Transmission fluid circulation
After I start my truck on these cold Wisconsin mornings and let her warm up a few minutes, does it help to keep it in gear as far as the tranny fluid circulation? Does the fluid circulate as much in gear as it does in neutral? I'm trying to warm up the fluid as much as possible before driving. This is on an automatic.

The fluid will circulate less in gear at idle because the idle speed drops. It will heat up faster in gear because the torque converter is slipping. I wouldn't wait to warm up the tranny fluid it will warm up as you drive.

Mine takes forever to shift or lock the TC when cold. Is there a way to bypass this or is it there for safty or something. Kinda a real pain since you cann't push the throttle real hard when its cold.

I think its retarded. My buddys trucks locks in miles before mine does. Does the trans circulate fluid all the time to the cooler or is it a temp thing?? Could mine be sticking and curculating all the time taking longer to warm up??
For custom tunes, do you mean through Jody and the DP tuner, or the bts?? More of a reason to save and set one.

The 4R100 always sends fluid to the cooler. There is no thermostat.
As for custom tunes, I don't know anything about any of them. All I know is what is in the stock tune, and that one has screwy cold weather operation. It would take some custom programming to change it.
