Ever since about 6 months after I got my truck it does this weird thing at WOT going from like 2nd to 3rd gear. It won't always do it though. But it'll get up all the way to 5200 rpms and then hesitates to shift into the next gear for like 3 or 4 seconds and while it's hesitating the engine just keeps hitting the rev limiter and it sounds really odd. I'm not getting any codes or any other shifting problems, just WOT from 2nd to 3rd. I try not to run it at WOT anymore just because it's a little embarrassing driving around and my damn truck doesn't wanna shift. Any help is greatly appreciated.
