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 !
