We have the 47e automatic transmission on our 99 Dodge Cummins... purchased with around 150K and we just rolled over 200K... When our truck was in the shop around 175K I asked our mechanic to flush the transmission and he was hesitant since we did not know whether the prior owner had regularly changed the fluids. Any thoughts? We are currently experience the torque lock problem around 45-50 mph that is addressed in several other posts on here... so we are going to replace the alternator in the next few days... So any other suggestions on preventative measures to prolong the life of our transmission would be great! Thanks

I asked this on a few other boards, but figured I would ask here also. I bought my Cummins about a month ago, It drove perfect. The motor is stock, and I had thought the transmission had been rebuilt at some point due to how nice it shifted and how much cleaner the transmission was comapaired to everything else under the truck. Not long after I got the truck, I desided to check the fuel pressure. I bought a cheap-o oil guage from the parts house and used one of the test ports on top of the fuel filter housing. Well My lift pump is only putting out 10psi at idle, and Zero at WOT. So I figured i would take it over to my father house to park it. (more space) Its a 5 mile trip over from my house, and on the way over the torque converter would not lock up. The transmission shifted like normal,just not converter lock up. I have not drivin it since then. I am trying to keep any further damage from my VP$$.I reason tell you all that to ask this.. Is there anything I could have bumped, or knocked loose wile I was messing with the fuel filterhousing? Before this, it shifted perfect. It would lock in at 42mph and not budge unless I slowed down, or got on the trottle heavy. I checked the soliniod and it was 30.5 ohms. On the other boards I am beening told my converter/ transmission is shot. I leave for Basic training in january so I dont plan to do anything to my truck till I get back in june. Any Ideas or things to try would be awsome. If in fact my converter is shot, thats cool too. I just dont want to jump the gun. Thank guys

I recently bought a 02 Dodge 2500 4wd auto, bone stock w/ 58,000 miles. I was driving it today and it won't stay in overdrive. About 55-60 mph or 1500-1700 rpm seems to be the worst about kicking in an out. I was on flat roads maintaining a steady speed. I'm new to auto transmissions behind a Cummins but this don't seem right.Help or suggestions appreciated.

When I first hooked up my mystery switch it worked great. Now it locks the convertor for maybe half a minute then it unlocks and I have to turn the truck off before it will work normally again. Gives me p0723 code which I had before too when it worked normally. p.s. I took the switch and wiring out when the truck went to the tranny shop for the rebuild cuz I didn't want them down my throat for using it. This problem occured after I got the truck back and rewired it.
