Type of fluid for a 1998 Honda passport transmission

If it is an automatic Honda recommends you only use their own brand fluid, the same may apply for a standard transmission. You can't go wrong if you buy the fluid from a Honda dealer.

Drain and fill is about 5 and 1/2 quarts. Start with 4 and 1/2. Start it and get to operate temperature. Shut it off and check the fluid. Add till between the v marks.

There is no dipstick. The engine and transmission was designed by Isuzu up till 2002, and the automatic transmission was a sealed, no-maint. transmission. You will either need to purchase the special tools needed, or...........that's right, go to a transmission shop!!!

checking the transmission fluid of the honda passport is not an easy job. the cap is located at top of the transmission, determining the fluid level is by feel.

You add transmission fluid through the transmission dipstick tube, same one that you check the fluid level through. Use a small, long neck funnel that fits into the dipstick tube.

Sorry to tell you this, but there is no dipstick. Honda says this in its maintenance materials:
Check automatic transmission fluid level only if leakage is suspected.
Automatic transmission has no dipstick, so fluid level can only be
measured by checking fluid temperature with a PGM Tester and removing
the overfill screw. Refer to the Service Manual for details.

CHECK THE TRANSMISSION FLUID TO SEE IF IT IS LOW. THERE SHOULD BE A COLD LEVEL AND A HOT LEVEL. WITH THE TRANS IN PARK AND HOT, ENGINE RUNNING PULL THE DIPSTICK TO SEE IF THE TRANS NEEDS FLUID. WHEN ADDING, MAKE SURE THE PROPER FLUID IS USED. IF THE TRANS FLUID LEVEL IS OK BUT THE TRANS FLUID SMELLS BURNED OR IS VERY DARK THEN HAVE THE TRANSMISSION SERVICED WITH FLUID AND FILTER. I HOPE THIS HELPS. THANKS FOR USING FIX-YA AND FOR ANY COMMENTS. BEST OF LUCK

on level ground with the engine at idle pull out the dipstick wipe it off and check that the fluid is between the two marks.  Keep the level near the top mark but do not overfill.

If you have an automatic transmission, you should take it to a mechanic or at least purchase the special fluid temperature gauge needed to do it right. You add fluid through the overfill screw opening found on the transmission fluid pan (there is no dipstick or underhood component on the 96' and later models). It should be located in one corner of the pan; there's also a drain plug is more toward the middle. Never open the overfill screw with the engine stopped - it should always be running and warm.

For a manual transmission, the fill plug is also on the pan, but it is located on the side.

There is a metal fitting bolt close to the bottom of the transmission. You can unscrew that out and if transmission fluid comes out it's good. If this doesn't occur you'll have to get a pump and pump transmission fluid in it. This is the easiest with a lift of course. Don't you hate stupid Japanese ideas. Good luck man
