Haha well we will be there for at least a year. I sure will miss the out doors around here in Vegas but the city itself is a ghetto since the housing market crash. I have been surrounded by wanna be thugs since I got here. I have actually seen some real thugs come after my neighbors pushing their way into their house with a gun. I think they needed to change their pants after that. You wouldn't think my neighborhood was full of these types because it looks nice but Gov. gives out section 8 vouchers like halloween candy. They can get 1400 or more in free rent.

No big deal, I used to live and work on the Grand Canyon North Rim. I'm from the South East originally. Never though I would live near D.C. though. Can't say I'm excited. But hey more money. Out here I can drive 30 minutes and be in the middle of no where. I don't think there is much wheeling over there and stuff to explore. There are hundreds of ghost towns and old wagon trails out here to fool around on. Why did you move so fast?

Won't find anything like that in D.C.
If you like to take trips there are plenty of places to get lost and 4 wheeler trails in West Virginia.

I can attest to the fact that even if a tranny only gets up to 200 degrees (and no flow in OD unit sufficient enough to trash bearings) the OD frictions can incur significant damage. It was only at 200 briefly, but it appears that was enough. Friction material had consistency of charcoal....

I think that's a pretty old chart because ATF-4 can withstand temps up to 300* and maintain it's integrity. I would still change it anyways though. Temps of 250* sustained with ATF-4 are fine. I'm talking about fluid temp coming from the torque converter not internal transmission temp. But I am still wondering if anyone here has run into trouble with the radiator bypassed and having a large trans cooler with it running too cool? I don't even know what the effects of too cool would be. Isn't ATF-4 rated for 20* or something? I know it has superior hot and cold viscosity but I am not sure what the cold rating for it is.
I know my transmission heats to operating temp before my motor temp would help to heat it since it goes right into O.D. so far. I guess I will just see what happens with the colder weather.

Hey, I'm having an issue with my 98 ram 1500 5.9 mag RWD
My O/D light will not go off, my trans temp light is always on, and when stopped a a light or something my engine oil gauge drops down but it'll jump up when I accelerate... the issue with my o/d issue that my trans thinks it's hot, I believe and will not allow my o/d to turn on. I've gotten the trans rebuilt with a stage 1 pro shift and tow package by a shop.

Did your trans problem start shortly after the rebuild by any chance?
Oil pressure is a separate problem. Chances are good, it's just failing sending unit. They are fun to change though......

But anyway, this no o/d and trans fluid temp light being always on, no. These were problems after the rebuild.
