Is there an aftermaket transmission pan that has a drain plug in it for the 4 gens? Or has anyone ever drilled a hole in the OEM pan to a add a bolt for draining it?

Why would you want to? Changing fluid without changing the filter? You know wiping out the clutch material out of the bottom of the pan and replacing the filter is more important the the actual fluid change?

Don't beat me up for this but, Honda and Toyota have stopped using "filters". Wouldn't it be a good idea to swap the fluid ever 20 and flush with a filter change ever 60? I plan on keeping my Z for awhile.

You change your engine oil for two reasons. One is contanimant aka dirt. Most dirt in the oil comes past the rings with the blow by. Some comes into the engine through the venting system but I would guess 98% is from the blow by. Second is extreme heat, Yes your oil stays around the same temp as the coolant but it is exposed to extreamly hot areas in the engine like the exhaust valves and piston skirt. This breaks down the oil.
Your transmision does not see these conditions. The primary reason for transmision services is to clean the filter and the pan. In fact when you service a transmission you only change about 1/3 of all the fluid in the tranny. If you follow GM guide line and you sell your car after 8 years and 150K some of the trany fluid will be the original factory installed fluid.
If a company stopped using a filter that means they came up with a another way to insure clutch material does not overcome the fluid intake system.
