Warming up tranny fluid

I don't have anywhere on base to plug my truck in so now that it's cold I start my truck in the morning and let it run while I get ready. I was told that I had to put the truck in neutral to get fluid to circulate through the trans so it can warm up too. Is this true? I'm completely transmission stupid.

i think we have the same problem. My truck wont shift in the cold mornings.

I'll get it in put it in drive and it's like it doesn't go into gear...then a second later it slams into gear

Yes that is true. When I let my 07 sit for a while (3+ days), the TC drains and it won't shift into gear straight from P. It'll just sit there in D and not move until the fluid pumps back in. If I start it and put it in N and let it sit for 15-30 secs while I put on my seatbelt and wait for the wife to get it, it'll go once I put it in D.

And while not moving with it in D or N (stop light or in traffic), the tranny temps continue to rise. In P, they don't.

I never have any issues with mine in cold. I just start it and drop in drive and start my way away without any issues. Make sure the fluid is good and the filter isnt clogged (cold=thicker fluid)
