A method for controlling gear shift from a forward gear to a reverse gear in a transmission arrangement (100, 200, 300, 400, 500), the transmission arrangement comprising a first, a second, a third, and a fourth planetary gear set comprising a sun gear, a planet carrier and a ring gear, respectively, wherein said transmission arrangement further comprises a transmission housing, an input shaft and an output shaft, wherein - the planet carrier of the first planetary gear set is operatively connected to the output shaft of said transmission arrangement; - the ring gear of the first planetary gear set and the planet carrier of the second planetary gear set are operatively connected to each other; - the sun gear of the first planetary gear set and the sun gear of the second planetary gear set are operatively connected to each other; - the ring gear of the second planetary gear set and the planet carrier of the third planetary gear set are operatively connected to each other; - two of the sun gear, the planet carrier and the ring gear of the fourth planetary gear set are each operatively connected to a respective one of the input shaft, the sun gear, the planet carrier and the ring gear of the third planetary gear set; - a first locking mechanism is arranged for selectively locking the ring gear of the third planetary gear set to the transmission housing; - a second locking mechanism is arranged for selectively locking the planet carrier of the second planetary gear set to the transmission housing; and - a first connecting mechanism is arranged for selectively connecting the planet carrier of the second planetary gear set to the ring gear of the third planetary gear set; the method comprising the steps of: - positioning the first locking mechanism and the first connecting mechanism at least in a partially engaged state for reducing the rotational speed of the planet carrier of the second planetary gear set; and - positioning the second locking mechanism in an engaged state when the rotational speed of the planet carrier of the second planetary gear set is below a predetermined threshold limit. - the planet carrier of the first planetary gear set is operatively connected to the output shaft of said transmission arrangement; - the ring gear of the first planetary gear set and the planet carrier of the second planetary gear set are operatively connected to each other; - the sun gear of the first planetary gear set and the sun gear of the second planetary gear set are operatively connected to each other; - the ring gear of the second planetary gear set and the planet carrier of the third planetary gear set are operatively connected to each other; - two of the sun gear, the planet carrier and the ring gear of the fourth planetary gear set are each operatively connected to a respective one of the input shaft, the sun gear, the planet carrier and the ring gear of the third planetary gear set; - a first locking mechanism is arranged for selectively locking the ring gear of the third planetary gear set to the transmission housing; - a second locking mechanism is arranged for selectively locking the planet carrier of the second planetary gear set to the transmission housing; and - a first connecting mechanism is arranged for selectively connecting the planet carrier of the second planetary gear set to the ring gear of the third planetary gear set; the method comprising the steps of: - positioning the first locking mechanism and the first connecting mechanism at least in a partially engaged state for reducing the rotational speed of the planet carrier of the second planetary gear set; and - positioning the second locking mechanism in an engaged state when the rotational speed of the planet carrier of the second planetary gear set is below a predetermined threshold limit.
