If it is difficult to move the AT handle to the 1 or 2 position in the '95 Nissan Sunny Super Saloon how do you fix this?

I had a similar problem with my 93' Sentra.

The solution in mine was to let go the Shifting cable from the transmission and try and pull the lever. If it is still stiff, this means your cable is kinked somewhere inside the transmission arm. Simply go to the parts store and pick up a new one. Now, If it moves freely with the cable disconected from the tranny, we have a problem. This means that somewhere inside the valvebody of your transmission there is a issue. Usually dirt or something like that. My recomendation for this would be to drain your transmission and your torque converter and replace your tranny filter.

Hope it helps.
