Hi, I'm Ron and I will be helping you today.
Stand by for a moment while I prepare your answer.

This does sound like a trans issue.

Here’s the sequence of events I follow:
Check fluid level and color. Make appropriate repairs.
Check shift solenoids with a scan tool in bidirectional mode if
applicable. Shift solenoids are inside the transmission and this is
the easiest way to check them.
Drop pan and inspect for excessive metal shavings inside pan.
Check valve body and clutches visually.
Hopefully you may not have to go this far, maybe you just were a
bit low on fluid.
Thanks, Ron

Our goal here is to assist you in the repair of your vehicle by
supplying you with well educated information. We may not always
have the exact fix you wanted to hear, but our job is to get you on
the right track, which we always do. We can’t hear, see, smell or
touch your vehicle from where we’re at, so your understanding of
that is greatly appreciated. There are no magical or miraculous
answers, but we do our best to guide you in the right direction.
Thanks, Ron
