The proper fill level for the 7AT transmission fluid is based on the volume of fluid at a specific temperature. The temperature of the fluid affects the volume since it expands as it heats up. There is not an easy way to get a trans fluid temp readout without the CONSULT-III machine hooked up to the car. It can cause issues if overfilled or underfilled so it's best to have a good idea of the fluid temp when doing a flush.

If ECUTek would get off their butt about updating the PID's we could see it on our ECUTek screen via gauge or datalogging. Supposedly been in the works for years.

For now I scan the trans pan and aftermarket cooler (OE cooler deleted) entry with a infrared temp. gun and average the 2.
