I am researching before the actual flush,my tranny was rebuilt by the local shop and they poured dextron VI into it,so I am getting shudders in the moment of Torque Converter lock up.I was able to find the fluid locally at Canadian Tire for $ 29.99 /5 liters container.
I read the label and it's got : BMW 7045E LA2634 LT 71141 .

Here's another thing I researched from Automatic Choice

Esso LT 71141 Transmission Fluid

Esso LT 71141 also know as LifeGuardFluid5 is a semi synthetic transmission fluid specially formulated for use in ZF five speed transmission units, although it is also required for the ZF4HP20 transmission. All ZF units requiring Esso LT 71141 can be identified by the colour of the ID tag, which is green. Please note that this fluid is not suitable for ZF six speed units which require LifeGuardFluid6 or LifeGuardFluid6 Plus.

It is becoming increasingly important to use the correct grade of oil in late model transmissions as failure to do so can result in numerous shift and torque converter related problems with eventual failure of the unit.

ZF’s response to using alternative fluids is quite clear, they say the design specification of these units require the use of Esso LT 71141. There is no alternative or equivalent oil, Esso is the only supplier of LT 71141. The transmissions are not designed to run on any other fluid and if installed you run the risk of premature failure. The transmissions are equipped with sophisticated torque converter lockup control (TCC) systems and the correct oil specification is critical to their function and operation. One of the main functions of the oil is to provide the correct coefficient of friction and cooling of the torque converter lockup lining during regulated slip conditions. The longevity of the lockup lining could be adversely affected by the use of the incorrect grade of fluid and in most cases deterioration in shift quality and lockup engagement is also experienced.

With this in mind it would seem unwise to supplement this oil with any other, as you could lay yourselves open to warranty claims upon any subsequent failure of the transmission.

Esso LT 71141 is an extremely well specified fluid and many of our customers have used it with success in other transmissions requiring high quality semi synthetic fluids such as DP0 and JF506E, a case in point is the Jaguar X-Type fitted with the JF506E transmission, if after rebuild these units are not filled with the recommended fluid, the oil pumps are often very noisy, sometimes to the extent that imminent failure is expected. On a couple of occasions customers have told us that they have drained as much fluid from the transmission and converter as possible, refilled it with Esso LT71141 and hey presto all is quiet.

Although we would always advise using the oil grade recommended by the manufacturer, it does seem that if you are unable for any reason to use the correct grade, you may find that Esso Lt 71141 will fill your needs for a premium quality ATF.

And yet another thing from other forum,the last thread especially:
Esso LT 71141 vs valvoline max life or castrol import atf - Bimmerforums - The Ultimate BMW Forum
But again I personally go with the BMW recommended fluid.
I am having the local tranny shop flushing the Dextron some time after new year holidays,and refill will be Exxon's Mobil ATF.
My shudders and slipping between 1&2 gear started after the fluid change(partial,no Torque Converter) by the shop that didn't care much about the brand and fluid specs.I didn't know of such a difference either since it's the first Auto box for me,may be the last one as well....
