it says 60°-65° minimum coolant temp for lockup to apply (engine coolant sensor). also the pcm takes into account throttle position (throttle position sensor) and engine load (map sensor). it also needs to be in 3rd gear or drive for the clutch to applyIs it normal for the converter to not lockup for the first few miles of driving? Thats all I wanna know. Does it need to warm up a bit first?

I guess you'll have to live with it. if you don't have the right tools, or money to pay someone with the right tools, you're basically SOLI know its a lockup thing, normal 55mph cruise is actually under 2500 rpm. I can tell when it goes into lockup, its almost like its going into its nonexistent overdrive.
A scanner is out of my reach, and undoubtedly my budget...
