how do i know if my car has it or not

 

If you have a USDM tranny from any year it probably doesnt have LSD...The only tranny in USDM is the TYPE R tranny...but if you have a JDM tranny...there are some that have LSD...i am not too sure...correct me if im wrong

 

what are the benefits to having lsd, transmissions are smomething i never got into and know little to nothing about.

also is positraction stock to the si hatch back....just another random one to throw out there, cuz i just noticed tonight i leave 2 skid marks when burning out not one.

 

i have a car that used to have a nice swap, something happened and they put a sohc in to get it moving and sold, all suspension work axles etc are still there from the last engine. so i didnt know if the positraction was stock or something left behind from the last engine.

fron end was chopped for intercooler oil guage still under the hood and theres evidence of there once being a tack and pillar guage.... thats why i asked so i could know if it was installed or pre existant

 

you don't have LSD

 

Positraction huh?

Not unless someone retrofitted a Chevrolet LSD in that thing.

What engine and tranny are in the car?

You can leave two solid black marks with open diffs easily.

Positraction is another name for a Limited Slip Differential

if it still has the axles from the other engine, then i was a sohc, being that they are not interchangable with the any honda DOHC.

with that being said, the true way to tell if you have LSD is to take the axles out. with the axles being out, look through the tranny where the axle will normally be. if there is a bar going through, then no lsd. if you can see clearly through it then consider youself luck, you have LSD.

but unless a aftermarket LSD was installed (which i'm not sure there is one for the D-series), you do not have it.

That doesn't tell you anything. You can easily do that with an open diff.

"Positraction" was actually a Chevrolet-specific brand name for the GM limited-slip diff, which unfortunately became a genericized trademark (like Coke or Kleenex) - which is why Mr Hammond posted what he did.

Um, no, you shouldn't. Especially not with a diff as mild as the OEM Honda helical piece.

There are a few aftermarket limited slip diffs available for the D-series trans.

2006 is the first year that the USDM "Si" had a Torsen axle.

"Positraction" is a GM trademark for a clutch equipped LSD.

Honda LSD are usually Torsen axles, gear driven. In the JDM, there are a very few GS-R and other cars with fluid driven LSD.

I do not think Honda ever had a clutch LSD.

 

Thank you.

I never said that it wasn't. I'm pointing out that it is the same conceptional design. Hence the link to howstuffworks instead of a historical wikipedia page.

Every single one listed there are the same conceptual designs. They are just "marketing" names for the same thing. They are ALL Limited Slip differentials.

The poster asked if Si hatches came with "Positraction". Well seeing as how the transmissions in those cars were not sourced from a Chevrolet Parts bin, then they obviously do not have a Chevrolet LSD in them.

are you trying to prove me wrong or something? This is stupid. I realize what he asked and I realized what you said. Your reply serves no value here.

OP: does my civic come with a posi traction
YOU: There's no way that you can get a chevy unit in your honda

ME: to the OP, you're getting confused with the term positraction, it's really just a different name for an LSD.

everything else: blah blah blah blah blah blah blah

The only d-series LSD's are the DOHC JDM Cable ZC transmission which requires hybrid axles to be fitted in any hydro chassis. Check out EYAL's thread where he's attempting to put a cable ZC LSD in his hydro trans, he's running into all sorts of axle issues:
https://honda-tech.com/zerothread/1784549

The only other OEM D-series LSD's are the overseas jdm d15b with the factory option of the "Viscous 1 way LSD" and the hydro zc lsd transmission, which is IDENTICAL to the jdm d15b LSD transmission.

Every person I know with one of these OEM D-series LSD's had to struggle to find one because they're that rare.

The OP would be very aware if his car had an LSD D transmission, because they never were available stateside, plus the OEM d-series LSD transmissions are very hard to come across.

The torque will take the path of least resistence if that path is offered. You must just have been lucky enough that you were pointed very straight ahead and not enough weight difference left/right to give the torque the tendency to want to go to one wheel.

With more HP or a different set of circumstances, you might not be so lucky.

Well technically you made that replay to me in saying Positraction is another name for LSD.

I wasn't trying to prove you wrong, just add to what you were saying as it wasn't complete. Positraction is not a "general" name for LSD, it was a word the Chevrolet division of General Motors made up as a marketing ploy for vehicle equipped with an LSD. I was merely just letting everyone know that.

Of course I know what he's talking about. If I didn't, I would not have replied. I was merely letting him know the truth. I'm not nitpicking at all. Nitpicking, to me at least, would be correct the word use of "motor" for "engine" when talking about a combustion type. I just accept it and move on.

I'm not trying to argue or correct anyone, as there were really no falsities stated.
