Hi losflip,
There is a plug located where the right side axle shaft enters the transmission it is above the pan. To check the fluid level of the transmission the engine must be at operating temp and the vehicle must be level. The must be running and the transmission in park, the plug is then removed and if transmission fluid starts dripping/leaking out it is full. If not transmission fluid should be added till fluid starts leaking from the plug hole, then just reinsert the plug and tighten. Generally this is done with the vehicle on a lift in order to access the plug, you might be able to do this if you have enough room to access the plug remember the vehicle must be level.

Here is the step by step on how to do it.

Be sure that transmission fluid temperature is at least 104° F (40° C). To access check/fill plug: In the engine compartment, remove clamp from air hose behind cooling fan. Separate air tube from the hose and push the tube back towards the transaxle. Remove the clip holding the two power steering lines together. All Models: From underneath vehicle remove the transaxle check/fill plug with engine running. Fluid level should be even with hole. Add fluid as needed until fluid flows from hole. Replace check/fill plug and torque to 9 ft. lbs. (12 Nm).

On the driver side of the transmission pan there is a fill plug. The car must be in the air and level. With the car running fluid will run out of the plug hole when it is full. This is no fun without a lift.

If you are looking to check the fluid levels and add transmission fluid you will need to first purchase a fluid pump at your local car repair store. Most run between $10 and 25$. For best results, run your car for a few minutes to bring the fluids to operating temperatures before attempting to add fluid. Be careful of hot surfaces and liquids.
It is difficult to check the level of fluid in the 2001 Honda passport because it lacks a dipstick. Instead, you will have to get underneath the car and check it at the Automatic Transmission fluid pan. This is located approximately below the center of the rear passengers seat on the underside of the car.
To check the fluid, remove the top most bolt on the automatic transmission fluid pan (most use a 3/4 inch socket). Use your finger or other object to see if the fluid level is at the same level as the drain plug. This can be difficult to do therefore it may be easier to add fluid until it is full to verify that you are at the correct levels.
To add fluid, remove the top most bolt on the automatic transmission fluid pan (most use a 3/4 inch socket). Using the fluid pump, slowly add transmission fluid until it starts to drip out. Replace the bolt. Take care not to over tighten the bolt.
If you want to be thorough, start your car and while your foot is on the brake, run your transmission through the gears slowly. Turn off your car. Remove the fill bolt and check the fluid level again. If it is not full see the previous steps. If your levels are OK, replace the bolt and you are good to go.
