ATTS (Automatic Torque Transfer System) is the system in the 5th Gen's that sends power to the rear wheels when it senses slippage.
TCS (Traction Control System) was an option on JDM 4th Gen's that uses an LSD to control slippage of the front wheels. I think it might also use brak modulation. I am not 100% sure, but other will be able to answer.
ATTS, I am sure is found only on the 5th gen SH model. But it doesnt transfer to the rear tires, as they are not all wheel drive. It just distributes it somehow between the front drive tires. (dont quote me on this info)

Active Torque Transfer System(Evens power between the FRONT wheels) Found on the SH model...
Both are junk...Buy a QUAIFE limited slip or do the TYPE R helical swap...I have been told by a SUPER racer that he fights his ATTS more than it helps him. It even malfuntions while racing because the computer can't keep up with the turning speed. Makes very loud and scary sounds, and then the ECU needs to be reset.

Traction control isn't junk. On our cars it is not that nessicary but on high power rwd cars it is very important to keep drivers that are not highly skilled from spinning out.
Originally posted by Cookout Yeah, and ATTS is defenitely not junk. It gave the SH a Car and Driver (I think) rating of the best handling car under $30K.
its junk if you are taking your lude to the extreme
i know i've read several posts sayin the ATTS sucks in autox

Where else would you go with it???..."To the Exteme, all the time every time!!!"I have to mention that this guy drives like a nut, and is #1 in the Chicagoland and TSSCC regions.
Traction control has a time and place. No time, no place for me. Maybe if I was driving a LEX or Infiniti RWD. Then it definately comes in handy...ATTS is nice for smooth sweeping turns, but anything tight and fast confuses it!!!(Hey, I like tight and fast!!!)

I always thought ATTS and an LSD where very similiar, i might be wrong of course. An LSD transfers power from the wheels that arent getting traction to the ones that are, so in a turn it would transfer the power around to get a tighter turn, ATTS i thought transfered power to the outside wheel to make it spin faster to get a tighter turn, like Nissan's HICAS. I don't know though because afterall i drive a 4th gen with neither an LSD nor ATTS.

Originally posted by Si4WS Isn't HICAS a 4WS system?
Yes, it is a form of 4WS. The HICAS senses the loss of rear end traction while cornering and tweaks the rear toe angles to keep traction. The reason many people disable it is because it creates understeer. So it isnt as much of a steering system, its just a handling aid.
