Manual transmission guys???
I have a 99 coupe with a 408 ci. making 454 RWHP 457 RWTQ, MN6 with an ECS driveshaft, 3.42 gears, clutch is OZ-700 X-grip with stock hyd. I guess what im wanting to know is.....This is my DD and I have had to replace the Polit bushing/bearing twice, and looks like im going to have to do it again.. Why would I be having this much trouble with the polit bushing/bearing? What do I need to do to keep the car from breaking or what ever to keep it on the road? Im about to get a new Stage V transmission to replace the one I have. I have tried my best to make the car as relibable as possible. Can any one give me some insight, or am I just wishful thinking....
Thanks for any help, Eric

I'm not a transmission expert, but will share a few ideas: I believe both the C5 master and slave cylinders/hydralics were updated since 1999, which could benefit your setup.
Recommend installing a Clutch Bleeder Line so you can easily inspect and change your fluid as needed. Are you running synthetic fluid? Not sure what fluid limitations you have since its a 1999.
Was the Textralia clutch installed properly? Does it feel out of balance while driving? Did you experience this problem before the Textralia was installed? Very unusual to go through two pilot bearings so quickly.

The exact thing I thought of when I read it,,even before I scrolled down! I have not been in one of the new ones yet,,but I'm sure it would be similar. You need to mount a dial indicator at the back of your bell housing and check for any off center runout of the pilot shaft. Don't know what the specs are but I know it's tight! That is the only thing I know of that will destroy them in short order!!

I will check for runout when the new transmission shows up. The clutch was in the car when I bought it. I have inspected it and found no issues with it or the flywheel. But I will be replacing the hyd. when I get it all apart.
Thanks for the tips.
