It's a good thing I decided to stop in the 10 minute oil change place during lunch today. Ever since reading on here about the differential being a seperate unit on the 3 speed auto, I've been wondering about it. I just bought this car a week ago, and rember the owner speaking about a half shaft being replaced recently. I just knew the mechanic didn't replace the lost fluid.
The oil change place pumped damn near a quart back into it.
Thanks Toyota Nation for talking about this in the past so I could learn about it.
