When pulling off from stand still the transmission will not shift from 1st to 2nd. The revs shoot up and car will not go more than 40kmh or so. This does not happen all the time but when it does the only way to resolve it is to pull over, stop the engine and wait till you hear a click from the dash area, I'm assuming it's the electrical resetting, then start the car and continue. Other than that the car runs well. Any insights on what this occasional fault could be? Thanks
