Through the dipstick tube that you check the fluid level at. Use a fine tube funnel to add transmission fluid.

If your automatic transmission in the dip stick tube located under the engine compartment.If you have manual transmission you might have to hoist the car up to service the transmission with fluid.John

Take the transmission fluid dipstick out of the tube in the engine compartment and using a funnel that fits nicely into the tube, pour in the correct amount of transmission fluid. Remember too that unlike engine oil, transmission fluid is to be measured when hot and engine is running.

Auto transmitions heve a fill tube in the rear of the engine compartment that are usually hidden by hoses. Manual tranmitions do not have a fill tube and have to be filled under the vehicle. There are two plugs. one will be higher than the other. You take out the top one and put your finger in the hole and see if you feel fluid. You fill it up until it starts to come out of the hole and hurry up and put the plug back in.( Be sure theat you put in the proper fluid)

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).

Unfortunately, you have a closed system transmission, there is no dipstick or filler tube. I have a 96 passport and to have fluid replaced in the transmission you need to take it to a garage that is equipped to fill closed transmissions. This generally runs about $100.00 at the dealership. I was on my way to get my transmission serviced when the trans broke. Don't wait long if you're having issues.
