From a cold start and if it's during the first 10-20 minutes of driving it could be due to the fluid not being warmed up.

Afetr about 2 min of driving I am on the highway. I will hit 90-100 for a min or 2 then she locks up. In the summer well it would happen right away. I have been watching my temps on my gryphon and it seems when the tranny hits around 100 it locks, but not before.

I think your numbers are normal and I'm pretty sure the 90-100 you are throwing in represents kph, not mph (which would be about 55-60 mph), right?
In the winter, even here in Tucson, where I live it regularly goes below freezing in the early mornings and if I take the truck out it takes about a minute for things to warm up enough for the TQ to lock up. You're probably operating in "open loop" during that period too, for what it's worth. - Jack

There are both cold and hot TFT strategies for the converter lockup. This is where the difference is that your feeling and it's completely normal.
