I'm thinking of changing the transmission fluid at 14k miles. My guess is that the fluid is getting/has gotten plenty hot on numerous occasions...that plus getting rid of the break-in debris in general makes me think this would be a good thing. My dealer says $400 to do it the right way which seems to be the (fair) going rate. Any thoughts to the contrary?

i think i changed my at service A for the same reasons that you have written. never hurts just to be safe if you don't mind paying for the cost of the transmission fluid.

I changed at service A 1300 miles...felt good to do so. Like $130 more or so...

I always like to change the transmission fluid early. You are at 14,000 miles, which is perhaps a bit too early, (I'd do it around 25,000 to 30,000 miles, unless you drive the car very hard).

Going rate for a transmission fluid change at the dealer should be in the $300-$400 range. So your quote of $400 seems about right. There's a large amount of fluid (several quarts) and the fluid is costly.

The service manual says change at 40k miles.

no, this cant be right, the fluid itself cost around $16 each qt and the filter cost $30-50, let alone the labor charge, $130 for a tranny service is just too good to be ture

I apologize I was going off memory. I think it could of been about $160 or so...

point is that I changed it just to give it a fresh boost and let that cycle through after break in.

No reason not to, it can't hurt, only help. If you can swing it, especially if you really drive your car, do it.

I believe this price is for the rear diff service, not the transmission flush

^ That's what I was thinking also...our L.A. area dealers get between $400 and $600 for a trans service.

Since you have a "FEW" dyno pulls on your car, I would think that this would be a good move on your part, IMO.

ZephyrAMG

Just don't listen to a word I am saying then becuase I think I am just speaking out of my *** at this point...LOL

But I don't have LSD and the sales reciept states transmission fluid change...

I gotta go pull that paperwork out and let you know...

How can u change it yourself...on the e420

I normally try all maintenance myself with great tenacity...But elsewhere on the MB discussions I have read of a fairly involved change of fluid requiring breaking off a tube and replaing it after filling within a fairly narrow temperature range. A bit intimidating, but I have not given up the idea.

Can tranny fluid change be done by an independent shop? What kind of fluid does our tranny use?
