Put it in first gear,release the clutch and drive,engage clutch,put in neutral and wait until it idles,engage clutch and put in second gear and drive............
From third gear to second do the same,only when its in neutral rev it a bit,let it idle and engage clutch again and put it in second.
First gear only when car is stopped.
Beware the engine idles slowly,when the revs are too high the gears will grind.
O........don't repaint the car,,,,it looks fantastic
