Toyota Repair: transmission fluid, manual transmission fluid, cv joints

Question
I just replaced the cv joints and the manual transmission fluid leaked out. How do you add it and how do you know when it is full. I cant find a dipstick  anywhere. It is a 1992 toyota corolla dx 5 speed.

Answer
There is no dipstick on a manual transmission.
Remove the plastic cover under the right side below the radiator, the transmission fill plug is on the side of the transmission, I believe it is 17mm in size, add gear oil into the fll plug until it starts to run out of the opening, then it's full.
