925.0 transmission service level set

I'm curious in reference to MB P27.00-2450-11 that provides instructions on setting level in transmission without UT device. On the 213 model cars you set level with temp at 39 dC, on the GLS450, 166 model it is set at 59 dC. Why isn't it the same? How does model designation effect this? Tia

Also in 2022 the GLS450 is actually a 167 model. I'm going to assume setting level in it is same as 166 - 59dC?

thanks

Discussed with rep from local MB dealer and the 167 is same as the 166 when setting level.

Something I found interesting is the Sprinters that have these transmission are set at different levels based on model designation RV it is in. I wish I could sit down with the MB engineer that came up with this scheme to find out why the variability.
