Thanks for you interest Jason and Athol,

Thanks for that encouragement Jason.

Yes - (her... I mean) "the" body is in really good nik!
Bought her for $650 from a bloke across the road from where I work, and 
right where my old Toyota finally carked it!
Basically, I jumped out of that old car into the other.
Metal Recycling truck came around the next day and picked up my old Toyota

and gave me 200 Bucks!
So I only spent $450 on the deal and are driving around in a much better 
car!

But . . . . I organised a Roadworthy Inspection yesterday and it revealed 
some 45 odd items to be rectified!!!  (Doable though)
Mind you, it drives well (except for some front end issues) - the breaks
are 
good, the engine is sound, the body is good.
I know I'm taking a risk with the tranny - but bugger it! - you know 
hat!!!  -  I'm going to fix her and get her up to scratch and take my 
chances with the tranny.

- Like I said, I really do like the car.

Ok - That helps my understanding. So what you're saying is it's a "Rob
Peter 
to pay Paul" scenario.

I've done a bit of reading up about the modulator but still can't grasp
the 
concept of the vacuum/hydraulic relation****p.
It's a good thing i'm noy a mechanic! - nor can I spell!
I guess I was hoping that it would be an "easy" fix.  ie. drop oil, change

filter, adjust band, frigg about wirh the modulaor . . .
But now I know the problem is with the clutch packs.

Nevertheless, it was your initial post that made me realise that adjusting

it could make difference - and it has!

After discussing this with my brother we came to the conclusion that the 
original supplied modulators (OEM) didn't need adjustment because they
were 
"exactly" suited to that model of gearbox and engine.  These days it's
more 
conveinent to have a "one suits all" approach for replacement simplicity -

and then adjust it. But you need to know how to do it properly - I fluked 
mine - better at least.

It's my first Auto, and maybe I'll look at replacing it when it finally 
goes - to a Manual!!!

Steve.
