Transmission.
Alright so for a while now my transmission will get stuck in 2nd gear when the truck is cold and because it is cold outside. Nothing out of the ordinary, just let off of gas and it will shift. But lately it has REALLY been getting stuck! Even for a long time after it is warmed up. Is it because it is really cold out or is it a sensor of some sort??? I even stay lightly on the gas and its gotten up to close to 4,000 rpm's and wont shift. And now lately it has also been acting like it is getting confused or something. When it gets stuck, every once in a while it will shift down to 1st and up to 3rd and then back into 2nd. :/ While warmed up too. This all happens while town driving.

Get yourself one of these http://www.doghousediesel.com/catalog/i307.html And use ATF+4 fluid only when you refill. Get a drain plug for the tranny pan also.

The screens on the solenoid could be clogged, or the little block assembly thingy could be clogged too.
The BW Solenoid is a good bit larger than the stock one.
I did this upgrade the other day, Tuesday I think.....
And it's quite simple to change, drop the pan, 4 bolts & 2 torx screws, unhook the clips for the solenoid and pressure sensor and walla. Easy peasy.

+1 on govenor pressure soleniod... clean it or replace it with the borg warner unit... I have done mine twice now and the second time around I had to had the tranny rebuilt but went with the borg warner solenoid. If you ignore it you will end up only having 2nd gear as the truck will eventually go into "limp home" mode and not shift any higher... been there.. If the screen is plugged solid with shavings its a good warning that you might want to prepare to replace the transmission or truck (which ever is cheaper).

I had similar problem when cold, always good when warm. Could force shift by manually putting in 2nd and then back to drive, that always makes shift even when freezing out. I changed fluid and filter, used ATF +4 and added drain valve. After a few hundred miles, I drained fluid and added new ATF +4. It is doing much better, but not perfect. I may do one more fluid change or might just do as suggested here and switch out sensor and solenoid? I have read and reread those instructions in TV adjustment, the terms in manual (one from this site) just don't match pictures in manual figures and pictures a little different than what on truck. I bet the TV adjustment is easy, but for some reason I get mental blocks on it, need to see someone do it. The shift into OD works perfect.
