WHAT IS A AUTOMATIC TRANSMISSION AND HOW DO I KNOW WEATHER IT NEEDS TO BE SERVICED?
BMW’s have used automatic transmissions ZF6hp and ZF8hp for many years ZF have been the main supplier of BMW transmissions which can be found in most bmw’s E series and F series vehicles later the ASIN 8 speed gearbox was installed in the front wheel drive and 4WD 2 series.
BMW recommend no service interval and say the oil is a life time oil with no need for replacment, as BMW class 100,000 miles as life time this would then suggest maintenance would be needed, ZF who supply the gearbox recommend a oil and filter replacement of the gerabox at 100.000 miles.
SYMPTOMS.
Signs of poor gear changes and jerking when gears are selected are the main complaints from customers this is caused by the transmission oil losing viscosity within the internal clutch plates, there are many oil gallerys and solenoids that need to be free from contamination to work correctly.
