You should be luck you only get a shudder..... In our 96 A4q 2.8 slushbox we get a thump at just under 25mph every time you decellerate. Thats without the thumps going from park to drive or drive to reverse......(More to come on this as I aint going quietly on this one....not on a damn 35k motor car!!)
