1993 Volvo 960 sedan. 2.9L straight 6 “white block”. Aisin-Warner AW30-40LE automatic transmission. Clunks & shakes when going into reverse whether from park or neutral and drive. I asked Scotty on live stream a week or two ago and he said to check motor mounts, transmission mounts, drive shaft/differential (since it’s RWD); if not then it’s probably the transmission itself. I checked the drive shaft and it’s solid and not loose or anything. I haven’t checked the motor mounts in the way Scotty has mentioned in many videos because I am unsure what part of the engine to jack it up from; however, my neighbor who’s worked in the industry for many years said if it’s motor mounts then the motor will noticeably shake at startup, so I started it up as he watched and he doesn’t think it’s motor mounts. So all that’s left to check is the transmission mounts, but I don’t believe Scotty has a video on that.
