Should I change Trans fluid? Is it ok?

[feysul]

My car drives ok but sometimes i notice the trans gets stuck in a gear. In particular when I accelerate hard and let go. A gear stays in position vs going down one. Im sorry if i am not using the right terminology please educate me. In general my car runs fine. But i have noticed the trans acting up at times. FYI my car has 107000 Miles. and in good condition

I talked to the dealer and they said that they will not change out the trans fluid. then i talk to other owners and they say that they do.

Just wanted to reach out to this community and see what other owners have done and what they recommend. thanks
