Problem accessing differential fill plug on 1996 corolla DX

[tritri]

Can any body give advise here?

I have a corolla 96 DX, 3 speed automatic. I just changed the ATF today, it is very easy. But I have problem to loose the differential fill plug. There is very limited space, and I couldn't apply enough torgue to loose it;

Does any one have idea how to deal with this? Is there any special tools. It was blocked by chais, so I can only move the wrench 10 degrees a time.

use an impact gun with a long extension

Use one of those flat ratcheting wrenches. It should be an 18mm and you can buy them individually at Sears, or an entire set for $39 right now on sale for Christmas.
