1999 E36 323i Sport Auto Touring (UK model).
I know it's supposedly filled with "Lifetime" fluid, but as filters are
available I think I'll change it while the trans is still sound.
According to TIS/ETK, the transmission is an A5S 310Z-OJ and the fluid is
Esso LT71141. Are there any alternatives to this fluid and typically how
much do I need to buy? TIS says 3L, but with torque conveter drained too,
7.1L. I take it that I'll need approx 3L?
I've go the procedure printed off from TIS so that's not a problem. I just
need to source the fluid.
Thanks for any info.

The filter isn't like an engine oil filter - it's just a gauze to prevent
a foreign body entering the pump. It doesn't clean the fluid in any way.

Why are these listed as a service item by both BMW and ECP? I had always
imagined that you just clean and replace them. I seem to remember there
being 2 filters, the other hidden inside another 'inner pan'. This
replacment may be this type? Must do more research before getting stuck in.
Cheers,
