So my trans has been working good since I changed the fluid and adjusted the kickdown linkage. I've noticed when I first start the truck up when it's cold it doesn't wana go when you put it in gear. You've gota give it some gas. Once it gets moving it's good. Its just that first takeoff after startup. I've noticed this getting worse lately. I'm curious if there's anything I could do? Or could a trans flush do the trick? I know when i drained the fluid and changed the filter I only got about 4 quarts and the trans holds like 10?
