Terry, Just a little tip I learned from one of the owners at Jasper engines on the 48re..
When I had my Dodge, I had it chipped, 90hp injectors, intake elbow, etc, etc. I had started noticing a slight hesitation when starting it in the morning, where it would wait for a few seconds before starting to move in the morning. After it started to move it was fine all day.
The guy at Jasper had told me to remove the check ball in the lines near the trans cooler. I did that and it the hesitation stopped completely, made a huge difference in how it shifted too. He also told me to run Royal Purple trans fluid, which after the pucker factor buying that, it was solid as ever and took about 100k miles punishment before I sold the truck, with the trans still fine.
Apparently the check valve hampers fluid flow with the plastic/rubber parts in it, and it starts causing wear. He said if dodge hadn't put those check valves in, they probably could've saved themselves a bad wrap on the transmissions..
