99 1.8 Possible to overfill an IB5 gearbox ? - jp147
The 1.4, 1.6 and 1.8 litre petrol Ford Focus are fitted with the iB5 manual transmission whereas the 2.0 litre petrol and 1.8 litre turbo diesel are fitted with the MTX 75 transmission.

Because my Focus is a 1.8 petrol it uses the iB5 gearbox.

I have read conflicting reports on the internet that with some manual gearboxes it is possible to overfill the box with oil. I think they mentioned that if the gearbox has a hole for checking and also another hole for filling then it is possible to overfill with oil whereas if the box only has a single hole for checking and filling then it is not possible to overfill with oil.

Does anyone know whether it is possible to overfill the iB5 transmission with oil

thanks.

Be warned that they use different oils;you can tell which g/box is fitted by the gearlever in the car.MTX75 has a lift-up detent under the knob to allow reverse to be selected;the iB5 has only a spring detent to stop reverse being selected.The reason for the reverse detent and different oils is that MTX has synchro cones on reverse.
