i just completed installation of 3.8 SC series II 97 grand prix gtx motor and tran into 87 pontiac fiero. the shift points are two high in regards to horse power weight ratio. would love to drop over drive to engage at 35 mph rather than 45 mph. there is plenty of power to support the lowering of shift point. I may swap ground signal between lock up and odrive first and see how that works. any sugestions
