AUTO Gearbox Fluid

[faygun]

Hey guys,

How often do you think is appropriate to change the gearbox fluid? I want to take good care of my car. I dont trash the car. I drive it hard every now and then and use the SSS mode when im driving it hard.

Thanks in advance.

As far as I knew, the Auto box on Ba's was a sealed unit???

Na mate! If she was sealed mine wouldn't have sprung two leaks.

Just get it changed when the service book says to.

Ford believes that you dont need to change the auto gearbox fluid in the EL, AU and the BA models unless you do some heavy towing or the car is a police car or a taxi.

I would advise to change the auto fluid at no more than 40000 km's with the turbo if not more often as the extra heat of the turbo and extra power loads can burn the fliud do not forget to have the filter inside the pan replaced at the same time.

its suggested that when towing and the like to change the oil every 50,000kms. The trans has a sump like a motor so you can remove the sump and drain it then change the oil as well. the trouble with this is that your only changing about a third of the gearbox oil as the torque convertor holds about 7 litres of oil I think it is! So really the only way to change the oil properly is to drain the sump, change the filter, reassemble it all and then at transmission places and dealers they should have a pump/filter system that they plug into the trans cooler lines that they are able to flush the whole trans system with new fluid! not sure how long it takes but it used to cost about $150 due to the amount of fluid used! As another point. make sure that the gearbox adjustments are not touched! the reason for this is that the computer adjusts the clutch pressures and the like to suit the wear of the gearbox. you go playing with the adjustments and the gear changes will all turn to sh*t! Try putting an ecu out of a car that has done 75k in a new car and feel the gear changes! just horrible! When a new trans is fitted we put the computer in "green" mode which holds the clutches at a higher pressure until the parts have all bedded in and the like!
