I’ve got the same issue, does it on 3rd and 5th. I’ve driven it like that over 20k miles and it hasn’t broke down yet. The only way to find out exactly what’s wrong is for them to drop the transmission and pretty much rebuild it. I’ve had a couple of mechanics look at it and drive it around and they said the only way to find out is to drop it

I don't think they rebuild the trannys, they just replace them. Thought I read where even indy tranny shops can't get a rebuild kit for them. Maybe that was for the newer tranny models.

I have NEVER heard of any one on this forum getting a transmission rebuilt. There is no data/parts available to do a rebuild. Best bet it to take to dealer and do a relearn and maybe have the fluid/filter changed. Otherwise a new/used transmission is likely needed. I had a similar issue, relearn procedure did not fix it, had a used low mileage transmission installed Mine is a 2011 4.6 and had around 95,000 at the time.

Curious if anyone having this issue got their tranny fluid replaced at some point in the past. I bought a new one, trying to plan.
