OK, My bad guys!
I have run Redline syn in my T56 & Diff since 04 with never an issue.
The box is Camaro but now fitted with Gears for a Holden VX as it got rebuilt in 04.
My diff is a Salisbury, 28 spline axles, Limited slip. Nothing fancy but has handled my occasional road racing & Drags all the while using synthetic.
Engine uses Valvoline Syn 5w40.

the diff takes 75w90 oil and i believe calls for synthetic from the factory but again thats not absolutley necessary. is your car a 98 or 99-up? if its a 98 you have the auburn posi unit and you also need to add the friction modifier to the oil for the posi whereas 99-up got the torsen and that just takes the regular oil with nothing else
