So I recently moved from Washington to Illinois (that's a different thread) and before I left I put a 5 position chip in my truck, installed a transmission cooler and changed the fluid and filter on the transmission. I was pretty happy with the improved shift points, it's still a little lazy on shifting for my liking, but as my transmission guy in Washington said, it works pretty good for a transmission that is far beyond the typical service life
During the cold spell over the last couple weeks, I've been leaving the house at below zero in the morning, unless I really warm my truck up, my torque converter doesn't seem to be locking up for a mile or two. It shifts ok, but I definitely have no lock up, so I've been trying to warm the truck up but the truth is at -10 it doesn't seem to get very hot until you put it in drive. The transmission functions just fine and locks up just like its summer once it's up to temperature (I'm pretty sure my cooler isn't helping me right now ), and I'm pretty sure this is a result of the sub zero temperatures, but I figured I'd ask the E4OD experts on here just to double check.
As always, thanks for any input.
