I had issues like grinding into 2nd cold or warm until corvette tech did this and since then, it's been very good. The way I would expect it.There is a shifter alignment procedure (see attachment) that the dealer or you (if you're even moderately handy) can perform that might help with the popping out of gear and difficulty engaging first. Haven't heard anyone else talk about fluid burping. Definitely don't think it's normal. I'd find another dealer to talk to.
