What is the typical total cost, including parts and labor?

i replaced the fluid, bottom oil pan, bottom and side gaskets, suction and transmission filters, and all o-rings. all the parts were about $660. this was done while the transmission was out.

Time will tell for those other cars that will never see any service.

yup mine were nasty as well. the DCT transmissions definitely need to be serviced!!

I actually define "lifetime" as "warranty + 1 day".

Hahah

holy smokes, props to you for dropping trans in the garage. I've only been able to do a drain and refill.

Remember DCT is not an auto and there isn't a Tq converter - so the mechanical concept is totally different.
I'll probably do mine as preventative at 50K.

Compares favorably to this sample at 66k:

Compared to this sample at 50k even it seems to be holding up pretty well:

Another at 50k:

One at 30k with significant track time:

And one with just 2k:

Just looking at those filters though makes me think 100k is when I'm going to do all my gaskets/fluid/filters.

Thanks for the data point!

Fellow Beamers...my dealership’s quoting 3100$ for a transmission leak that my other dealership never even bothered to mention. I had my DCT replaced at 45K, so i’m guessing not everything is broken. Can you please advise if that’s a reasonable quote?

I would get a second opinion from an independent mechanic that specializes in bmws

*IF* they confirm it's *ONLY* a DCT transmission *LEAK*
It's absolutely *NOT REASONABLE* !

Where is the leak? A lot of times it's the oil pan which is an easy fix. Most dealerships nowadays are predatory when it comes to repair quotes so you will need to probe where the leak is coming from to figure out what the job entails.

Glene · 12-05-2018, 01:46 PM

I was told if you do a drain/fill, fluid will be short by 1.5 quarts. Without running the special software, how did you guys do it? I have been working on cars since 16, and it's always a pain in the a_ _ working on the BMW vehicles. Why don't they just raise the fill lug 1/2" higher so servicing the fluid won't be a headache? It seems like BMW doesn't give a damn about serviceability. If Toyota can come up with the fun driving vehicles...then who would want to purchase a used BMW?

The-Traveler · 12-05-2018, 02:03 PM

I noticed smoother operation when I changed it around 50,000KM . Lifetime my ass, don't be stupid.

So the question is to DCT owners- What is your trans fluid change interval? 37000 miles?

I got mine done at 40k kms. It does have to do a lot with how you drive and your surroundings.

Mine had the typical leak, fixed in August under Carmax warranty to the tune of $2100.
That was probably on the steep end of cost to fix but I didn't have to care. Dealership quoted me $850 just for fluid/filter change alone prior to all this taking place. Car was at 38k miles at the time of fix and I did not experience any change in DCT character after the full service was done.

Bump.

When you install the oil pan, did you use new gasket and all new bolts (14 of them)? or reused?
