First thing would be to check the fluid level in the transmission as per the Workshop Manual. If that is good (not too high, not too low, and not burnt or gritty), then check the line pressure. If it is low clean or replace the filter. Also check the final drive fluid level. It also can't hurt to check the air pressure in the tires.
