OD off doesn’t stop it. As best I can tell it’s like it’s pushed up to the point to shift in the final gear but just can’t quit decide to. If you ease off the gas or speed picks up slightly it will shift on and it stops in the next gear. Same if you apply a little more throttle and go deeper into that gear. (Not so much you downshift)

I'm a little late to the party but curious if anyone figured this issue out for sure. I have a 2007 SEL Plus that I acquired, I recently replaced the engine (old one was at 235k, new one has 82k miles) it does the exact same think before with the old engine and now with the new. Coil packs and throttle body are different with the engines. It has that 100 rpm surge at about 1500 rpm and seems to be specific to the high gear.
