Torque converter slipping
'93 Ranger 3.0/Auto/4x4 220,000 miles. Seems like the torque converter is not locking up anymore. Take off is fine, both normal and foot-to-floor. But, when I let up on the gas at any speed or any gear 1-2-3-OD, the RPM's drop to around 700-800. There is no engine breaking. I can manually down shift and there is no engine braking in any gear.... like the tranny is disconnected from the engine when you are off the gas. Yet, floor it, and it moves ahead fine at any speed. Several months ago, it would cruise at 70 mph at about 2,500 RPM. Now, it is about 3,100 RPM at 70 mph. Fluid is dark red, is clean, and smells fine; no burnt smell. I bought the truck last spring with 216K, and have not changed tranny fluid. Bad torque converter or something else.... any ideas?
