In the transmission. You pour in fluid the same place you check it. It goes out the leak. Presumably onto the ground. My 1992 and 93 Metro manual transmissions have a refill plug an inch or two aft of the drive-shaft to the driver's left front wheel. My 93 refill plug has a three eights square recess to insert a regular extension rod (NOT the type used for 1/4 or 1/2 inch drive sockets). The Transmission Fluid DRAIN plug on both the 92 and 93 has the same type 3/8ths square recess, to loosen or tighten it. The 92 refill plug has a head that can be turned with a 15/16ths socket (about 23mm, in metric). On the top of the transmission case, above the driver's side drive-shaft, some OTHER metro manual transmissions, INSTEAD have a screw-in, lawnmower/motorcycle type, dipstick/oil level check plug (these have a flat extension to loosen or tighten the plug "with your fingers"). To fill, just add 80 or 90 weight gear oil, screw and unscrew the plug to check the level on the dipstick, and repeat as necessary. On my 92 and 93 metros, I use a "turkey baster" syringe-type oil transfer pump. (A funnel, connected to a foot or so of small tubing might also work.) After about two and a half quarts of 80 or 90 weight oil is put in, it starts to flow back out of the filler hole, and it's full... without having to constantly check a dipstick. (The proper oil level is "even with the bottom of the filler plug hole".)
Remove the transmission dipstick and insert a funnel into the metal tube. Be careful you don't over fill though.
Just go to autoparts and ask them.They have gear oil for manual transmissions
Have you fixed this yet? The fix is cheap and easy. Let me know if you haven't yet. Mr Geo Metro leehduncan@verizon.net
It is important to maintain the fluids in a car. Looking under the hood, there is a large yellow knob labeled power steering fluid only, this is where the fluid goes.
so go to the parts store and get them
The fluid could be too low to allow the transmission to shift. Depending on where the fluid leak is, the leak could be through a bad solenoid or soaking electrical connections, stopping the transmission from shifting.
You shouldn't be able to overheat a Geo Metro unless there is something wrong.
It depends on the size of your engine.

It should. To better check, go to local parts store and check the Haines Manual...is should be for both Geo Metro and Geo Storm, just check that is bolts up the same.
Near the back of the engine in the middle there is a dipsick. Take out the dipstick and put a funnel in there and fill it up with about 4-5 quarts of oil if your changing the fluid. Use dexronIII fluid.
Because one quart of transmission fluid isn't enough. Call a Chevy dealership and ask them how much more you need to put in.
