The problem with oil extractors on manual transmissions is the tube can't make it past all the gears to get to the bottom.
On automatics, the extractor is only good for getting the fluid out past the pan parting line so when you remove the pan, you don't have fluid spilling all over the place. Because of the way the tranny pan is shaped, the tube will not get all the fluid out.
They work with engine oil changes because the tube will easily go to the bottom of the oil pan. I pulled the plug after my first use of the extractor on my engine. Not even a drop more came out.
