Joe Gibbs , Brad Penn & Driven  have high zinc motor oil & special oils for break in .
Manual trans / 833 use a GL4 oil , anything GL5 is too slippery for the syncros to work properly .
Diff I use 80-90 gear oil with additive for sure grip , I have heard of problems using synthetic oils but I have never actually witnessed a problem
