I cant downshift my gforce without it grinding badly. Ive tried double clutching and letting the rpms go down, reving it up and nothing lets it downshift without grinding and clunking. I dont drive my car anywhere close to the amount i drove it before the gforce. Heck it even grinds a bit going into gear and clunks without grinding if i get lucky. Its complete butter when its on the floor but thats the only time. Just telling you how mine is. Maybe yours will be better. I feel like it could break at any time when i down shift. I go into a corner in 4th then slow way down to about 15mph and then slam it into second. Luckily the 4.56 gears helps a little on slow speed driving.
