'91 L98 manual gearbox, compatible with ZR-1's?

[EuroPete]

Hi guys,

Sorry if I'm asking a dumb question (I made a search and I found nothing in other threads) but here it is: I came across a ZF 6-speed transmission off of a '91 L98 Vette, is it compatible with my '90 Z? I heard the housings are different but, in case of failure of my present gearbox, could I interchange the housings?

I could get this extra gearbox at a very good price so I'm thinking about keeping it as a replacement part for the future.

Thanks a lot.

the input shaft and the collar that protrude form the front of the trans are different but interchangeable in the trans

So I could make a useful trans for the Z taking some parts of it, right?

1990-1991 should have same internal parts.

Post the trans numbers on the side tag of both transmissions the one in your Z and the L98 trans.

Also the color of tags.

I'll collect that information on the tags as soon as possible and I'll post it here.

Thanks a lot Jeff and Pete.

Hi Pete.

Your '91 L98 transmission is the same as the ZR-1 except for the input shaft.

But you nearly neeed to completely dissasemble the transmission to change the input shaft for a ZR-1 one, that is longer.

Next time we met, I will explain you....

I think I know where it comes that '91 trans.....

Ram?n, no worries about the trans because we sold it long ago.

Yes, you are right about the origin of the ZF gearbox :mrgreen:
