I half agree with the previous reviews. Of the several upgrades I did from Taliaferro, this was the best one. The shifter pops in and out of gear more quickly and positively. Don't expect more precision though. And the increased vibration is definitely very noticeable at parking lot speeds. Fortunately that goes away as you get out on the road. I did this upgrade because when I first drove my Viggen I thought the shifter was broken, but that's just Saab feel. This upgrade takes the shift action from terrible to merely bad. You have to decide if that's worth the money and vibration.
