Does it have traction control? (ATTS)

ATTS is NOT traction control... Although I can see why you might think so...

It is a Torque-transfer system...
Traction control uses brake pulses to modulate the wheels, so that they do not slip...

ATTS only transfers the torque to the outside wheel in a turn, making that wheel on the outside rotate faster than the wheel on the inside of the turn. This is in order to induce yaw movements into the car, and make the car exhibit oversteer, even though it is a FWD car and FWD cars always have understeer problems.
Think of how a wheel-chair operates...

Now for the SH part...
All the ludes from 97 up come with the H22A... Although there is slight differences in the engine construction between 97-98 and 99 & up models.
If it is automatic, then it is definitely NOT an SH... SH comes only with 5-speed
SH models have straight spoke 5 star wheels (not the twisted star pattern)
Come with the spoiler
Has a different shift knob
leather steering wheel
And of course the ATTS

ATTS is not/does not help you gain traction. It only helps to introduce non-fwd dynamics into a fwd car...

Look at your VIN to see if it is a true SH??????

There are other minor details, like the shifter knob is different etc.

Do you have ATTS? when you turn on the car does the ATTS light blink on & off?

i looked up the vin, CARFAXED it but doesnt say type SH, just says coupe. And the ATTS light doesnt blink, so im fairly sure i dont have a type sh, and i have the side skirts that dont match the car so i think its the base model... i THINK, once again as usual i could be terribly wrong about this

check your tranny code. M2Y4 is the base model tranny and M2U4 is the SH tranny
