Of course it's doable. If you cut and paste a switch into the harness
you can turn it on any time you want. However, I don't think you
really want it on. You will be lugging the engine and costing yourself
gas mileage if you defeat the correct mapping of lockup.
I wouldn't like it to be controlled fully by a switch without the
computer turning it on and off. I'm too forgetful and can easily
imagine myself coming to a stop with it still engaged! But a switch
that allowed it to lock up in 2nd and 3rd gear the same as it does in
O-Drive would be great! Just picture a 1 ton van towing a 3 ton trailer
up hills. I'm sure gas mileage would increase if I'm in 3rd gear going
60 mph and the torque converter was locked instead of slipping. Not to
mention the tranny running much cooler.
