Mine does the same thing. With the gear selector in L, above about 20 mph I can put the pedal to the floor and the trans will hold 2nd gear. Technically this should be 100% load (or 99 LOD indicated on the SG) but mine only reads about 40 or so. I think on some older vehicles this reading is a measure of actual torque or HP compared to maximum engine torque or HP at any rpm. So even though the engine is generating as much power as it can at 3000 to 4000 rpm, it would still generate more at wot at the 5600 rpm red line.
I use the MAP reading as a more accurate gauge of engine load. With the engine off, pressure is balanced between the intake manifold and outside atmosphere, reading 14.3 psi (0 MAP is essentially a perfect vacuum). I aim to accelerate to speed at about 10 and cruise at 55 mph is usually 7.0 to 7.2. After the TC locks, about 13.5 will cause it to unlock, which is about 95% actual engine load.
