Hi, a new user here to the forum. My father just purchased a used 2017 Rubicon DCT (~3,000 miles) from the hills of West Virginia. The four-wheeler needs some love as the original owner liked to take it mudding and used it to bulldoze trees down in the forest (plastic and front bumper are all messed up). The problem we are having is with the transmission shifting, when shifting between reverse and neutral or neutral and drive it shifts very hard, lurching the biking in the process. Occasionally it can't make the shift at all and you will hear the shift motor trying over and over again to get into gear. Also while going through the gears its very sluggish, but from what I have read on the forum that may be normal. Any help or advice on this predicament I'm in would be greatly appreciated.
