2 questions. 1) I've heard that a lot of dodge trannys don't circulate fluid while in park. If it's not moving, does it have too? & 2) would letting it idol in N be better? (as in northern climates) Thanks for the help!

 

Haven't tried it in park, but even in Neutral the fluid doesn't circulate until you kick it up to about 1500-2000 RPM. That's been my experience at least.
