Cool! Yes, I see them on amazon. They even sell them individually for a few bucks. Now, what size do I need? I'll have to crawl back under there and try to get a measurement on it. Maybe put that wrench back on it and look for how well it fits. Thanks HY!

 

Curious, will a 12 point spline socket work?

 

Maybe..... If you already have them, it's certainly worth a shot.

 

UPDATE (and for purposes of helping others in the future)...

I found an old 12-point, shallow 11/32" socket rolling around a box of "extras" that fit around the square head on that front band adjusting screw like a glove. So if you have the same adjusting screw with a square head on your A518/46RH (perhaps others), this socket will work. I'm assuming it will work for the rear band (inside the oil pan) too but I cannot say I tried it. I also assume an 8-point, 11/32" socket would work too (as suggested by HeyYou). Any points divisible by 4 I would guess. It should be noted that my 11/32" deep well socket did NOT work because it is a 6-point socket. Guessing an 8-point socket uses all points to grip the square (two points per corner) and on a 12-point socket four of the points go along for the ride.

BTW, my 72 in-lb. "guess" on the front band earlier was off a half turn now that I used my torque wrench and noted where it should have been. Not sure how critical being off a half turn is but I don't have to worry about it now.
