Bongo Fury

From what I remember, he did his new shape using 4 litres & 100 miles later found it wasn't enough, might be wrong though

Big daddy - ha ha!

Dandy, that's a good point - there are two different types of filter housing too; I guess that's the different types of 'box?

Mine was the 4-bolt type filter - I think it's the earlier type. So my findings will relate to that.

Good tips all round. I'm put off from DIYing it though as I worry about access problems, dust / dirt being blown in to exposed components (I'd be working outdoors, on my drive), getting a good gasket seal on refitting and (now) capacity issues. It should be a quick job for Wheelquick (and they'll need the engine cover off anyway as I'm going to have the n/s disel pump O ring done at the same time). I love the achievement of DIYing things, but will probably pass on this one.

I've just been down to Dunnings autos to have a chat with the guys, mainly because I was wondering about the oil in the cooler & pipework. They reckon that if you drop the pan & filter, up to 6 litres to refill, BUT there will still be a load in the torque converter, oil cooler & pipework maybe as much as another 4 litres. When they do a gearbox rebuild they reckon it's about 18 pints (just over 10 litres) to refill from clean.
If you want to drain a bit more, removing the oil return form the oil cooler, & turning it over to pump it through is possible, but could result in it running dry & causing serious upsets if you turn it over for too long
They didn't seem to think, getting all the oil out was too much of an issue to worry about.
I was wondering whether which end you jacked the bongo up would have an effect on how much comes out?, ie if it's sloping backwards, a bit more may dribble back down the pipework from the cooler?
It's all food for thought
Just bought 10 litres of DIII ATF for £29, hopefully it'll be enough to replace the steering fluid when I swap the refurbed rack as well as the gearbox.

Further point to consider, is the pipework/cooler even doing it's job? I remember seeing a post from someone about the pipes being full of "mud" I think the description was. Maybe this could also be part of the reason for differing amounts needed to refill?
Can you tell I'm bored

If you're bored and really keen you could get a second hand power steering pump rigged up and connect it to the gearbox to cooler pipes - that'll soon flush it out. When overhauling auto boxes I also used a remote filter housing connected onto the gearbox via the cooler pipe ends and idled the engine in "P" for 15 mins - that flushed out the torque convertor pretty well.

I was thinking one of those little pumps you power off a drill, using a jug or bowl as a sump. What do you think?
I like the idea of the filter to flush the torque converter, any specifics on what you used?

Need to be a pretty high power pump to really flush it out - the PAS pump certainly is.

It was some kind of remote oil filter setup from a BMC engine - perhaps a Mini - one with a paper cartridge element

Sounds like I've got a scrappie trip coming up then

What about an Air Line

Better than nothing, although it might tend to force the crap into the crannies in the cooler

Or out of the crannies,

Don't go sticking the air hose up the Crankies
