So how do we fix it? This is one of the main problems with the T&C. What issues is it that your having? What codes what symptoms?
As for why no one on here has a clear answer to the issue that your having? Well maybe its not the same as everyone else. Maybe just maybe yours has on of the other related possibilities what the code your asking about. Main assumption I get all the time when asked about a check engine light.
A- just because the word speed sensor,oxygen sensor,map ect what ever sensor is listed in the description does not mean that the sensor has an issue. Codes are simply a way for a tech to start looking in what area.

B Web forums will fix everything. Also not true, Just about every situation is not the same and unless you have had someone look at the issue at hand it may not be the same. Web forums like that are a source of information and ideas, on what could possibly be the issue, where to go look what others have seen and done. Its not the bible nore should it be taken as such. So complaining why someone on here has not fixed your certain issue and tell you what to go replace is kinda asinine.
If your willing to put in the work and perform what tests as asked of you several of us on here will help out when available. My knowledge did not come free and i dont freely offer it unless the one receiving it is willing to put some work into it and is gracious for such info.

They had it for 1.5 weeks and could find nothing but the wires I had bypassed during my troubleshooting. I had them rewire the sensors and they then suspected the TRS(Transmission Range Sensor) switch because of the instrument cluster indication. They asked me if the Compounder was replaced during the rebuild and I informed them that it was rebuilt but not replaced. They then pull the side cover off to look at the TRS and wiring. When the pulled the cover they said that they found chips in the pan and that it looked to be coming from the Compounder. They siad the the wiring looked ok and gave me an estimate for a Compounder inspection. I called my transmission mechanic(He rebuilt this trans) and he suggested that I bring it back to him because, "you hired me to do the rebuild and I should complete the work". That kind of integrity is rare nowadays, but I digress. My trans mechanic pulled the pans and could find no evidence of chips or fuzz. He proceeded to pull the tranny and go through it to ensure no contamination existed. He then pulled the Compounder out and apart and it looked like new. He mic'd out all the components and checked for warpage but the compounder was perfect. He had another rebuild kit in his shop and he rebuilt the compounder for a second time, just to be sure. He put it back together and replaced the TRS while re-assemling it, to fix the boxes around the trans position indication on the instrument cluster. (the indication problem started after the transmission rebuild, so my trans mech said he would replace that part antway as he did not catch that problem when he test drove it after the rebuild) When he went to test drive the van, the boxes around the indicators were still there. A little frustrated he went back through what he did on the original rebuild and he noted that he had replaced the solendoid body as a possible cause for the transmission codes(P0734 & P0792) I had been getting. Since all the signals from the TRS go throught the solenoid body connector he put a new solenoid body on my transmission and this fixed the indication issue. he then test drove the van and the P0734 & P0792 codes did not reappear. He drove the van for 10-15 mile with no problems (these codes would set within 5 miles everytime before). I picked the van up on Christmas Eve and it has been working great for the last week. So it looks like the P0734 & P0792 codes were corrected by the replacement of the TRS. As unlikely as that sounds, it is the only part, that was changed, which caused a change in the trouble codes.
If the TRS was the problem then I wonder how many remanufactured transmission were replaced for this simular issue, as a remanufactured unit would have a new TRS installed?
$4000.00 fix for a $30.00 part?
I am just happy that my T&C is back on the road and I will update should this problem rear it's ugly head again
