How can you add transmission fluid to 1999 Isuzu Trooper?

Answer 1

The 99 Trooper is considered a "sealed trans", it does not have an available dip stick to check the fluid levels. To add Transmission Fluid, locate the transmission main pan from under the vehicle. You will see 2 large bolts, one at the top corner of the pan, one at the bottom. The top is the fill plug, the bottom is the drain. To begin filling, make sure to chock the vehicle wheels on a level surface, leave the vehicle running in neutral with the handbrake ON. Remove the fill bolt and take notice if fluid dribbles out. If fluid gently dribbles out the transmission is filled to the proper level, if not fluid comes out then begin adding using a fluid pump.

Make sure you check/fill with the vehicle running in neutral. Fluid must be circulating to get an accurate reading.

If the transmission is a standard transmission, there should be a plug on the outside of it that would need to be removed and usually you would put your finger in to see where the fluid was and fill accordingly.
