Default Re: ZF Transmission stopped working

This '90 is being parted out. You should inquire about the transmission.

Or try and track down this wreck and see if the transmission is available.

Good luck!

I would like to know what a good used ZF6 black tag transmission is worth as I have one from a 17,000 mile wrecked 91 Z.

$2k and up is a good starting point from what I have seen online.

Yeah, got here last fall. Just having a hard time getting started on a garage shop, everyone is too busy I guess.

I did call him and he didn't have anything but he told me about a guy that he used for his transmission and never had any problem with them. I'm currently researching options. I do have the car setup for the transmission removal on the 31st. Just need to see what options present themselves.

Roy, I know I am late to the discussion, but Bill Boudreau built the transmission for my car and he was great to deal with. My local Chevrolet Dealership removed the transmission, installed the new one built by Bill and crated up the old one and returned it to Bill. The dealership even installed the new Clutch and Pressure Plate recommended by Marc Haibeck, which included some shims.

I know, Joe. The problem is that Bill doesn't have any built up. I did talk to Aaron Scott and he didn't have anything but recommended a guy in Tallahassee that has some ZF's there. If he can do it, I intend to buy his transmission and have it installed at the same time as they pull the other one and ship it to him. If not, My car sits for a little while while he rebuilds mine.


Either way, it will take some time.

Default Re: ZF Transmission stopped working

I had the transmission pulled today and they found out it's not the transmission, its the clutch. The owner of the shop checked out the transmission and said that it's good. Apparently, the rear mail seal blew along with a ball bearing coming out. I will have to have a new clutch and a new flywheel. Some other issues occurred during the failure but I don't have any details. One thing I do need to find is the duel mass flywheel. GM shows that that they are available but the guy is having a hard time finding them.If any one has any leads, please let me know.

I sure would like to hear more about that when you know. "Blowing" a rear main seal? "Ball Bearing coming out??" Wow!!

You should get some photos if you can.

Sounds to me like the throw-out bearing may have let go.
How many miles does the DM flywheel have on it?
