2011 Outlander SE Fault Code

Hello,

I just purchased a 2011 Outlander Sport SE with 91,000 miles for a family member. I took it for a test dive and it drove great. Once I went back to the local dealer and signed all the paper work while I was driving it home the Service Transmission light on the dash came on. Once the car was turned off and back on the light was gone. I was planning on taking it to a Mitsubishi dealer in town and having an oil change done the next day, so I asked them to do a diagnostic check on it. The tech called me back and said he had bad news. He pulled a (P1740) and (P1749), (B1477) and (B1476) codes. He said the code was an internal transmission fail. He said he drove the car around the building and the service transmission light came back on. He told me that the transmission needed to be replaced!! He told me that it was not worth tearing apart the transmission and that a rebuilt one was still going to cost thousands and may not be worth it due to the overall value of the car.

I drove it back to the small local dealer where I purchased the car and told them and gave them the paper the Mitsubishi tech gave me. They drove the car and said they could not find any codes and that I would need to continue to drive the car until the service light came back on and then bring the car back so they could see the code. the mechanic here said based on the code that it looked like some type of solenoid for the transmission or torque converter solenoid needed to be replaced and that it was simple.

so I have had this car for a total of 4 days and im scratching my head, it drives fine, no weird noises, no shuttering?!?!

is the P1740/P1749 fault code a simple transmission fluid/filter change and or simple solenoid fix

Or like the Mitsubishi dealer does the transmission need to be replaced?

I have searched the internet for the P1740/P1749 code and nothing I have read said the transmission needed to be replaced

any help would be great!

Let's assemble these codes. Here's the first one.

P1740 Dodge Description
Torque Converter Clutch (TCC) and Overdrive (OD) clutch are tested when the Powertrain Control Module (PCM) requests TCC engagement in 3rd gear and Overdrive. The P1740 code will set if expected RPM drop is not achieved while attempting to engine TCC and/or Overdrive.

And

P1749 Dodge Description
The transmission throttle valve cable has been replaced by the Transmission Throttle Valve Actuator (TTVA). The TTVA consists of an electric DC motor, two potentiometers, and a gear drive system. The TTVA is mechanically is connected to the transmission throttle valve in the valve body by the “D” shaped opening in the bottom of the TTVA shaft. The Transmission Throttle Valve Actuator (TTVA) does not require any mechanical adjustments. All changes in throttle valve position are controlled by the Engine Control Module (ECM).

So the transmission isn't perfect, but some parts will have to work harder to change gear smoothly. I'd leave it, but do get a second opinion!

It's important to manage the fault situation. For example if there were another code but you always left the engine warning light on then you wouldn't know about the new code would you? So get a cheap codereader, reset the codes every week, but note which codes are there each time you reset them. That way you will see if something extra comes up, which could be more serious!

Thank you for the info,

I spoke to the tech and they did clear the codes, they have yet to return. we are waiting for them to come back. The tech did say they looked at the trasmission fluid and said it looked "okay" a little dark and not great but not bad either. He told me that it should be changed every 30K miles. it just hit 91,000 so I am pretty sure the original owner did not do the 90,000 trans change. I was quoted 259.00 to do a change. I am wondering if we should start here?

I called another dealer and gave them the codes, based on P1740 code the tech said the valve body on the transmission needed to be replaced and that in a lot of cases they have just cleaned the "connector" hose and that it usually fixes the issue and the light does not come back on. They said its a large connector hose and take about 30 mins to do. Has anyone heard of this cleaning?
