vibration
Hey Guys, I have this vibration @ idle that vibrates the whole car, not so bad at about 1050 RPM, when put into drive (yes it is an automatic) and the rpm drops to about 900RPM it really gets worse. I just replaced belts making sure that balance shaft rollers were on there marks. I also replaced the motor mounts upgrading to turbo mounts, all with no improvement. Anyone have any suggestions?

it sounds to me like its a transmission issue. If it only happens once you put the car in drive, and not when the car is idling in park, and the revs drop when you put the car in gear, that says to me that the torque converter isn't doing its job correctly and the engine is getting loaded somehow (and my engine at least doesn't much like running below 8-900 RPM, causing some vibration)
