2001 Passport with automatic has no dipstick for transmission, how do I check level and where do I add fluid

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.
