Auto box on 71 series

Hello guys,
I'd like to change the oil in the auto box on my KZJ71 TLC before the end of
the month to be ready for Salisbury plain. Not having done this in the past
and needing to check out what to do I could not find a clear process on the
internet, so climbed underneath and saw the drain plug, but did not see
where to refil.
Also, do I need take the bottom off to inspect/clean/replace the filter (I
guess it will have one). The TLC now have 132 000 KM on the clock.
One of my biggest problems is locating a maintenance manual for my Jap
import 1993 model 71 series. I found a manual for the 3L 1KZ-TE, but this
only covers the engine and excludes the gearbox, transfer case etc.
Cheers
Dirk

Hi Dirk,
If your auto box is anything like the one in the 80, there won't be a
filter as such, but a sieve that might need cleaning, although the
mileage is still relatively low - if theoil looks a bit dirty then
might be worth it.
You will probably have to fill it from the dip stick tube - a real
fiddly pain in the rear, but not something that you have to do that
often so not a major hardship.

Hi Dirk,
This is the method I use assuming you are changing the trash filter in
the sump.
Drain the oil from the pan and remove the pan and filter. Now measure
how many liters of oil you got out. You should be able to buy a
aftermarket cork pan gasket rather than have to glue it on like the
factory does. If so clean and dry the gasket faces and apply a very fine
film of Loctite 515 to both sides of the gasket (if any gets into the
auto it does not matter as it will dissolve in the ATF and do no harm
unlike RTV) and refit the pan tighten the bolts gently so you don't
split the cork gasket.
Buy an ATF funnel if you don't have one, basically a big funnel with a
very small outlet to fit in the dipstick tube.
Now put in through the dipstick tube the same number of liters as you
have taken out initially. Say 4L if we assume the total capacity is 12L
(a 80 series is 16.5L) we still need to replace another 8L. Don't start
the engine yet.
Go to the back of the radiator and undo the clips on the two rubber
hoses that attach to the radiator pull these two hoses off and point
them down into a bucket. While you watch the hoses get someone to start
the truck (while in park) when you see oil being pumped out of one hose
stop the truck. Recconect this hose to the oil cooler in the rad (this
is so you flush out the oil cooler with fresh clean oil). Now connect
the other one and disconnect the other end of this hose and point it
into the bucket. Now when you start the truck the oil is being sucked up
out of the auto sump and pushed through the oil cooler and dumped into
your bucket with no oil being returned to the sump.
Now start the truck and run it until the hose in the bucket gurgles a
bit now turn off the engine. Check how much has come out say another 4L
so we are now upto 8L replaced.
Repeat until you have removed 12-14L of oil into total. Recoonect hose
and top up the auto level. It should be checked in park with the engine
running after shifting through all the gears. Once the level starts to
move up the dipstick it will rise quite rapidly so fine tune at 1/2L at
a time. It will take several dips to clean out the dregs running down
the dipstick tube from filling it to get a accurate reading after
filling down the dipstick tube.
You have now successfully replaced all the fluid with minimal cross
contamination.
Note to John Byrne: You can do your 80 in exactly the same way John when
you switch to Amsoil if you start with 19L and end up with 1-2 left over
that is about right.
