What size is the 550 (M273) pulley bolt?
I'm gathering up what I need to change my tranny fluid, and need a socket to fit the main pulley bolt so I can get to the TC drain plug. In the sticky above it says 36mm for whatever engine that was, but no way mine is that big - more like 26mm - but I can't get anything on it to measure it.
