Where is the transmission dipstick on 1995 Isuzu redeo?

There is no transmission dipstick. You have to both check and add fluid to these vehicles from underneath the vehicle. Find the transmission fluid pan and you will find two plugs. The lower plug will drain the pan and the upper one you can add fluid or check the fluid level. You will know that the level is correct when the plug is out and fluid barely leaks out of the hole. You don't want a lot coming out because you don't want to overfill. In order to get it into the hole you have to be some sort of tube to attach to the top of the bottle. They sell these types of tubes at your auto part store and they just screw on. It is very awkward, but you can actually put the bottle high enough to get the fluid in if you put it right to the left of the pan. The first time I did this on mine it was a pain but once you figure it out you will be good to go. Let me know if you have any other questions about your vehicle.
