Manual transmissions don't have a dip stick. You have to do the "digital" test...just like a proctologist! 
How to check the fluid level on a manual transmission.
Park on a level spot.
Pull the fill bolt.
Insert finger and test the level. It should be within a 1/4" from the top of the fill hole. If not, top off.
Since yer changing the gear oil in yer transmission...I would highly recommend that you pull the fill bolt first. Seems the person who puts that on fer Toyota is trained to apply gorilla force in putting it on. Once you git that off, you should be able to pull the drain bolt to drain.
