Changing your fluid is easy- took me less than 10 minutes

1. Jack up the front of the car and put a jack stand under it.

2. Get a 17mm and 24mm socket and a catch pail handy under the car.

3. Undo the fill plug first (17mm) in order to avoid glugging (don't forget the washer!!!).

4. Undo the drain plug (24mm) second and drain all the fluid out. make sure to position the waste pail accordingly.

A NOTE THE 6 SPEED TRANSMISSION USES TWO 10mm ALLEN SOCKETS FOR DRAIN AND FILL.

5. Screw the drain plug in (don't forget the washer!!!) and get a funnel with a long flexible spout (4 bucks from pep boys) and stick in the side of the fill hole.

if you use just the funnel with flex you'll likely have to remove your intake in order to fill from above. if you get some 3/8" rubber hose (about 18" should do) then you can seal off the fill hole (no leaking while filling) AND you don't have to remove the intake!

6. Pour new fluid in until it starts to come out of the drain hole (It is sideways) or around 3 quarts. YOU SHOULD ALWAYS FILL WITH YOUR CAR AT A PERFECTLY FLAT OR A SLIGHT POSITIVE INCLINE (front two wheels off the ground) this overfills the tranny as apposed to underfilling it and keeps things MUCH happier!!! this way it'll take 3 bottles of fluid and there's not guessing if you had too much spill out.

7. Put back fill plug. plugs should only be hand tight, torque specs are good, but don't hamfist them on or you'll be sorry!

DONE!

this is what your fill plug should not look like (dirty)

This was really easy and I am kicking myself for not doing it more often after seeing the metal shards on the plug. I used bg synchroshift after getting some info from RRE and robi.

GET 4 QUARTS.

TRANSFER CASE drain and fill.

Locate the appropriate fill and drain plugs. The ones for the transfer case are located closer towards the center of the car, behind the exhaust manifold. The fill plugs will always be located higher than the drain plugs.

Here is a pic showing the drain and fill holes:

the fill hole is a bit above the downpipe.

1. Open the fill plug first and clean the plug, be sure to remove both the plug as well as the metal washer. When I removed my transfer case fill plug, fluid ran from the fill hole so be prepared.

2. Put the oil catch pan underneath the drain plug and slowly undo the drain plug making sure that you also remove the metal washer. As the fluid drains, you may have to move the catch pan to prevent oil from leaking to the ground. drains real fast, only .6 quarts.

3. Clean the drain plug (you will find lots of tiny metal bits attached to the magnetic portion of the transfer case drain plug).

4. Once the stream of fluid has ceased, put the drain plug back. Be sure to remember to put the metal washer back on as well. If you have a torque wrench all the plugs should be tightened to 23 ft.lb.

5. Now, take the gear oil pump and run the hose into the fill hole. it's nice to have a hose long enough so you can sit the bottle on the ground and pump. but that just means more fluid that you're gonna have to pump back into the bottle when you're finished.

ALWAYS FILL YOUR TRANSFER CASE WITH THE CAR AT A PERFECTLY FLAT OR SLIGHT ANGLE SO YOU'RE OVER FILLING IT AND NOT UNDER FILLING IT!!! ALSO NOTE!!!

6. Pump the correct fluid into the diff. just keep pomping until fluid runs from the fill hole. it should take about .6 quarts.

7. Replace the fill plug. Be sure to remember the metal washer.

this is the rear diff

1. Open the fill plug first and clean the plug, be sure to remove both the plug as well as the metal washer. When I removed my rear diff fill plug, fluid ran from the fill hole so be prepared.

2. Put the oil catch pan underneath the drain plug and slowly undo the drain plug making sure that you also remove the metal washer. As the fluid drains, you may have to move the catch pan to prevent oil from leaking to the ground. drains real fast, only .6 quarts.

3. Clean the drain plug (you will find lots of tiny metal bits attached to the magnetic portion of the transfer case drain plug).

5. Now, take the gear oil pump and run the hose into the fill hole. it's nice to have a hose long enough so you can sit the bottle on the ground and pump. but that just means more fluid that you're gonna have to pump back into the bottle when you're finished.

ALWAYS FILL YOUR REAR DIFF WITH THE CAR AT A PERFECTLY FLAT OR NEGATIVE ANGLE SO YOU'RE OVER FILLING IT AND NOT UNDER FILLING IT!!! ALSO NOTE!!! clutch type differentials require a certain amount of friction to operate without chatter, you must use friction modifyer for fluids that don't already have it mixed in. that stuff stinks like fish too, so just get the stuff that already has it mixed in.

6. Pump the correct fluid into the diff. just keep pomping until fluid runs from the fill hole. it should take about .6 quarts.

7. Replace the fill plug. Be sure to remember the metal washer.

what are the drawbacks of overfilling??

you could get some leakage through axles or at least i suspect that's where it comes from... there's no pressure issues though.

ahh i see.its just frustrating sometimes that you know you really cant exactly put the right amount in since draining it doesnt completely empty it not unless you let it sit for a day.i changed all my fluids today and with the tranny i used about 2.80 qt give or take some spillage ;) while with the tcase i used about .75qt.

i just did my tranny and t-case but the damn rear diff drain plug wasnt coming off with my open end 24mm wrench, umm I guess I will have to opt for the socket tomorrow and finish the fluid swaping after the autox.

careful with using the socket you might not be able to remove one of them if the socket is too thick 1/2" unless you have a low profile wrench like a breaker bar. i don't know if you know exactly what i mean but i mean the socket on the wrench makes for an assembly you can't fit between something.

1/2 drive with with a longer 1/2 drive wrench works wonders. :)
