trans mount giving me hell! ok so i wasnt happy with the play i was getting in the shifter under heavy acceleration so i bought a prothane trans mount. now i have the worst vibrations through the whole car. it feels like i am running on 6 cyl's. anyone know what could be wrong? i am not getting any ses codes. the trans feels real solid, but the rest feels like garbage! HELP please. i had somebody at a local shop do the install for me. i am going to check it out tonight. any insight would be great.

poly trans mounts are just terrible. The movement in the shifter is mostly from your torque arm (which is a long arm that connects the rear axle to the transmission). Go back to rubber and if the play in the shifter really bothers you, get poly motor mounts (which have no draw backs, unlike the trans mount) and get a torque arm setup that doesnt bolt to the transmission.

i inspected the motor mounts and the driver side show a small and what i would call a medium split in the rubber. if i go to poly motor mounts do they also cause similar vibration? anyone running poly motor monts and trans mount? or is poly motor mounts and the regular rubber trans mount a better street setup?

Grind off the preload bumps. Helps alot. May want to take out the spacer plate too... some times it causes a slight mis-alignment in the drivetrain causing a vibration.
