Where on a 2.4lt 1989 Nissan Pintara do you put the transmission fluid? I cannot seem to find where it would go and my vehicle is not changing gears properly.
As far as I can tell, the workshop manual makes no mention of a fill plug.
After draining out the old transmission fluid via the drain plug and reinstating it, one option is to introduce the new ATF through the dipstick channel.
Page AT-85 of the manual says that the transmission takes 6.8 L of ATF.
There is not a location to refill the ATF on this vehicle.
You will need to take it to a shop where they have special pumps to remove and replace the current ATF in your transmission.
