Why not?

Say you're in EV-Mode.
You have
Power flow MG1
Power flow MG2
Trans-axle losses
Combined those are your heat sources to deviate from ambient.

The source of MG1+MG2 heat contribution is their power flow and their efficiency map... which as I recall that motor efficiency map has been done.

If you quantify the contribution from MG1 + MG2 what dT is left is from the trans-axle itself.
