I could almost promise it's the mount. Personally I sort of like the fact that I can hear the gears and every time a solenoid flips.I'm in the same boat, I know know the Manual says its lifetime, but my DCT at 52k~ miles started to make a strange clicking sound when slowing down. I can't determine if its the solid engine mount I installed, or the DCT. There is a guide on the Forums, but just looking for some input. I'm going to be checking my mount tomorrow. Literally was about to post a thread about this, not to piggy back. This is good info. Thank you.
From what i've been seeing it is a "suitable replacement for the OEM fluid Kia API GL-4 SAE 75W-85, fill for-life" but its hard to find any site that directly states its DTC fluid.good to hear is redline dtcf recommended ill have to look around.
