Hey. Guys, I got some problem on Twin Clutch SST.
These days in winter time, when I press harder the acceleration in order to pass other car and it shifts down, but will not
Resume to higher gearing so that speed lowers rather than speeds up. (It will not shift up) This problem put my life in danger twice
on the US295 Highway (In NJ) because I had to pull my car over to the shoulder side with slowed speed of down shifted gear.
You guys any info for this problem?
my car? 2009 Ralliart.

 

Will it not shift even if you try and shift up manually? This has happened to a few people where it would be unable to shift into all the even #'d gears. I believe it was the MAF sensor going bad that caused the problem.

+1 take it to the dealer asap and get ur maf sensor checked out..thats what i been hearing 4rm every1 who has had with there sst so far

 

It's very hard to understand your grammar. Are you saying that you stepped on the gas pedal hard, the car downshifted a gear and you passed a car. Then, the car wouldn't up shift after passing the car?

If it is in sport mode - AUTO the up shift will only happen at the next redline.
If your in normal mode - AUTO, there could be a problem.
Are you referring speed as RPM's?

 

idk how this is associated with the MAF had the same problem, NEW trans was the answer, Had the new trans in for 10,000 miles now no problems as of yet. U can ask about thew MAF but I believe theres several of us that had the tranny replaced not the MAF. What mileage u at? Mine went at around 18,000.

 

what needs to be replaced all depends on which codes were set at the time of failure and the complete diagnosis results. good thing theres a warranty!

 

Really appriciate your answers.... it is under diagnosis procedure now... hopply will be fix it.
thanks again.
