Mach 1,

As far hitting OD under WOT, my tranny is having this exact problem. I'll be cruising the 1320 fine until I hit about 4500 in third and the tranny would drop into OD even with the tranny held in D...effectively killing my times and using up my OD. However, I don't believe this is suppose to occur.

If you simply leave the OD switch on and put the shifter in the OD position, the tranny will shift automatically anyway, so you don't have to flip a switch every time you want OD (as long as your TV linkage remains hooked up). But you can lock it out when you don't want it.

I think Lentech designed the feature more to allow racers to lock out their OD. That way, even at the end of the track where you let off the throttle, the tranny won't shift into OD. As I have 3.73's, I don't use the OD until I'm up to speed on the highway. In fact, I always drive in D when in town to save the tranny from shifting needlessly into OD and back into third everytime I hit 35-40 mph in town and then hit the gas. This avoids extra wear on the tranny.

I do think that Lentech has a nice product, however. I'll let you know how it performs when I get it bolted to the car.
