When I first start the truck in the morning, I put it in reverse, and push the throttle, the truck moves, but almost like it doesn't have the normal amount of power. If I let up, then go again, the truck moves in reverse normally.

This only happens when it's cold out, and I wonder if the fluid is just not circulating well quite yet?

No warning lights that I know of, the fluid is full and clean, doesn't smell burnt.

Second thing, my brake warning light, and occasionally my RABS warning light come on occasionally, and the truck acts exactly like normal. Brake fluid is full, nothing outwardly problematic. Any thoughts on that too?

Might just be a delayed reverse reaction. Stock E4's are known for this. If the delay is real long, the converter could be draining back. This would be a dirty check valve.

My ABS acts the same. You can pull codes for help. Might be rear axle sensor or the tag harness from axle to body, takes a lot of movement.

How many miles on the tranny. Sounds like the seals are bypassing when cold.
