We have now come to the third and final of the mini-guides useful for those who want to carry out the basic Suzuki Swift Sport servicing on their own, for the 2018-19 model with a thermal engine.

In the first of the three guides, we explained how to make the engine oil replacement, explaining in detail all the accuracies one needs to have. We then published a second mini-guide with step-by-step explanations for carrying out the replacement of spark plugs On the Swift Sport.

First of all, it should be remembered that the inspection and maintenance plan recommended by Suzuki is to have the transmission oil checked every 30,000km or 24 months under non-severe vehicle use conditions. While transmission oil replacement is scheduled every 45,000km routes or every 36 months of use.

A final tip for gearbox oil.

Putting more oil than expected in the gearbox crankcase may not cause any damage, in the worst situation (exaggerating in sports use) it may just get too hot and partly leak out of the overflow tube.

Some 'shrewd' users of the group tell of finding themselves even better off adding another 100ml of oil beyond the maximum level (overfill), thus making the gearbox improves and becomes smoother.

The trick to making this oil overfill is to Lift the car from the driver's side only and then add these additional 100ml of oil.
