Different vehicle manufactures recommend their gearbox oil to be changed at different intervals, some like BMW advise that their transmissions are sealed for life, however we all know that in the real world even the best specification oils degrade over time. We believe that the lifetime of your transmission can be extended with a service every 40 – 50,000 miles and in our experience not changing the oil has caused problems including slow or jerky gearshifts and in some cases premature transmission failure.
Simply draining and refilling the sump can leave up to 70% of the total fluid inside the torque converter, Valve body and cooler lines.
Hutfields have a gearbox fluid flushing machine which changes up-to 98% of the oil within your automatic transmission.
If you are experiencing one or more of the following problems this may be what you need.
■ Poor Shifting (shunting into gears)
■ Delay in engaging gears when the engine is cold
■ Gear Slip
■ Torque Converter Hunting (revs fluctuate whilst driving at a steady speed)
Whether you have a conventional automatic gearbox, a DSG/double clutch gearbox or a CVT automatic gearbox we can carry out a fluid exchange of around 98%.
We recommend your transmission be serviced every 40,000-50,000 miles, this will extend the life of your gearbox.
Regular servicing will restore the efficiency of your transmission and you will have that "like new feel" again along with many miles of trouble free operation.
Common issues with BMW and Land Rover automatic gearboxes
Several well known 4x4 vehicles known for their automatic gearbox problems, suffer mainly due to the servicing schedules stating that gearboxes are a sealed for life unit and the oil never needs changing. However ZF (the gearbox manufacturer) recommend the oil to be changed every 50,000 miles, we have serviced many ZF gearboxes that dealers have quoted thousands of pounds to replace all at a fraction of the cost of a new gearbox.
The Land Rover Discovery is probably our most common vehicle in for Gearbox flushing, with automatic gearbox problems starting from around 80,000 miles, some of the common faults are shuddering at approx. 2000rpm, slow gear engagement and gear changes when cold, torque converter lock up, to name just a few, and the cost that some customers are being quoted runs into thousands of pounds.
