So last week my 2007 dodge 1500 lost its third gear. I brought it to the shop and they immediately said the transmission was shot. Luckily I had a buddy with a transmission for me with only 10,000 kms on it. But after putting in the new trans, I’m getting the same result, no third gear. Getting codes P0869, and P0733. I also noticed when I put it in drive and reverse there was a delay before it kicked into gear. I then plugged out the speed sensor on the passenger side of the tranny and with it plugged out I got immediate response into drive and reverse, but still no third gear. Anyone experienced something like this?

 

The first code is for high line pressure. Is there a switch or sensor in one of your lines? I might try swapping that out? just a guess tho

 

Not that I’ve seen but I’ll check that out, thanks! Shouldn’t be a sensor cause I didn’t use any of the old sensors over

 

So take all of this with a grain of salt. Just guessing cuz your issue grabbed my curiosity. If you swapped all sensors...including a malfunctioning sensor you may have transferred the issue to the new trans?? Maybe a defective line sensor is creating an issue where the computer will not allow 3rd gear ??? Only throwing this out for consideration. This might help

If pic below is correct #4 may be your line sensor

 

Sorry. Just read your response again and I seen where you didnt reuse old sensors....

 

Yeah I don’t think it’s a sensor, but it could be a wire issue going to the sensor I’ll have to check that out!
