I want to get my transfer case fluid changed & I know from your videos that with an Auto transmission you say not to go to a Quick Change Oil & Lube place because they just push new in & pull out old fluid which can get dirt deposits in the very small spaces of the tranny.  You should drop the pan & change fluid along with cleaning the screen I assume.  My question is does this also apply to manual transfer cases or is alright to have them change your fluid, in what I am assuming is the same push/pull fashion that they do with auto transmissions.  My vehicle has 90,000 miles & I am starting to change these drive train fluids that don't get done much.  Thanx!!
