Nissan has fairly late gear engagement on the trans, which explains why I did better on the minivan driving normally than I do going easy on the VQ.

Lock up? As in the TC lock up clutch engaging? That was (under light acceleration) at 45 mph, never any sooner. I could watch the rpms drop a few hundred and feel it lock up no doubt at that speed. But i know that my auto would shift into 4th (which is o/d, i mean all o/d does is either enable or disable 4th gear) around town going slowly at like 25-30 and rpms would drop to like a 1000, nice and low. I dont get why the FSM says o/d doesnt egnage til 75 or whatever you said earlier
. Also i dont see why the engine would be less efficient with o/d than overdrive off. If you going slow and not acceleration much at all your not going to lug the engine in a high gear or cause it to "hunt." If your in rapidly varying conditions like rush hour around town or something o/d off could be better but in general, I've never had a problem with it on. Even if you need a lower gear, its an auto itl take care of that..
