Im old school. CrazyGlue always rule. :P

After putting in a full bottle of Redline Fuel cleaner with a full tank of 93 two days ago, the car seems muchh smoother! I don't think I'm imagining it. The rattle is less and sometimes none at all now at idle weird... in a good way. Shifting seems smoother and so does acceleration although slight rpm delay is still there.

I doubt the Redline actually did anything with my rattle so I'm putting it to weather? It's been humid and raining past 2 days. So maybe? Lol car definitely accelerate smoother with less jerk especially at lower gears 1 to 3

hmm what is next for cheap effective care?

I just wanted to provide a follow up for anyone who cares. My car is running beautifully and I rarely notice the hesitation except when initially going WOT where I'll feel a slight lag/jerk before car flies.

Rattle appears to keep being less over time maybe the new SST fluid has gotten a chance to work into the system smoothing things out. It sometimes doesn't rattle at all all day even at idle. I can't explain how bliss those days are haha..

I have about 2 hundred miles left until my warranty kicks in and I'm going to get the timing chain replaced/looked at to see how the car performs after. If hesitation still there then probably due to clutch. Gear shifts beautifully except if i rev too hard on first or second gear and dont shift soon enough [before 4 rpm] there is slight delay b4 it grips and goes to next gear which i think is normal when hard revving sometimes as clutch tries to catch.

i should have some life left in clutch and SST appears healthy so after this timing chain ordeal, I'll probably go stage 2 unless the dealership breaks my car lol in the process.

Update September 2018: I got my serpentine belt and pulleys replaced recently after taking it to different dealership (supposedly the best Mitsubishi tech in Indiana for Ray Skillman is here lol) . The grind start up still sometimes happen. Rattle at idle still happens. I have heard about the TSB 14-22-004 reflash available that is supposed to help but multiple forums I read appears to show that it doesn't help. I am also trying the method I heard from other forums to turn knob on for 5 seconds before actually starting car. Today's the first day I am trying this... I will provide updates if it actually prevents the start up grind/jerk. It appears to be a transmission issue or programming.

The TSB 14-22-004 reflash is also noted for models before 2011 so I am not sure if that is what is causing mine since mine is 2011 Ralliart and should have the update already, but I guess I won't know until I have Mitsubishi tech checks. I am at this point thinking the rattle noise is normal, but the start up grind/jerk still concerns me. Might be a transmission issue, transmission programming, or stretched timing chain.

I also notice it sometimes jerks/lag kinda hard for a second when shifting gear up from 2 to 3. Combined with sometimes putting car in reverse takes a second longer to go into R gear, I wonder if it has to do with needing rear differential fluid change. That was the only fluid I did not change out yet through my process. I have done SST, Transfer case, and Oil changed. I wonder if that would fix some of my symptoms after the rear differential fluid change (one can hope )

Sounds similar to the sound I got when shifting into 4th I got a CEL (P183D I might be misremembering that code) bent shift fork 2, and mitsu replaced the trans under warranty. Oh and that was a Ralliart but almost identical transmissions.

I say transmission since not much else should be spinning that fast and attempting to engage or rub (so it sounds) at idle. Also be 1000 percent sure your shop knows ALL about the DCT transmission there's only one or two shops that people recommend and there's a reason.

Just my two pennies.
