I am fixing to buy a z06 clutch kit, clutch master cylinder, and clutch slave cylinder from gmpartsdirect.com but on there website it says all of these are for z06 with mm6 transmission. i have a 99 z28 with t56 transmission i was wondering if these products i am wanting to buy will fit my tranny. so if anyone can tell me if these 2 trannys are the same tranny i would highly appreciate it. thanx 99zrocket

The 2002 f-body cars also received the steel shift forks, and carbon fiber blocker rings. And if you have had you 2001 or older model cars tranny rebuilt lately by the dealer they now install these upgraded parts. I haven't trashed mine lately but I've trashed my clutch.
