Synchronizers?
In my 97 z/28, it's starting to make a weird noise going from 1st to 2nd. Mechanic father said it's probably the synchros... my question is can I just replace the 1->2 synchros? Or should I replace all, or anything else for that matter?

It is odd that it's making a noise, but it is possible. So to answer your question, I would recommend going through the entire tranny. Of course it would have to be completely disassembled to get to the 1-2 synchro assembly anyway. It is very common for the T56 to have unexpected problems in the works, but no symptoms. It can take a year or longer for a problem to show its face. So in order to do the job right, its best to bite the bullet and freshen the tranny up completely. The Stage 2 build includes all new wear parts, plus the billet 3-4 keys and steel 3-4 shift fork for $680 total. Let me know if I can help or if you have any more questions! Thanks!

Plan on the 1-2 synchro, probably 2nd gear and a general refresh kit (synchro blocker rings, keys, key springs)
When you open it up, you may find 3-4, 5-6 or R to also need parts. That's why I tend not to order parts until it's apart.
Could you just do 1-2? Yes. But while you're in there, you might as well make it like new.

I would love to do the entire tranny, just strapped on cash right now. I also saw the thread about not being able to downshift to 5th from 6th which mine has always done since I swapped it in. Here's a video of the sound. It does it unless I shift really slow, or go to neutral before 2nd. Click for the video.
