It was easy swap out like 20 minutes total I did was one by one. Felt firm big difference.
Like everyone else has been saying on the reviews, this item takes away the sloppy/mushy shifting especially 2nd Gear Grind, this is notorious for during fast shifting. Paired with the bushing this is almost complete. Just need the transmission upper/lower mounts but hesitant on the addition vibration. *Note* when trying to remove the rubber housing, and assuming you have all bolts out. Lift up the entire shifting harness assembly and push downward on the rubber housing, this works better vs trying to needle nose then pulling upwards.
Improves shifting accuracy
The product does as advertised, I would of given more than 3 stars but the instruction supplied was for a Cobalt and not for a Sonic and the bushings were really hard to install since they were a bit bigger than the holes at the base of the shifter unit.
See my review on the cable-clamp. Installed them together with some new transmission fluid and it's nice. Really, really nice.
Sonic shifter Bushings
Oder arrived a few days early. Super easy install, shifting is way better now. Easier to find gears, feels solid. Awesome product.
