Cayenne 2004 S
 

Hello Porsche friends, I need a little help? I have a 1999 boxster and it is excellent. Just bought a 2004 cayenne s, has 82000 mi. I am getting a hard "clunk" when shifting under acceleration? Have done some research and seems it's the manual valve body? Are insight? Trans control module? Triptronic issue? Also my dash display is showing D instead of gears 1-6? Any insight would be greatly appreciated. Thank you
