OK I did transmission fluid flush on my 02 4.4i

[Whitecat]

Hello all,

Flush oil transmission done today by transmission specialist.
My X is at 75k miles and i've decided following shop reco, to let them perform the changed.

Special equipement is required to complete full flush including torque convertor (car was running during the entire procedure)

Oil transmission was really dark and no question ask that this oil needed fresh blood. Shop specialist used 16 litters of wynn's oil syntec OEM recommended or approved by BMW http://www.wynnsusa.com/pdf/12711_SynMultiATFSpecs.pdf ...adding also the wynn's cleaner detergent.

As for the transfer case and differential oil changed claimed as life time by BMW ...well ...the shop transmission specialist did confirmed that oil was same as new and there was no reason to change.

As of now, transmission shifting is really smooth ...but it is difficult to feel the difference....i'll keep you posted

Cheers !

This is a great thread. But what is the Transmission Fluid used in a 2004 3.0 X5? The one the OP uses is incorrect for my year and model.

Although the 3.0 diesel models in Europe got the ZF 6-speed transmission from 2003, the 3.0 petrol models had to put up with the GM 5L40-E transmission (A5S390R) until the E70 came along - so your fluid is Dexron VI/Texaco ETL 8072B.

Thanks for that Phil! So BMW would use that Texaco ETL 8072B? Or is there a different brand? Being a GM Tranny anyways. Maybe there is a recommended other brand?

Interesing on the Wynns...

I would assume/presume a tranny shop would have used a direct 71141 equivalent and roll the dice with a *compatiable listed* fluid.

Hello, my fisrt asked to the transmission shop owner 30 years experience (he has a chemister University degree...) was to go with the OEM exact fluid type based on my ZF transmission Model. He explained that the wynn's was an absolutly no problem and approved by BMW replacement. Company give 7 years (i think) warranty on their product ( see my hyperlink)

I understand that this is an Equivalence and link with some limited inventory space at the shop.
I'm not expert but this transmission shop is known by other good garage as best in my area.

It was approved by your shop, it wasn't approved by BMW. That fluid is a Dexron fluid.

Agree, i should'nt used the word approve but equivalence
Thanks JCL ;-)

Thanks for this. I read the link to better understand the terms of their warranty.

At your vehicle mileage (75,000 max, any more than that and there is no warranty applicable...) they limit the warranty coverage to $500. They don't cover any faults that show up in the first 500 miles after the flush, they call that the grace period. And you have to keep flushing it with them every 30,000 miles to keep the warranty active. That is quite a restrictive service warranty.

Good luck, hope it works out for you.
