It's random, I don't wanna shift into OD is happening more often. It's fine in 1-3 and then when you go to get on it, randomly it just wont go above 2500-3000 rpm.
It did it to me on the way home from work so after I got out of traffic I turned down a country road and had it up to 40ish and laid into it and it didn't want to shift. So I let off the gas and slowed it down and did it again and it was fine. Then it wouldn't do it again after that.
It's very random and a PITA. No codes, fluid looks fine and level is good. No engine studder, just feels like the transmission is like, mehhh....I don't really feel like it right now, give me a bit. No odd noises that I have noticed. I don't feel the transmission slip at all. Just a hesitation I guess is how I would describe it.
I added a bottle of Lucas about a month ago when we first noticed it and it didn't seem to change anything.
I did a pan drop/filter change last summer, so around 115k miles I think? And nothing looked abnormal then.
