Hello,

According to the link:

Fitment Details: This transmission is a direct replacement for 1989-1996 Corvettes (excluding ZR-1).

I don't know enough about these to say one way or another but the seller says the ZR-1 is excluded.

I'm definitely no expert on these, but I thought there were a few mods that could be done and the trans would work in a Z?

[jmglyder]

I would hope that would be the case and if so someone will have a brand new trans

There are two issues to understand about the ZF transmission in C4's.


1. The Non-ZR-1 transmission has a shorter input shaft and housing. The input shaft and housing from a donor ZR-1 version can be installed to make the transmission fit in a ZR-1.


2. The later model ZF transmissions have a small diameter input shaft housing and the Throw-out Bearing has internal nylon strips that slide on the input housing. To use the later model transmission on a early model ZR-1, the correct throw-out bearing must be installed. I think that the change occurred in 1994 but you should verify the fit of the throw out bearing on the housing before installing the clutch. I learned this the hard way during a clutch swap job when the transmission could not be installed.

A few more details of the use of a Black Label Transmission in a Later Model ZR-1 (1995 for example)




Blue Label Removed (TOP), Rebuilt (ZFdoc) Black Label Installed (BOTTOM).

Rebuilt Black Label Transmission Installed

It’s a last version Blue label 1052 000 089 for LT1/LT4.

Here’s another new one closer to home but also an LT1/LT4 version.

For the money, to buy one and convert the input shaft, I might as well just send mine to Bill B and have him rebuild it.

Your last option is a winner as Bill B like Marc Haibeck are Rock Solid Professionals and perfectionists in what they do
