Drain 6-speed trans and bevel box
Do I drain the trans and then the bevel box but only need to fill both through the trans?
Will use Redline MT-90. Any other suggestions for additives? It has 150K on it.

Note, Replace the fill/inspection plug/locking bolt with a new part. Don't cheap out and reuse your old one.
