Looking at a 2004 Grand Prix GT1 with 56,000 miles that has a faint popping feel (like a tiny bump) when put into reverse and then again when put back into drive. Was told that it needs an engine/transmission mount. Plus, the speedometer spins wildly at a moment's notice. (Mostly after a right turn.)
Are the two things related? Does either suggest that the transmission has been removed or otherwise had work done on it?
