It has nothing to do with your trans, so no it won't affect your trans software.

What the reset does is ensure the potentiometers in the gas pedal are matched to the return potentiometers in the throttle valve. If the DME doesn't like what it sees it goes into fail safe mode and limits the RPM to something like 1300 rpm.

These potentiometers are use in concert with the MAF to cross check eachother.
