Planning to do a transmission drain-n-fill on our new to me 2012 XLE with 87K on the odo. Can you Pl. help clarify the following as there seem to be conflicting info. Looks like it has been done both ways.
- Should the initial drain be done when the fluid is cold (after sitting overnight) or should it be done with the warm/hot tranny. if latter then what should be the transmission oil tempo at which the drain plug is opened.
- While the fluid is being draining for the first time, should the engine be running or stopped.
- After filing the oil, the level is to be monitored between 108 - 113 deg F. Should the Van be running while the fluid is being drained (and temp being monitored)
