What did I break in the trans?? car no move
So I was about to party, then the party stopped with audible snap
no leaks, both rear wheels turn when I jack it up, what shaft should I expect to be broken when I disassembly?

You still on the T56 and C5 diff?

If you hear gear lash/wine with the car jacked up and spinning either wheel, youve lost the trans output shaft more than likely

That's what I was thinking, trans shift, wheels turn normal by hand, but I have all neutrals. Ordered a gforce main shaft, I'll disassemble over the weekend. Rematch rescheduled
Yes, Stockish stuff, I have hardened output in the diff.

I'll adapt if the situation is worst when I open it up.

I went thru two main shafts on last z06. Stock 27 and a 30spline.
Did you have the cage around the trans and diff? Also what diff mount do you run?
Replace with a 30, send your pinion to marc@gforce to match the 3spline. Run a cage and a pafdt diff mount, make sure everything is setup good. Just my opinion.
I've got a c6z drivetrain now on my new car, just need to learn how to slip and launch the car when I start tracking again.
Good luck.

Thats exactly what broke on mine last spring. Rolled out in 1st and got to about 35-40mph as the nitrous was ramping and was about to grab 2nd and all of the sudden had 6 neutrals lol. It was a pretty clean break like that too. I sent it in to RPM since the trans was a little tired anyways so it got a few new gears and sychros, 30 spline mainshaft, and machined the diff to accept the 30. I then added an ECS brace. Haven't really dug the car much since but its been holding up great from low rolls.

Wild imo, that you broke with both supports but you do make power and was the stock 27spline.
G-force makes a 30 Spline 9310 Alloy Mainshaft. Only like $150 more than a stock gm 30spline for the 97-07 t56.
Mark Shifflett mark@gforcetransmissions.com is awesome to work with. Sent him two diff pinion gears to machine the pinion gear to accept the 30spline. I'd put money on no one will compete with his prices.
A t56 with 9310 30spline is top of the line!!!
