HELP! Ready to give up!
HELP! Ready to give up! I have a 98 Z28 M6. Nothing but tranny problems since day 1. It would shift fine but under a high load it would grind if I tried to push it in to gear. Put synchro oil in the tranny and helped with everyday shifting but not under any kind of load. Put new centerforce dual friction clutch, release bearing, pilot bearing, fidanza aluminum flywheel, and pro 5.0 shifter. Drove fine and shifted fine for 1 week. Then hydraulics failed. Replaced master and slave cylinder. Now shifts fine but still wont let me shift under a high load. Dosent grind but just wont go into gear for a second or two. Do I need a new or rebuilt tranny, or clutch or hydraulic problems. Thanks for any help.
How did your hydraulics fail? Slave cylinder get cracked/beat up by the input shaft?
Poor shifting under load could also be a drivetrain alignment problem. Especially if it's happening in all gears and under high load. How are your engine mounts, bellhousing, tranny mount and torque arm mount? Do you see the trans shifter move alot under hard acceleration?

If it's a hard shifting problem in all gears then yes. Especially with a situation where there's been failed hydraulics. You'd have to be an idiot to blow out all the synchros or bend all shift forks in the trans. Here's the official GM troubleshooting chart... Notice they don't go ripping transmissions apart until they check everything around them.
