I have a 1997 Camry V6 automatic with just over 60,000 miles. The transmission fluid was changed 5,000 miles ago. It is very hard to move the shifter from Park to Reverse, Neutral or any of the drive gears. When I do move it, there isn't the usual click as it is moved from one range to another - you have to look at what gear you are selecting. While in drive, it will sometimes move to neutral on its own. Any suggestions?
