The codes usually indicate a bad sensor or something, if everything is working properly then you will not get a code. Need the codes defined and see which sensors they are related to. I always carry mine to Auto Zone but I think Advanced Auto Parts will also read the codes for free and tell you what they mean. I would happen to guess that other auto part stores do the same thing. I use Auto Zone because where I live all the workers are all trained mechanics.

SOURCE: fault codes P0722 and P0717

You just need to replace the sensors. If you are mechanically inclined, you can do it yourself. If you don't feel comfortable working on an expensive transmission, take it to the dealer.

SOURCE: tranny does not shift out of O/D and starting out in 2nd gear.

Same situation, Solenoids in the Transmission were throwing the codes, Lost O/D and had transmission replaced. No signs of problems after check engine light came on for close to 1000 miles later.

Hi

Well two of the tranny codes ; P0734 and PO732 indicate gear 2,3,4 ratio incorrect. This can be caused by poor readings at the input and output speed sensors or pulse generators. The P1709 code is in reference to the kickdown servo switch.

Replacing the pulse generator set and TCM reprogramming( as per TSB) may solve your problem, otherwise you have a major component failure in the transmission unit. I would get some line pressures at the transmission checked first.

Sounds like the transmission is in fail safe mode, this happens when there is a transmission fault, you only have two gears 2nd and reverse.

Hope this helps - Steve

Definitivelly the trans is going bad and slipping. Thats what the codes mean. Theres not much that can be done from the outside. If you choose to fix it, id go with a good used to keep costs down. You can locate one at www.car-part.com

All codes
are for the trans slipping. If a sensor was out, you would have certain codes that say which one. For instance if a speed sensor was out, you couldn't have the two codes you have now as the speed sensor has to work in order to generate your codes now.

I would check your fuses. Check the connector to the transmission check the harness for any chaffing against the trans case where the wires could be shorting out. If all of that looks okay I would check the internal harness by removing the trans pan then replace the valve body which includes all of the solenoids. If all of that doesn't work its an internal failure and the trans must come apart for inspection and repair. As a rule of thumb if its intermitant its probably electrical if it does it at all times it could also be internal.

Keep us updated.

I have a 2012 Dodge Avenger that is showing the codes P0732, P0733, P0734. The rpms go up even when not accelerating. And then it won't go into gear. When it's in Drive it's like its in Neutral.

Those codes indicate the PCM/TCM has determined an incorrect gear ratio for 2nd, 3rd, and 4th gear respectively. That's because it is comparing the signals from the input speed sensor and the output speed sensor on the transmission, and one or both of them is not providing an accurate signal. I would guess that one (or both) has failed and needs to be replaced.

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
