Your ZF6 makes noises or won't shift, what to do?

[tomtom72]

I'd just like to thank you for adding your knowledge to this transmission thread!

As an aside, I would beg your indulgence if I might ask a few questions of interest to me a 90 Z owner about the speed sensor.

Is that the part that is often referred to as a VSS in the Helm manual?

The 90 VSS is a 90 only part, right?

And it's NLA from GM?

Do you think that your source could get any more?

Sorry for all the Q's.
TIA

Tom
