2015 Subaru Crosstrek CVT
I'm going to drain the fluid from the pan and then add approximately 4 quartz of fluid until it reaches the fill hole. Once the transmission temp gets between 95 and 113F, I'm going to shift from Park to Drive and then back to Park, and then add approximately 1.5 quarts until the fluid comes out of the fill hole.
When I add the new fluid it's going to get mixed with the fluid that has expanded due to the raised temperature. Once that new fluid expands, the level will rise well over the fill hole, which will make it overfilled. The fluid can't drain out by the time it expands because there will be a filler plug in place.
Now let's say I loosened the fill plug the very next day while the transmission fluid temp was between 95 and 113F. Fluid would most certainly leak from the filler hole because the 1.5 quarts that was added had not yet expanded during the drain and fill process.
The service manual for "Adjustment" says that the correct amount of fluid should be at the lower level of the filler plug when checked between 95 and 113F.
What gives? The "Drain and Fill" process and the "Adjustment" process would cause different amounts of fluid in the transmission.
Am I making any sense in my thinking?
