Well the auto finally gave up. Turns out the clutch packs fused together. Picked up a second hand box but can not afford the transmission place to install it so will be doing it myself. Can anyone give me some hints or tips?

car up on car stands to be as level as possible
drain out the tranny oil
undo centre metal brace running north south under the car
remove both drive shafts
remove intrim shaft
undo speedo cable
undo oil cooler pipes and mark which one goes to the front pipe of the box

through tin inspection plate at the end of the motor sump
undo torque converter bolts 17 mm from drive plate...

undo gearbox mount remove so the box will tilt down easily
undo gear shift cables
unplug wiring looms to the box
undo starter motor

undo all the gearbox bolts to the engine block

with a floor jack and a flat piece of timber support gearbox and lower to ground

going back in make sure torque converter is in all the way to the oil pump

extra info
the torque converter is to be fitted into the auto box while the box is still out of the car
if you have taken out the torque converter /the box has to be tipped up on its end to fit the converter back in properly

fitting torque converter
Rotate the converter. On most applications you will feel it drop into place. Continue to rotate. A second drop will occur. You must be certain that the converter has been turned more than one full revolution to insure correct positioning on the stator/input oil pump drive cog/turbine shaft.

once the torque converter has been lined up with the oil pump drive cog
the torque converter will stay in alignment by itself
care has to be taken that the torque converter doesnt slip out while putting the box back into the car

when you have the box bolted to the engine again it is safe to tighten the torque converter onto the drive plate and not before
fitting to drive plate
you spin the torque converter to line up with one of the three bolt holes of the drive plate ///after the first bolt is in then you turn the engine if you cant line up a bolt hole turn the engine till you can get a bolt started onto the torque converter
the turn the engine to the next bolt hole
the torque converter will self align back onto the crank as you tighten it back into place

(will try to simplify this statement )
(Incorrect fitting will cause the torque converter to slip out of the oil pump drive cog .forcing the converter flats on top of the oil pump drive cog , if you try to tighten up the box the oil pump will break .)

auto oil pump
this step is too important to stuff up

only worry about the line up problem if the torque converter falls out
also dont damage the oil pump seal

when you look at the torque converter shaft that goes into the auto box
you will notice two flat surfaces on it at its end

the pic is the autos oil pump the oil pump drive gear (arrow) inside of the automatic box has the same two flats those need to line up

thats where you need the torch to look into the oil pump so you can see if the flats will line up

All done now ended up getting the transmission place to do it. The wife is happy now O/D works and gear changes nice and smooth.

Above is great however is often worth the cost to hire an engine crane or borrow one if you know someone with one and just lift the whole lot out.

This also gives you the chance to do a good service, fix any annoing oil leaks and just generally do a good job if it

Looked at this as i usually do everything myself but by the time i bought oil, crank seal , new cv boot and the time off work it was cheaper for them to do it. I made sure they put a new crank seal in. Only cost $300.
I had no oil leaks but i had to use five cans of degreaser the clean up the secondhand box. My engine was clean and shiny and the box had an inch of grease and crap on it.
