I don't have too many other needs for a 23mm socket. I ordered 2 when I got it, though -- just in case. I think they were $4 or $5 each from mcmaster-carr. It says in my 'special tools' drawer with my valve adustment tool and other gadgets.

 

I went to Sears and found one...YEAH!!!! I am now finished with the fluid change. Pretty easy. I love how the car feels with fresh oil. I did the engine and tranny. The shifter feels great.

 

craftsman that way if you break it they will replace it free of charge

 

I cut my socket down and it fits perfectly with plenty of room for a torque wrench...
You DO NOT want to over torque this bolt.
