Hi Folks:

I'm looking to do my own DCT Fluid and Cannister Filter replacement - yes, i like to do these things myself.

Calling around, i am blown away by the price of the AC Delco FFL-4 fluid - it is 50% more than i paid at this dealer in mid 2024, and the filter is >$300. I know most people have the dealer service their cars, but for those that have done it themselves, was wondering where you purchased these items?

I have seen rockauto.ca has a good price, but is that shipped from a Canadian warehouse, or out of the States? Obviously don't want to get hit with a major tarriff/brokerage fee.

Anywhere else you can suggest i look for a "better" price? Ideally shipping from Canada.

Cheers,

Rob
 
I got a filter from Tubman in Ottawa in Nov. of 24.

Cost with freight and tax was $205.00. Part # 24045729.

I keep it as a spare as sometimes the dealer may not have one in stock.

I wouldn't do the filter change myself because I have no way of controlling the TX to circulate the fluid through the TX which is apparently required with a filter or fluid change.

You need to get a look at a service manual to see what the process is.

After writing this I see you responded in the sticky at the top of this page about filter change requirements.

Looks like you may have already done one on your car.......carry on.

Did a filter and trans oil “flush” and fill myself and documented on iPad video. Bought the filter and trans fluid from Tubman GM parts and a Foxwell OBDII reader online that accomplishes the flush procedure. All in wasn’t $800.00. And I still have the Foxwell reader that does a variety of GM vehicles. Warranty can’t be denied if the work was done properly ( hence the video for proof).

Here's a copy/paste from my post from April, 2025;

For anyone planning to do a filter change, I've been searching for a good deal for a genuine GM filter, part 24045729.
Best I see in Ontario is True North Chev, a GM dealer in North bay, ON. $155.12 thru Parts dept, but they also sell on eBay,
Genuine GM Automatic Transmission Fluid Filter Kit 24045729 | eBay (https://www.ebay.ca/itm/405131694468) for $124.39 cad plus $4 shipping.

~$40 seems to be the going "good" price for 19418016 fluid from a few sources.

You'll need 2 Torx pattern sockets, E8 and E16 as well as 10mm and 13mm 6 point, cordless driver/ratchet, and extension.
 
That is a very good idea to take a video of the flush procedure! Which Foxwell reader did you use? 510, or 710?Amazon does not seem to have either for Chevrolet, so buy from Foxwell direct?

I have bought many auto parts from rockauto. They do ship from the states. They also charge you shipping and taxes. It will be an all in price. There will not be anymore taxes or duties when you receive your parts, fluid etc.
 
Has any one seen this about servicing the DCT. It seems like GM has changed the proceedure.
In the title of the thread, Hydraulic System Flush. It is procedure that for several years was step 1 in the procedure for changing the external canister transmission fluid filter. It was deleted from the procedure recently, but was added as the last step in the procedure for changing the transmission flied. Both the filter change and fluid change are routine maintenance procedures called out by the Owner's Manual.

It is described this way in the Service Manual: "This teste executes a procedure in the TCM software to actuate the solenoids in a specific manner to flush debris from the system". In addition to being part of routine maintenance procedures as noted above, it is also sometimes a possible step in a diagnostic procedure for an actual transmission issue, and has been know to resolve issue.
 
One of GM's Corvette engineers has stated that it is something that happens in normal driving so it can be eliminated. It's just a "might as well do it" if it's in the shop kind of thing.
I can't see why it would ever be the last step. Perhaps it's just meant as a footnote.

I think they said that a spirited run for twenty minutes or so just before putting it up on the hoist is adequate. And yes you would think using the hydraulic flush would be first logically.
 
Tremec shows the fluid to be used is FUCHS Titan EG FFL-4 in the TR 9080 DCT.
The EG is German that stands for "first gear oil" or Original Equipment.

Fuchs has indicated that Titan FFL-4 is the same.

On the above, see that it says "Formerly Pentosin FFL-4" since Fuchs bought them out.
I get it from FCP Euro.

Titan FFL-4 Dual Clutch Transmission Fluid (1 Liter) - FUCHS 602007209

For the canister filter, Rock Auto carries the OEM version for ~$99 USD.

By the way, FFL means "First Fluid Lubricant". Pentosin FFL-4, currently branded under Fuchs TITAN or AC Delco is a specialized synthetic fluid developed for high-performance wet-clutch dual-clutch transmissions (DCTs) that often incorporate limited-slip differentials (LSD) in a transaxle configuration.
