      Performing service on DDCT?

      Hi all-

      I've searched through the forums to the best of my ability and don't see instructions/information anywhere on how/when to service the DDCT. Has anyone done this and, if so, would it be possible to post a "How to" with pics?

      Thanks in advance!

      The chart says at 50,000 and then 100,000 for severe duty like taxi, commercial, or more than 50% driving at sustained highway speeds at temps over 90 degrees.

      There is a reservoir for fluid for the hydraulic power unit. There is no mention of a service interval for that fluid.

      A traditional concentric slave cylinder located under the gearbox casing to manage the even gear clutch and a second one located on the gearbox casing to manage the odd gear clutch. Gears are engaged and the clutches are managed by an hydraulic power unit, controlled in turn by a specific transmission control module. The hydraulic power unit is positioned directly on the gearbox.

      DRAINING, FILLING AND LEVEL CHECK

      NOTE: The fluid level in the C635 DDCT transaxle cannot be measured with a dip stick or any known probe. To verify the proper fill level. Drain the transaxle and fill with the proper amount of specified fluid.

      1.Raise the vehicle.

      2.Position a suitable drain pan under the transaxle.

      3.Remove the drain plug (2) and allow the fluid to completely drain from the transaxle.

      4.Allow the fluid to drain into the pan.

      5.Install the drain plug (2) tighten the plug to 27 N·m (20 ft. lbs.).

      6.Remove the fill rubber plug (1).

      7.Fill the transaxle with 1.66 liters (1.75 quarts) of Mopar BOT 350M gear lube (68092630AA quart).

      8.The correct fill level will be 6.5 mm (0.25 in.) below the fill plug hole (1).

      9.Install the fill plug.

      I'm curious if anyone else has done this? The manual states it is lifetime fluid, but I've seen on several threads and fora that the transmission fluid live is 50-70k miles - I'm sitting at 75k here. I've taken a few long road trips through the desert (700-800+ mile one-way) with high temps and a heavy foot - seems like it should be about time to replace the fluid (I'm not planning to address the hydraulic fluid on my own), but I'm hoping to take in the collective wisdom of those much more seasoned and smarter than I. Is this something that I should be addressing, or am I just needlessly tinkering?

      If you are concerned, replace the fluid. It looks straightforward from reading the instructions, almost like changing your engine oil. I have replaced the fluid in Neon manual transaxles and is almost the same with a drain plug bolt and and a rubber fill plug. It may be tricky to put the fluid back in, there is probably no room for a funnel. On Neons, I use one of those pump devices that is used to fill outboard motor gearcases. It just screws in where the cap was on the quart bottle.

      Thanks AGN - I had already purchased the pump, knowing it was going to be a tight fight. For anyone looking to drain and fill the DDCT transmission fluid, the drain bolt takes a 12mm hex key and there's not a lot of room to access it. Mine was frozen to the point I couldn't loosen it with the tools on hand - the 12mm hex key socket I had was too long to attach to my ratchet in tight quarters, and I couldn't loosen it up with WD-40 and box-end wrench over the hex key. I will be purchasing a stubby hex key socket (such as this one) so I can get in there with a ratchet and get some more leverage on the bolt.

      Anybody have a favorite method for loosening a frozen bolt that doesn't require an impact wrench?

      Once I finally get the job done I intend to provide an after-action report with any additional lessons learned.

      The trick is leverage. Once you get the socket, a piece of steel conduit pipe on the end of your ratchet wrench will give you a mechanical edge. I found a similar allen head drain bolt on a friends PT T-350 manual trans and it did come loose with an 18 inch pipe on the ratchet wrench.

      The trick is a Bubba. Find you a Big-O-Bubba wrench and a Thank-You-Beer.

      Alright - got this done over the weekend. There's really nothing to add to the info from @alpinegreenneon - once I got the drain bolt unfrozen (I was impressed with how well WD-40 Specialist Rust Penetranrt worked!) it was a straight forward drain and fill. You will definitely need the pump/hose to transfer the fluid into the transmission.
