You DO NOT have one.

There is a small bolt/plug in the transmission above the pan that needs to be removed. The fluid will run out if it's overfilled. The transmission needs to be at room temperature or a little warmer to check the level.


The fluid level screw is intended to be used for diagnosing a transaxle fluid leak or resetting the transaxle fluid level after service that involves a loss of fluid.
Inspect:
The fluid level should be checked when the transaxle is near Room temperature or at 40°C (104°F).
CAUTION: Removal of the fluid level screw when the transaxle fluid is hot may cause injury. Use care to avoid contact of transaxle fluid to exhaust pipe.
The engine must be running when the transaxle fluid level screw is removed, or excessive fluid loss will occur. Since the actual fluid level is unknown, stand clear when removing the fluid level screw. Have a container ready to capture any lost fluid.
WARNING: Do not turn the engine off with the fluid level screw removed as you can be injured by hot transaxle fluid being expelled out of the fluid check hole.

1. Let vehicle idle for three to five minutes with accessories off.
2. Apply brake
3. Move shift lever through all gear ranges, pausing three seconds in each range.
4. Place shift lever in Park. Important: Vehicle must be kept level on the hoist.
5. Raise vehicle on hoist.
6. Place oil container under fluid level screw.
7. Remove the fluid level screw with the engine running at idle.
8. Fluid level should be at the bottom of the fluid check hole. Because the transaxle operates correctly over a range of fluid levels, fluid may or may not drain out of the fluid check hole when the fluid level screw is removed. If fluid drains through the fluid check hole, this transaxle may have been overfilled. When fluid stops draining, the fluid level is correct and the fluid level screw may be installed. If fluid does not drain through the fluid check hole, the transaxle fluid level may be low. Proceed to ADDING TRANSAXLE FLUID.
9. Install fluid level screw. Tighten 12 N.m (106 lb in)
10. Lower vehicle.
11. Shut off engine.

Adding Transaxle Fluid:

1. With the engine running, add fluid at the vent cap location in half liter (1 pint) increments until fluid drains through the fluid check hole. Allow the fluid to finish draining through the fluid check hole.
2. Install fluid level screw. Tighten 12 N.m (106 lb in)
3. Lower vehicle

You have what is called a closed cased transmission. You have to crawl underneathe to get to the tranny and remove the upper bolt close to the side of the case (more towards the bottom of the transmission). When you fill it, you fill it till it starts to drip out of that hole.

Looking for a picture for you.

SOURCE: Trans-axle fluid leak

checking the transmission fluid involves lifting the vehicle and removing a plug on the transmission, it is quite difficult and messy if you don't have access to a lift, the vehicle has to be level and at operating temperature in park, there is a small plug on the side of the transmission near the passenger axle shaft. remove the plug slowly, i believe it is an 11mm bolt, if fluid drips out, the level is ok, if no fluid comes out, there is a small plastic screw on cap on top of the transmission itself on the driverside near the oil filter cap, add fluid slowly untill fluid starts to drip out of the plug hole, once the fluid starts to drip, insert the plug and tighten, don't overtighten, just snug it up.!!!make sure you use the right fluid, this is important!!! i believe your fluid is dextron 6, double check in your owners manual, the use of any other fluid will cause damage!!! also, do not remove the small plug on the front of the transmission, that is the pressure plug, all the fluid will shoot out with force if that plug is removed!!!

It has a plug in the end of the case by the passenger side cv shaft. Start the engine and remove the plug. Fill the trans thru the fill cap until oil runs from the hole. Let me know if you need more info. The transmission is a 4T40E Right? 4 speed?
