Transmission problem

Every time i park my car in the hillside(like a 35 dagree),i encounter that my automatic transmission will has a little impact betweem gears if you know what i mean. i know that’s normal for the cars when you park in hillside,just wondering is it good for the transmission if i park frequently on the hillside?

That little thing you likely call an emergency brake is really the parking brake. It should be firmly applied before putting your transmission into park. In a few cases it may not be functioning properly. If it is working properly and you are applying it with sufficient force, it should hold your car steadily on that grade.

While it is possible you have another cause, this is by far the most common reason for your problem.
