Great tool for trans and diff plugs
 

Low-profile 24mm socket:

Used this for my 90k maintenance. It's so shallow that I could easily get any kind of socket wrench on any of the fill/drain plugs on the trans and diff. No more fiddling with box wrenches!

FWIW.

You hit the nail on the head. I won't use a wrench on a drain plug unless there is no other option due to clearance issues. Too much of a chance to round the drain plug.

I can't remember how I got at the plugs when I changed trans and diff fluid. Why won't a regular 24mm socket fit?

IIRC, most 24mm sockets would be fine for the trans but the space around the diff is too tight. That's why box wrenches are popular for this job.

Am I missing something? I just use a standard 24mm socket. For the diff, I think I just used a 24mm socket and a short extension to get through the diff carrier.

Pretty sure I've done that, too.

I like the low profile socket better because you can get right on the bolt. It's much less fiddly and there's no chance of weird angles.
