Well its that time everyone to join. 2 years of good reading here .. thanks to all !I bought a brand new 2015 LT with Appearance Pkg and 1.4L T & 6 Spd Man. Apart from the front grill design, I love the appearance. Its my daily commuter to work, and I was after great gas mileage, good handling, and a hatchback in a GM product.
Now I'm at 46,000 miles, and want to change my Manual trans fluid to AMSOIL Man. Synchro 5W-30. I'm getting conflicting reviews on qty. of fluid, don't we just have to fill it till it reaches the vent opening ? Will this VOID warranty if I don't use GM fluid ? Thanks everyone, and looking forward to many upcoming posts and feedback ! TJW

It only holds roughly 1.5L, 2 bottles will be sufficient. When you collect the old stuff it'll give you an idea on what to put back in.
I'd be sticking with the gm fluid while it's under warranty so that you don't get stuck with a bill for a replacement transmission if it grenades for any reason.
The transmissions in these cars are not serviceable, they're replaced as a assembly
