Kindly somebody help as to what could be the issue. Thanks

Did you change and refill the transmission fluid - top off the fluid by making sure you checked the final level while the transmission was up to normal operating temperature?

Check the transmission when warmed up - change to each gear manually - then recheck the fluid level, add / drain as necessary to achieve the correct level at operating temperature.
