When cold, truck transmission seems to slip when shifting - I think from low to second gear. If I give it the gas in this situation, engine speeds up but transmission appears to slip so I get no speed increase. I've had the fluid and filter changed and transmission shifts fine when it warms up so am wondering if there is a fix for this cold-engine situation. Thanks.

Let it warm up a little bit on especially cold days
I too am interested to see what people say here

In my opinion, you may need to step up the quality of fluid. My truck doesn't like supertech or stuff on that level. I stepped up to Maxlife ATF and all my shifting issues went away.
