Looking for help with my ZC Trany!!!!
 

Ok well I am about to go on my 5th ZC tranny. I have blown the diff out the back of the last four along with a Si trany. Today when I shifted in to 3rd the car made a huge bang and made the car buck real hard which even threw my rear view mirror off. I thought for sure I blew it up but it did go in to gear and 1 min later I heard and felt another bang. It has also been making a wineing sound when I down shift to stopp for the last couple weeks. Could this have something to do with it going? I am running a ZC twin cam boostin 6lbs. With the other 4 tranys I was using a centerforce dual friction clutch but I just tossed in a stock disc for now until my 6 puck ACT comes. Ok so is anyone else having this problem? If you need any more info feel free to ask. Thanx

I found most tranny problems are related to how hard you beat them up. I know a guy who just kills trannies left and right. When I saw him drive, I knew why. I bet you have the same problem. Try driving more gently, don't beat it, DRIVE it. Either that or get a custom gearbox built for you by gearspeed.com.

also, centerforce clutches and import cars don't mix well.

The wineing sound you were hearing was likely your input shaft bearing. Failure is immenant after it goes.

Thanx guys for the input. I guess I am on the hunt for another 88 ZC Tranny.
