Sudden loss of trans fluid

What type of car are we dealing with?
Get it off the ground as high as you can so you can get to it.
Drop drive shaft. Have a plug or heavy duty zip lock bag and duct tape ready to put over tail shaft of tranny or your gona make a mess. Tape over caps at rear of drive shaft. Disconnect battery. Remove starter. Disconnect linkage, neutral switch wire, and kickdown rod, cooler lines from tranny. Unbolt flex plate from convertor and it needs to be drained if it has a plug then slide the convertor backwards into the tranny. Remove dipstick tube. Support the engine at rear of oil pan with jack stand or a jack. Place a block of wood or pad on oil pan first so as not to bang it up. Drop rear tranny cross member support after tranny is supported with jack. It may be necessary to drop engine/tranny assembly a little to get to the bolts on the bellhousing. Watch the oil filter on the engine. It may need to be removed to give you clearance while dropping the assembly. Unbolt tranny from engine block. Should slide back wards.
