TorqShift not shifting when cold - this normal?
Yesterday morning I pulled out and my tranny was stuck in 1st. 4500 RPM and going 10 MPH ... anyway I let off the throttle, it shifted, then it stayed in 2nd, same for 3rd. Never got into OD before the tranny temp gauge came up to normal. Later that day it seemed normal.
OAT was indicated at 18F on my mirror.

When it's cold out, it's important to take your time starting out until the truck warms up to a decent temp. I don't know about the TorqShift, but the 4R100 is programmed to delay shifts and lockout OD until things get warmed up inside the trans.
This may be what's occurring on your truck, but since you have an '07 I'd have the dealer check it out and make sure it's not anything serious in disguise.

No I was in a hurry so I just started and went. Return trip I started, went back inside, came out 10 mins later and drove away. No shifting problems there. I kinda thought the fluid needed to warm up a bit. I don't have a way to plug it in (live in apt) so it wouldn't benefit from the block heater.
Someday I'll put a remote start on there.

you would spin a cold engine to redline and beyond? do you keep your vehicles very long. i hope it was a life threating situation, thats the only reason i can see for beating an innocent truck like that. scuffed pistons and multiple headgaskets are the future if this is a habit
