Customer Question

My 2012 dodge avenger is throwing a p0733 and a p1790. The car shifts fine from first to second but acts like there is no third gear. Downshift between first and second is also smooth. I am just trying to get an idea of what the problem might be before I take it into a shop for repairs. Have not noticed any slipping, just no shift into third. My car drove absolutely perfect yesterday before I got in it this morning to find this.

Incorrect ratio codes (p1790) almost always indicate a mechanical failure in the transmission, but they are almost always accompanied by slipping. I think you are on the right track with disconnecting the battery to try and reset the TCM. It could be setting a false ratio code. At this point it might be best to have it towed to a transmission shop since you might not be able to get the TCM to reset without pulling the battery cable.

Did you try to remove the transmission control relay yet?

Here is a picture of it's location.

If this relay were bad you wouldn't get 1st or 2nd gear, only 3rd. Since you have 1st and 2nd and no third, I hate to say it, but you probably have an internal mechanical failure and will need a transmission rebuild.
