Castrol multi vehicle import atf crosses to BMW-lt71141. This also crosses to the LA number. This is what I have in my ZF tranny. I paid around 6 to 7 dollars a litre. If I remember correctly, (from NAPA). I bought 9 litres, and have some to spare. The trick is to find the little hand pump that threads the top of the bottle so you can pump it in the transmission.
