Because I just purchased my 2007 MB ML350 4Matic, I always like all my fluids to be changed and fresh.

Recommendations for tranny fluid change? Is it a big deal to change the tranny filer too? Should I? Car has 149K on the clock. Shifting is barely perceptible. Just about flawless I’d say both up and down shifting. Or should I just leave things alone?

Same for oil change. I’m thinking LubriMoly oil and OEM oil filter. Right now oil looks good. Looking at the timing chain via the oil cap, it’s crazy clean in there.

Any other suggestions too regarding gearbox/transfer case, rear end etc?

Thanks everyone!
