tapping M8 TC
I just got a new remanufactured Mark VIII TC, which does not come with a drain plug. Was wondering if I could tap a hole to fit the drain plug from my old '95 TC. Anyone done that before? Any risks of screwing up the TC? What size hole should I tap out and where is the best place to put the plug? I've never tapped out a hole before, but I have access to tools. Or should I forget about the plug, install as is, and use the cooler-line method (by the way, when draining using the cooler-line method, is there any risk to the tranny when all the fluid is flushed out with the engine still running?).
Also, I need some advice on what kind of transmission jack I should get to install the TC. I'm going to be using jack stands and the "unbolting-pumpkin" method, so I won't be needing to remove the tranny (just need to be able to slide it back to access the TC). Should I just get an adapter for my hydraulic jack? Or is that not a good idea? Thanks in advance.
