Won’t use dealers service dept in town unless it’s an emergency and I have no choice. They left a bad taste when they tried to sell me European formula Mobil one for an oil change.

Now I wonder what they put in mine for the 2 free changes.
We should go together to buy the DCT fluid from gmpartsdepot to save on shipping.

Can the DCT fluid be changed by us or does the dealer have to do it to keep warranty valid?

I've always done things myself and they'd have to prove it was my negligence that caused an issue. Easy for them to say it of course.
I'd not be against doing it ourselves. I haven't really investigated the method for refill, but it doesn't seem too hard. It's all on the internets.

Keep your receipts, old filter, empty bottles and a time stamped video of yourself doing the work...

Also, be sure to clean up all those nasty oil stains off the garage floor.

A drip is a badge of honour.
A puddle is called 'evidence'.

(My utmost respect for those that have the wherewithal to work on their own cars - I watched my Father do it for years.)

I have no issues to changing the fluid myself. I only worry about screwing with the warranty.

Keep your records including the supplies purchase to prove you did it. My last DCT change I had the dealer do it because there was a bulletin stating the DCT had to initiate the "flush" procedure prior to the filter change. That was something new (may be a one time only thing) so I had this last change done with the procedure using the GM service computer etc. to protect my warranty.

Watching Rick COnti's video of his technician doing it and he is replacing a second filter that is inside the tranny. Getting at it requires the sway bar removed and the tranny jacked up. Maybe I should just tighten my bank account and get it done at Williamsons.

There's a procedure on the midengine forum by a member (2020Colorado) that looks easy enough.

I just changed my DCT oil and external filter because my 3-year time limit was coming up in 10 days. I only had to change the oil (to keep the warranty) but decided to change the filter too. My DCT oil life was at 77% left.

I bought a piece of 1/2" tygon tubing 4 feet long and put a funnel in one end and a barb fitting with 1/2" male pipe threads in the other end. I had already bought an adapter fitting for the side filler hole that was M20x1.5 male to 1/2" female pipe threads. I was able to pour the oil in the funnel quite fast because of the low viscosity of the oil.

The first thing I did was take out the oil filler plug to see how much oil was in the DCT from the factory fill. The oil started running out and it ended up being overfilled 1/2 of a liter. I then put the fittings and hose in the side oil filler plug hole and ran the hose out through the spokes on the wheel. After I drained the oil and replaced the filter, I poured 10 liters in the funnel. It was enough to fill the clear hose about a foot out from the DCT. I had a service manual, which I followed, that said to shift from forward for 45 seconds, to reverse for 45 seconds for 3 to 5 minutes with your foot on the brake. This was to fill the clutch circuits and the external filter. After that I checked the oil level and had to jack the driver's side up at an angle to drain the oil in the hose into the DCT. I removed the hose and fittings, installed the oil filler plug, and I should be good for another 3 years based on my mileage.

I bought the external filter for $121 and the 10 liters of oil cost $290. The fittings and hose were another $20, so for my required 3-year DCT oil change plus the filter that I opted to change, I spent $431."

I’m of the same thought, pick up a couple of extra shifts at work and pay someone to change the fluid.

What a farce ! Your oil is at 77% , which means 23% used and because of the 3 year mark , you had to change it!!! This is a cash grab by GM and or Dealers.

 

[Mach147]

My three year mark will come in the middle of the 24-25 winter. I sure as heck won't be doing it early, so 3.416 years it will have to be. I should have around 11k to 12k on the clock by then.

I have been following the procedure on replacing the DCT Fluid. I also picked up some more info on the Fluid Level Check Procedure Warning

Just completed the Transmission Fluid change. Removed 10 litres, 2 of those were the 2 extra litres I installed last year. The transmission was short 1.5 Litres.

 

[Roughrider]

Congrats on taking on that proceedure, I'm glad it worked out for you. You saved a lot of dough!

Hello Manofwar,
Is that the tail end of a GPZ1100 in the one photo?

Nice wing. What wing is it GM or other?

I've heard you can't get all the fluid out of it.
