoms most obvious when engine reaches operating temp

Sounds like the PRNDL switch on the side of the transmission. Be sure and clear the code before trying to start after replacing it.

I have a 2002 kia rio and my check engine light came on the dianost said the problem was 4th gear incorrect ratio! What does that mean?


The purpose of the automatic transmission is to match the engine's optimum power and torque characteristics to the driver's desired rate of acceleration and speed by auto-selecting different gear ratios or 'speeds' to power the wheels.

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

Incorrect gear ratio code is coming up. How do I fix it?


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

I have a 2001 vovlo s80 with the codes p1618 p0705 po733 how can i fix


PO705 is Transmission Range Sensor Circuit Malfunction. PO733 is Incorrect 3rd Gear Ration Information. P1618 means that the ECU and the TCM are not communicating properly. PO705 & PO733 can be related to P1618. Check the wiring going to the transmission. Look for a pinched wire from the car being put on a rack or possibly an accident you may have had recently. If you can find no problems with the wiring or connections then it is time to see a professional transmission expert. It may just be that the transmission has an internal problem.

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.

My 2000 Saturn sl1 recently showed codes po733 and po734.What exactly does this imply and where would I start if I wanted to try fixing the problem myself?


po733- gear 3 ratio incorrect, po734- gear 4 ratio incorrect. this is how to fix. You can try replacing the shift solenoids inside the transmission as long as the trans fluid is nice and clean looking. If the trans fluid is dark or burnt looking, it time for a new tranny if you need further assistance please let me know and i will be glad to assist you. Thanks, Midwest-Tek

Vehicle wont change up into gear reverse gear not


P0734 - 4th gear incorrect ratio. P1529 Malfunction Indicator Lamp Request. Problem is in the transmission.
Take/Tow your vehicle to an authorized Hyundai dealership and pay the diagnostic fee... they will tell you exactly what the problem is and the cost of parts/labor to fix it... at least this way you'll know what the problem is and what's required to fix it.
