Questions: Fluids and Wiring

I've run a bunch of different oils in the 3G Hemi. I run conventional for at least first 500 miles or so. Straight 30 wt. Then 20-50 amsoil for high temp open road racing. Also have run 5-20 in the past (factory spec for 5.7 if I remember correctly).

I run synchromesh in my tko. I was thinking the t-56 is a different spec? I would recommend sticking with what is spec'ed for your specific t-56. And t-56's have different spec oils due to paper vs carbon (I think).
