Transmission Failure???
Hey everyone, so I was hauling a trailer this morning with my 2002 F-250 7.3 diesel. Going down the highway apparently my transmission overheated and all the fluid came out thus leaving me stranded on side of road. It was towed to local shop and they put more transmission fluid in and were able to drive it. The codes p0743 and P0741 came up. They trying to tell me I need a new transmission. Aren't those codes for the clutch converter and a solenoid?? It's tough because I need this truck back up and running asap! Anyone have experience with this?
thanks!
thanks!

My take on this is the P0743 code is from the root cause of your problem. That code sets when there is an electrical circuit error in the converter clutch solenoid circuit. It could be a bad solenoid or a damaged wire between the PCM and the solenoid. It takes some hands on diagnostics to determine when one is the problem.
The P1741 just says the converter didn't lock when the PCM wanted it locked. That's a result of the electrical problem. The overheating is a result of the converter clutch not locking.
So if you find and fix the electrical problem everything should be fine, unless the overheat was so severe it damaged the trans. And that takes well over 300°F to accomplish.
A new trans might fix this. The electrical problem could be outside of the trans. You could just have a damaged wire.
