It sounds like the transmission is slipping.

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.
