Transmission question about Acura TL 2005
 

When I am driving sometimes it feels like it may shift gears or jump a little. I am wondering if anyone else has had this happen and could it be just the gears shifting. ? Also how will you know it’s time to change the timing belt if you do t know the history of the car before 165,000. I can’t afford just to pay a thousand to have the engine taken apart. Thanks.
