Keep in mind that the "kickdown cable" is more than a kickdown. It controls throttle valve pressure in the trans which will affect shift timing and crispness under all throttle situations. It also boosts line pressure under heavy throttle to increase clutch and band apply pressures. Does the job that vacuum modulaters on Ford and GM did as well as the kickdown function. What speeds are your 1-2 and 2-3 shifts under light throttle pressure? If you're into high gear too soon it will cause increased temps. 190* seems high even on a hot day if no load/hills.Also, unless you have a very large trans cooler you may need the coolant to fluid heat exchange as well to bring temps down.
I'm not sure, but there may also be a corelation between your od setup and your shifting. I had early soft shifts and found my detent cable stuck (also didn't have full pedal travel). Corrected that and shifts were fine as expected, but my overdrive started working properly. Used to hunt and shuttle in and out at about 80kph under light throttle when the tv cable was stuck. After fixing the cable od does not hunt and shifts much better. I was of the opinion that the od system was seperate from the valve body/123 shift, but now I'm not too sure.
