I went from worn original motor mounts to BDE OE-style motor mounts, couldn't recommend them enough. I'm convinced they made a huge difference with how smooth the transmission shifts. I had a ZSpeed shifter bracket installed before this change, which may have amplified the sensation. Several people who have driven my car cannot believe the trans has 230k+ on it, and I'm certain the motor mounts are a large part of it. I'm very curious to try the BDE trans mount someday once my OEM goes.
