I bought mine new and have just over 60K miles and no issues. I serviced the SST @ 45k with FFL-2 fluid and factory filter. My mods are only the GST map, boost pill, and Evo X BOV. I do 90% hwy driving, so I'm usually keep it in manual/normal.

 

2012, 15k miles, abused A LOT since 10k. 370WHP, some track days, a lot of launchs done, no issues at all. Let's see how its gonna handle when time goes by.

 

85K just now starting to slip but that because of the fp red, 70k with the stock turbo. Ran 12.2
With slipping clutch. Can't complain I have drag racing this car since it had 3k http://
The first day the car got tuned I got second place at a bracket race

 

Nice Nice . Keep the replies coming

 

2011 RA / 51,000k mi. Mods include Evo X IC & BOV, GST boost-pill & base maps, and DIY short ram intake. Never been to the track, however i do drive spiritly at times. This is my DD so I need this car to last. Most of the time I'm on the highway in normal auto/manual mode.

I've gotten the occasional 1st gear slippage that some have claimed while coming off the line. Once in a while, when decelerating on normal auto, I get a really loud knock and jerk when the tranny downshifts hard from 3rd to 2nd. I have no idea what is causing this so if anyone can shed some light on it, I'd appreciate it.

I've never flushed the SST yet, but I just ordered the fluid and filter and will change at 60k as suggested in the service manual. Although others have suggested changing it sooner, I'm mostly cruising on the highway at 6th so I'm in no rush changing the fluid. Although, I'm hoping these issues that pop up from time to time would resolve after I flush the tranny.

Other than the occasional hiccups, no major issues to report.

 

Do not wait til 60k! Change it now! u should have done the change 20K mile ago

 

Yeah I agree you should do it every 30k. Stop and go commuting would put you into the severe conditions intervals, not normal. unless your always smooth sailing to work everyday.. in that case LUCKY!

 

99600 miles slight slippage in sport. In normal it slips period. It will need the clutches upgraded this year or next.

 

Just thought I'd give a bit of an update on my now almost 104k (Km's) tranny. Just changed my fluid and filter and where there was slight slipping before, it now shifts really crisp. Even normal mode has a healthy snap that wasn't there before.

 

Just did my fluid today, at 75,000km. Previously done at 45,000km.

Shifts beautifully...

Did you use the OEM Diaqueen or another brand ? I am surprised it was clean and did not look like sludge haha. You must be much kinder to your car than most of us lol

 

67,000 Miles, DD/Autocross. 285whp/310wtq Mustang Dyno. Changed fluid every 10,xxx Miles on the dot with OEM fluid. Clutches went out at 67,000 miles and is currently being rebuilt and upgraded to 600hp specs by jack's trans. Only launched a very few times.... Going big MAP EF-3 as well.

 

Seems to be a trend with the 2009-2010 RA guys. Each time I see someone who has their clutches go out it is usually someone who had a car from this year. Makes me wonder what Mitsubishi changed for the newer models.

I know a few people who their stock clutches lasted longer than 67k and they abuse the hell out of their car. Has to be a quality issue with the older models for sure.

 

Most likely, the '09-10 model years definitely have their issues, especially cause the TC-SST was Getrag's first Twin-Clutch unit, i believe. I think it has something to do with the way the SST is mapped out, the clutches tend to have more slip in them compared to the newer years. Glad i did the upgrade as a whole package though, though it is expensive- the SST is a good trans.

 

I wonder if the majority 09-10 that had transmission issues were caused my how the cars were tuned, I remember watching 2 different 09 ralliarts get tuned and the clutches didn't long
