Thoughts on Changing Transmission Fluid

[BMW_E53]

Decided to start a new thread on this topic. Have any of you guys ever changed the lifetime oil or ever thought about it?

it should be done as regular maintenance no fluid is life time I don`t care what anyone says.

I got my X5 with over 100K miles on it. The trans would slam in to gear when taking off from a rolling stop.

Had the trans filter and fluid changed and the torque converter flushed. Trans shifts like butter now. There is no such thing as a lifetime fluid or filter. Unless of course you want the life of your car to be shortened.

Hey Brandon002 I have the same year and model as you. Did you change the oil yourself? At what mileage did you change the oil?

[Brandon002]

I had a local german indy do mine. It was 419 including parts, labor and fluid. I figured it was worth it when parts and fluid alone were going to cost me 250 minimum.

Having them do it got me a torque converter flush too, which i wouldnt have been able to do at home.

[Brandon002]

146k miles.

Lifetime .... of the gearbox..... but if you want it to last a lifetime of the car, you gotta change it
