We had a service loaner that developed transfer case problems. (dealer told me after it was towed in that the transfer case needed to be replaced).
The car would jolt maybe a foot when put in park. My wife drove like this for a day and a half.
Funny story, since it was a loaner, she put regular gas in it, she thought because she put regular gas it was just running rough. I didnt think anything of it the fist couple times she mentioned it, but then the next evening, she mentioned it again, so I took the keys and backed it out of the driveway and in again. Needless to say I called the dealer and had them send a tow truck.
