% of HP lost through the T-case

[PUR PONY]

Does anyone know what % of HP is lost through a Transfer case? better yet the AWD t-case?

If I remember correctly isnt it 20% hp lose through an automatic transmission??

Some trannys use more HP and some less. I'd guess that an Explorer tranny uses 10-15% Hp and the transfer case is about 1-2% I'm no engineer so take this for what it is worth.
