I need to replace the transmission fluid in my 1999 isuzu rodeo 4 wheel drv...auto trans.....6 cylnder....it is supposed to be done at the dealership....but i want to know if i can do it myself....ive been trying to locate a plug that i can remove and pump it in...is this possible

You need to take your vehicle an have trans fluid changed . What light is flashing ? Trans , check engine etc... Have it checked for codes .

1999,.lost the operators guide, sure.....
no isuzu dealers here (to ask)

what trans.? 4speed auto.
5 engines, used, im not too sure all 5 use same trans,
diesel or Gas?
ill look in the USA page.
i see 18.2 pints.
under bulletins, is see, the
4L30E/4L60E that states

The correct fluid to use in all Isuzu vehicles equipped with the 4L30E or 4L60E automatic , ill guess this. is YOURS?
transmissions is
DEXRON-III with a G-License Number (G-34318)
, Isuzu part number: 2-
90531-815-0 or equivalent
(see figure 1).


use the newest highest number Dexron, Dexron is downward compatible to #2.

Drain transmission fluid. Remove transmission oil pan. Remove and replace transmission filter. re-install oil pan with new gasket and refill with new transmission fluid.

transmission oil is red pull the dipstick out & check the color, also the transmission dipstick is a lot longer than the engine dipstick......hope this helps.....cheers

what size engine?

Usually you just fill with a funnel, unless it is at an awkward position.

Auto Trans.and manual Rodeo has no dipstick. Fluid levels must be checked from underneath the vehicle on a lift at the shop. It can only be filled from underneath the vehicle as well.

trans. fluid and filter needs to changed

more than likely is a bad strut! if the drip is from pan replace gasket.

it normally is under the hood on the driver side and you see one that says engine oil and you may have to look on the other side to find the one that says transmission

There are two drain plugs on the bottom of the pan. remove the lower one to drain the trans fluid. To refill, use a pump and pump the fluid into the upper drain plug until it seeps out and re-install the plug, similar to refilling a manual trans.
Once this is done, Start the vehicle and run it for about 3 minutes, shifting through all gears (do not drive vehicle Remove the upper drain plug and let any excess fluid drain out. Done. This is as per Mitchell OnDemand.
