I have a 1975 case 450 crawler dozer. Just recently the torque converter pressure dropped off drasticly. It was maintaining around 40 pounds pressure when fully warmed up. Now when warmed up it reads almost zero, but will read around 20 when cold. I may replace gauge. (although gauge is not very old)
The crawler still works fine and I dont notice any loss in performance. The trans. pressure still maintians around 240 pounds when warmed up.
What would cause the torque converter to lose pressure if the gauge is not at falt? Any help would be much appreciated!
Thanks,

Steve
