I had the dealer do a trans fluid change due to slow shifting in the mornings, and its night and day. I have a 2010 GL 350 with 42k on it so it was time anyway. I recommend it for anyone over 40k the dealer charge was 460.00 but got a discount from there web site for 40.00 so not bad. I also installed the new turbo seal and pcv seals the other day the old ones were shot I did those myself when I did the fuel filter.

Yes, new atf helps shifts. That and they most likely reset your tcu adaptations lol...

Did my 07 GL450 at 100k miles, costs $475 . The stealer did charge me another $100 for replacing the pan as it was rusted.

I didn't have issues with shifting, neither before nor after. Planning on doing it again at 150k miles, if I still have the car then.
