Yea uh last may I rear-end a minivan. I was only going about 10mph. But it fast enough to cause the engine and transmission to shift forward. Then part of the gear shifter mount came out of its holder, its got a long rod that reaches back past the shifter a little ways to a holder that gives the shifter support. So then the shifter was bouncing on the driveline. Best replace the rubber mounts.
I havent replace my motor mounts or tranny mounts yet, been focusing on a motorcycle, but I will sometime this year. Probably take no more then an hour to both sets of engine and tranny mounts. These cars have some of the simplist motor mount design I have seen, so easy to replace. Later
