Is Esso trans oil green or honey? I heard it's green but bmw x5 owners who use vw/audi trans fluid says it's honey.

I am trying the drain and fill method of changing the fluid because I don't think the shop used the correct esso fluid. I asked them and all they will say is they used oem compatible. Well I think that is what is causing my humming noise. Can I do the drain and fill method if I don't know what fluid is in it already?

Confusion sometime arises because it's ZF transmissions with the GREEN type plate that use the LT71141 fluid.

As always thanks RRPhil. Do you think it's okay to do the drain and fill method and have fluids mix? And so any fluid from audi/vw/mercedes with lt71141 is the same fluid just different bottle right?

you'll always get a mix of fluids with the drain / fill method as it only really changes about 50% of the total fluid each time. I'd suggest doing 1 fill, run it for a short while ( i think it just ran it at standstill for a few minutes cycling through the gears whilst foot on the brake ) to mix it, then do it again. That way you'll have done 75% change. An then after that, drain/fill each year, or a certainly more regular basis.

The Esso stuff is honey coloured.

Dunno about the stuff from VW. I sourced the Esso stuff from an oil dealer here in the UK. Was definitely cheaper than any dealer stuff, plus I knew it was the right stuff.

Yes, all of these fluids are genuine Esso LT71141 :

ZF Lifeguardfluid5 (ZF p/n S671 090 170)
Audi / VW p/n G 052162 A1 / A2 / A6
BMW p/n 8322 9407807
Citroen p/n Z 000169756
Jaguar p/n JLM 20238
Mercedes Benz p/n A 0019892203
Peugeot p/n Z 000169756
Porsche p/n 999.917.547.00

The fluid capacity is 9.9 litres and, of that, you’ll probably be able to drain off around 6 litres at most. Therefore if you drain & refill once you’ll be running with 61% of fresh fluid, twice increases this to 84.5% and a third time would take you to 93.9% (assuming, of course, that it's fully mixed in-between). However draining & refilling 3 times means you’re effectively throwing away 8.7 litres of your new, very expensive, fluid :( . The only way to avoid this would be to hook the transmission up to a flushing machine – but maybe this would cost more than 8.7 litres of LT71141?
