Should I have the transmission oil changed in my BMW 320d's "sealed for life" automatic gearbox?
Should I have the fluid/oil changed in my automatic gearbox? I have a BMW 320d SE auto on a 54 plate with 76,000 miles. BMW say it's sealed for life, but I hear that it's best to ignore that and have it changed to increase longevity and avoid expensive failures. Is that so?
It can be done, but it has to be done at the right temperature and pressure, so it's best done by a member of www.fedauto.co.uk.
