I wanted to add that I put the RedLine MT90 GL4 lube in the Transmission. At first I was wondering what the big deal is. After a week of driving it back and forth to work. I see what the hoopla is all about. Nice clean shifts, seems to run smoother? not the engine but the drive train. I am waiting for the weather to ease up a bit and I will put the RedLine GL5 in the differentials and the transfer case.
When I pulled the plug on my tranny. Not much of anything on the drain plug. it was a magnetic plug. I had bought 4 magnetic plugs to change them out. I guess I did not need to waste my $$$. Just some fine, powderish sludge on the magnet part of the plug.
