That should be the crankcase breather tube.
Your transmission does use lube oil. It takes a thicker oil like 75w90 or 90w140 and NOT automatic transmission fluid.
2 1/2 to 3 quarts
The 1974 VW Super Beetle engine oil capacity is 3.5 quarts. Three quarts of oil will be in the engine and one half quart of oil will be in the oil filter.
A 1974 Volkswagen Super Beetle typically holds about 2.5 quarts (approximately 2.4 liters) of oil when using an oil filter. If you are including the oil filter change, it may require around 3 quarts (2.8 liters). Always consult the owner's manual for specific recommendations for your vehicle.
I have a 73 Super Beetle restored with a 1600 engine. Two questions. What is the best grade of Gasoline to use? Can you use Mobile One Oil? Thanks. Perry
