and people were also putting the wrong oil them, which also can cause problems.

EXACTLY, mik, spot on mate

Any time one buys a new car, it always pays just to do a full service of everything [yourself] then YOU as the new owner, knows the job has been done right, from the start
Which is what I personally, am working on doing

G'day,how's Sydney?You sound as if you know BTR boxes.Is the Speed Transducer another common leaking point on AU's or is the fluid likely to be coming from the exten housing gasket on my ser 3 wag;162k.

Mate it is a lot more common coming from the speed sensor when the o rings goes old and hard but have seen the extension housing leaking to its hard to say not looking at the car but it is easy to pull the speed sensor out and change the o ring that would be the first thing I would do if your not sure were it is leaking from and you are working on it yourself

Thanks mate,will change the o-ring this w/e.I also read from old blogs[2009etc]that fluid could also come out of the breather which is also on top of the housing.It all being so hard to acess without the bright lights & hoist doesn't help but I s'pose life wasn't made to be easy.

Yer start with that oring you can get bright torches these days oil really shouldnt come out of the breather unless you over full or getting really hot good luck

G'day Sydney,Yeah I changed the o-ring on the speed transducer but the leak is still there.From what I can see it looks as if it's the extension-housing gasket which has splined-bolt heads[not sore of correct term]so I s'pose it'll have to be a pay workshop job & expensive.That, or just change the fluid & forget about the leak.Any advice appreciated.

You might want to think about the following as well, while you are under there...
- rear main engine seal
- rear welch plug
- rebush oil pump, m/c cover, fit seal

If the trans is out you should get a full reconditioning ... (new?) torque converter, clutches, bearings, bushes, because you don't want to have to go back there - just removing and replacing is many hours, and costly if commercially done.

Thanks for reply but what you're talking about is thousands of dollars worth mate.Yes I agree the rear extension seal should be replaced but where's the welch plug?I mean the BTR 93 is working ok it's just a persistent leak coming down from the top of the extension housing.I'll see what the experts want to charge.No the trans is not out;I drive it every day.

Its probably the actual speed transducer. These can leak - you can pick up one from Ford for about $80. I think they are cheaper online.

You can also get an extension housing service kit that contains the bush, rear seal and gasket. Can't remember if the bolts are 12point or spline drive, but either way, the socket is going be the cheapest thing you will buy. You will however need a press to get the bush out and obviously the spacers needed to press the bush out - if in fact it is leaking from the rear seal. Worst case scenario, take the extension housing off and take it to a transmission shop and see if they will change the bush over for you.

Quick followup to my issue guys

Spent $250.00 having FLUSH etc done on my box, but found metal and other crap in the box, so it's beyond it's used by date sadly

NOW have a 5 speed ready to go, just picked up the Pedal Box and now just need the ring gear and cable, then should be set to go

I appreciate ALL the previous help and advice, but I've now chosen to convert to 5 speed manual and get the most of the performance from the XR6 that I can

I know that this isn't the thread for it, but IF anyone has any info/ cables / ring gear to achieve the conversion, then please inbox me.

Cheers,
Dave
