[WVZR-1]

You won't find reference to it. I don't believe there's a necessity for it unless there was something done foolishly internally of the transmission that would have eliminated the drive/driven combination for the VSS. All C4 Corvette 700R4, 4L60 and 4L60E tailshaft housings I'm quite sure are the same for the one piece case that was used. I would have thought unless the controller wanted to see a different type of signal it could have been assembled with a 15 tooth drive gear and maybe a 41/42 tooth driven using your VSS from the ZF. The 15 tooth drive is a tough find but I believe I could. The source might be very expensive. Very!

It could be done with a 17 and a 45 but the speedometer would read a little fast. 45 is the MAX driven available.

I believe that the 4L60E uses a relluctor wheel and a different VSS originally but I would have guessed that it could have been accommodated in the transmission build. It may very well not have been able to have been done because the output shaft is differently part numbered, maybe my thoughts are all wet but I've seen extensions made for the 2-piece case 4L60E that offer up the drive/driven VSS combination needed. I had found information that mentions the internals remained interchangeable.

I actually thought maybe the build would have been done with a 2-piece case since there's a QuickTime housing that mates the LT5 directly to the center case and there's a 6 to 4 bolt adapter and extension to finish it off. I did it on paper but wasn't able to confirm one dimension which would have confirmed the build was a dimensional fit correct for the C-beam and the drive-shaft. It's generally mentioned that any 4L60E can be fitted to the C4 using a cut-off wheel to shorten the output-shaft by 1".
