I just bought an 2007 Acadia, knowingly having some shifting issues. It's at 160000 miles. When I drive it it does not sound or feel harsh. It will get stuck going into first or second gear. I have to turn the car off and back on for it to shift. Sometimes I have to restart it twice. When having trouble shifting gears it does not sound harsh on the vehicle but sometimes slightly jolts but then again I just bought the vehicle and it may have been my sensitivity to the pedal especially when getting tons of anxiety looking at the RPM go up LOL.

When I had the fluid checked they said that they couldn't tell very well so I think I need to have it running longer before I check it again but when I got under the car there was a crazy amount of caked up oil all under the car. and when I check the oil it was also low although I'm not sure if that has anything to do with the shifting but that is also a thing. I don't know much about vehicles except through trial and error and I no the right and wrong sounds a vehicle should make. I need someone with patients that can guide me under there too see what may be wrong.

I don't understand a lot of the terms but if dumbed down and explained a description and it's function I can understand and visualize what that part needs to be doing. So literally a description. From the least expensive and easier access timeline of actions to take to figure out the problem. And possibly a series of things needed to check before I put in a ton of money that's not serious or the initial problem creating further damage. I have a set of codes given by the seller, I looked some up and here are my sloppy notes, disregard my personal noting
