Hello,
I would like to see if I could help with this situation of the cold wows. First if his Durango is a V6, it has a 42RE. If it is a V8, it has the 46RE. They work the same just one is bigger than the other. OK then, 1996 and up done away with the mechanical governor in the trans and went to a electronic gov setup, which consist of a gov pressure solenoid and a gov press sensor. The gov press sensor is also the trans temp sensor. With all that be said, it feeds all this back to the computer, such as trans temp and gov pressure. The computer then know what fluid temp is so it does not dump the trans into OD and lockup to put the load on a cold motor. This would cause the motor to lug down, spit sputter until it gets warm. Unless the shifts are late enough to red line the motor, I wouldn't worry so much about it, because the computer sees what is going on and controlling everything. I hope this helps.

When the dodge durango 1st came out in 1998, it only had a 4x4 transmission, then 2000 came the 4x2 and 4x4, the 4x2 has a 44RE trans and 4x4 has a 46RE. But also 2000 start the 4.7 engine and the 45RFE trans and later had a software update to make that trans a 545RFE.2004 was a new body for durango and then had the 3.7 and 4.7 The colder the weather the transmission will take longer to flow thru the box, and you could have some drain back on your transmission, This also cause the transmission not to move until the front pump build up some line pressure. Also with cold weather you may only get 1st and 2nd gears until you reach engine temp. If this happens move your shifter to 2nd, this will allow just 1st and 2nd gears, then after a few min put the shifter back into overdrive.
