Extreme cold transmission shifts

[MrVeteran51248]

No too worried but has anyone else had this happen to them? Driving to work today started the truck at -20 f to warm for 20 min or so. Then left, as I was driving I noticed it taking longer to get into the next gear. I assume this is from the almost solid transmission fluid. But even after 5 miles, the trans didnt want to shift into 6th. I could manually, but as soon as i went back to D it shifts down. No problem last night, also it seemed to act like it was in tow mode for the shifts. Is this just from the extreme cold? Or will i be expecting repairs soon?

Common on my Fords & GM when cold in north east here in Florida it never happens .

Very common until fluid has a chance to warm up some.

the trans fluid doesnt warm up like engine oil when remote starting. it has to be driven to heat up. delayed shifts happen occasionally.

-20° is a pretty extreme low for any vehicle.

Yeah, I feel like every vehicle I have ever had, car, truck, bike, mower, side by side all universally don’t like sub freezing temps, almost on par with me. Everything. Ducati 1198s, ZX11 with undercut gears- 2 of the best shifting bikes I’ve ridden - even they were notch in 20’s or lower when I lived where humans weren’t meant to and regularly used electric gear.

I've seen in the trans tuning tables, there are shift settings based on temperature. Just watch your trans temp on the gauges menu. When it gets up above 80 degrees it should be close to normal shifting. With the drag from cold differential and transfer case fluids it will feel like your towing something light, probably why it takes longer to shift.

About what I was thinking / hoping. Normally, i wouldn't work in such extreme temps, but I changed jobs.
