Castrol trans fluid, gear oil for the final drive:
I had a gear oil bottle with a little left from a previous fluid change. I also got a piece of tubing to make filling the final drive easier.
Draining the final drive:
Draining the trans and final drive:
Pesky dipstick tube:
Old O ring, new Otterstat seal
Installed:
