2008 Jeep Grand Cherokee Shifting

SOURCE: noisy shifting

I'm wondering if what you are hearing is the driveshaft universal joints. If they are worn they will 'clunk' every time you put the vehicle in gear. Block all wheels to check, put vehicle in neutral, NOT running, crawl under and move the driveshaft back and forth while watching the front then rear u-joint. It should be obvious if there is 'slop' or 'play' in them, which would indicate they need to be replaced.

Check the Trans fluid level with it running and at operating temperature. Jeep NAG1 transmissions are known to have the input electric seal leak trans fluid. Not an exspensive fix add Mopar ATF4 and then relace the guild seal.

Likely the shift detent mechanism is broken. It's inside the unit and can be reached by removing the trans pan. It should be just inside where the shift lever goes through the case.

I would check the transmission fluid level and color, should be a nice clear red color. You may need to have the filter replaced. Possibly some internal transmission problem also.

They way you replaced fluid is bad, you should of done a bg service, by dropping the pan theres still oldoil ,the converter is full and the lines and the cooler and inside trany, then when new fluid is added the cleaners in it loosen all the dirt and seend it through the trany, the bg flushes 100% of the old fluid so no mixing of old contiminated and new oil is taking place.
