I have looked for the stuff everywhere and nobody sells it in anything larger than a quart from what I have seen and the only brand I have found so far is Valvoline. I like valvoline and actually run their oil in my engine, but I just find it kinda strange that it's the only thing anyone carries.

 

Try a dealership, or a real auto parts store like NAPA if you've got 'em on the west coast.

 

Haven't looked at a dealership yet, but I have been to Napa, Kragen, Oreilley, Walmart, Target and the only thing anyone has is single quart valvoline.

 

Why not order it from AMSOIL? Your transmission will shift far better than using standard petroleum based fluids, especially in cold weather. The T3650 5 speed in my 2008 GT and the T6060 in my 2009 GT500 both has improved shifting in hot and cold weather after the swap. I will NEVER put a dino petroleum fluid in my manual gear boxes again. Unless you prefer a notchy shifter, I recommend you do the same.
