[Poll]: Should I change my transmission fluid + filter?
Car is an 08 GL550 with 25k miles.
Manual says 39k miles: https://www.mercedesbenzraleigh.com/...amg_diesel.pdf
Dealer says 70k miles...?
But neither state a time frame.

I cant find the information in my damn manual.
In the link above, it says 39kmi for a 2008 so I dunno.
Do you happen to know the recommendation for the 08?

For both 2007 and 2008 MB recommends to change transmission fluid and filter one time only at 39K, there is a note that reads "not time dependent, only mileage-interval applies". I asked MB why they recommended only one time change on 2007 and 2008, and starting on 2009 they recommends to change fluid and filter every 40K although is the same transmission, and I got no answer. I prefer to spend some money in oil and filter instead of spending a lot to repair a burnt transmission.

Happen to know fo any DIY threads or videos?
Debating on the tranny because will need to take it to the dealer.
Also because there are instances when changing the tranny fluid has caused problems because the transmission becomes "used to" the old oil. Although I feel like my tranny's fluid should be ok to change due to the low miles.
