I've read what I could find on the EVO X SST/DSG transmission. I pretty much understand the general concepts. However, I'm trying to figure out what happens when you pull up to a stop light? And what happens when you need to pull away from a stop light?

Is clutch engagement and disengagement simply controlled by the computer based on RPMs along with perhaps TPS and brake pedal pressure and release?

Is there a neutral? Will it start up in gear? Is there a "Park" position? What keeps the X from rolling down hill when parked in San Fransisco? Is the clutch engaged when engine is turned off?

Can someone explain the SST in detail beginning with putting the key in the ignition...

 

I know there are different modes for the sst but the basic premise is the same as the cvt so....
assuming that it is like the cvt in my lancer....

there is a park, reverse, neutral, and drive just like an automatic...
when you want to put it in manual mode you move the stick to the left while in drive, or click either paddle shifter to engage...
when stopping at a stop light it will downshift for you, i believe based on your speed...
it will be in first when you take off and you are free to shift...
when parking on a hill just throw it in park and engage your parking brake...

it's just like driving an automatic but you have the choice to shift whenever you wish...

if you would like any other details just ask....

 

The CVT is the GTS lancer and the SST in the Evo are nothing alike, not even similar. The CVT is a automatic gearbox where the SST is actually a manual gearbox.

 

No, the CVT is ... well... a CVT. And the SST is a DCT, not a manual.

 

from my understanding Its still a manual transmission, its just hydraulically actuated with 2 different clutches. kinda like the DSG found in Audis.

 

I've driven an E46 M3 with twin clutch semi-automatic. At a stop it is just like a manual in neutral. It does not creep like an automatic. When you accelerate the clutch engages just like a manual but, without you articulating the clutch. The harshness of the clutch is determined by how much gas you give it and what mode your in. It was a blast to drive the M3. I wonder if the SST is the same?

 

The E46 M3 isn't actually a dual-clutch sequential. It is a single-clutch unit.

 

There is a Park, Reverse, Neutral, & Drive -Just look at a the pic of the shift knob & its surroundings.

Also, it does shift down for you, when you slow down considerably (if it is in auto, don't know about in manual shift mode).

 

Maybe you should PM CharlesJ, 'cuz he was able to test it himself.

 

According to the April Road and Track test

In automatic mode, the systems work nearly the same and essentially mimic a good automatic — even slipping the clutches when at a stop to emulate torqueconverter "creep." When manual mode is selected, the Mitsubishi transmission does only what the driver tells it to do. It will not upshift or downshift unless instructed. The exception is if the car comes to a full or near stop, then 1st gear will be selected.

I know from reading on the VW/Audi forums that park is not a true park like an automatic transmission. A DSG car will roll in the park position so the parking brake must be used.

I drive a VW GLI turbo with DSG. From what I read so far I understood Mitsubishi did a copycat of the VW DSG system and if that is the case the car will come to a stop downshifting gears smoothly, in fact you can bearly notice it .

It has to be a speed/rpm sensor that trigers the downshifting. When you take off from a traffic light the transmission will up-shift accordingly base on pedal travel/throtle, engine rpm speed etc.

Like a couple of guys have mentioned, SST functions nearly identical (if not identical) to Audi/VW's DSG.

My suggestion is the best thing this guy could do is go test drive a VW or Audi that has DSG (Tiptronic on the Audi) and get a feel for it. Since the MR is supposed to be delayed for some unknown amount of time, testing out the DSG will at least let him know if that type of tranny is right for him.

Good luck to the OP.
