I have access to the Auto Skills Shop on the local military base. It's staffed by DIY-ers with grease and oil permanently embedded under their fingernails! They are familiar with the transfer method of fluid change. I know there's pictures on the forum of how-to, so I won't be *completely* lost.
Looking at the PDF of the transmission and cooler - would it be better to come off the xmsn cooler outlet tube to flush out the cooler too?
