Or at least explain what it likely does? Thanks!

Well the transmission changes shift pressure with temperature and senses load from TPS voltage....both sensors feed the TCU so you could play around with voltages from sensors to TCU via placing resistor in series with leads.....or parallel and isolated.
Assuming the chips in TCU/ecu don't sense something is wrong you might get firmer shifts if adding more pressure will accomplish this.........?????????????????
Hard to add voltage to TPS without it looping back to ecu but the thermistor in the transmission is standalone.
Whether the harder shifts from the transmission thinking the ATF is not warmed up will create MORE or Less wear is unknown....if you fool it too much it won't shift to 4th gear or lock up the TC.
The TCU signals the AT to shift at the predesigned rate but it isn't the TCU fault if the mechanical aspects of the transmission can't keep up.
transmission will easily last 180k if maintained from brand new nothing much made can compesate for mechanical wear.......maybe a real thicker ATF [Redline high temp] but there are downsides to that even in Summer [impossible in winter].
