hello, so i just bought my truck a few days ago and i am wonder what might be causing this problem. The problem is when i shift out of park it clunks in what ever gear i put it in hard, its not a smooth transition. Also when driving it shifts hard between gears. And when on the high way the truck would vibrate but when it would shift the vibration would go away. what are possible problems that i could be encountering? any input much appreciated. thanks

 

Check the ujoints

 

could it be bad motor mounts or tranny mounts? the u joints feel good

 

Not sure. Have someone standing to the side with your hood open and shift from park to drive. If it's clunking it should visible move.
