That's according to page 312 of the owner's manual.

 

Says the same thing in the 04/05 user manual and they were both wrong too.

 

lol..

 

so it does or it doesn't at all have an LSD in any year? cuz i swear I've seen our car do both wheel burnouts? Or I could be wrong

 

If it did have an LSD, don't you think we would have seen it mentioned in even ONE Acura press release or advertisement? Not even one.

For the life of me I can't find the thread where this was discussed before, but it has come up.

 

shucks

 

I wonder how the RSX-S tranny ratios would fair in our cars? If it bolts up

 

Yup, was discussed and dismissed before. Too bad it's not true.

That thread really doesn't provide any proof that it doesn't though.

I'm pretty sure there was even another thread discussing this for 04/05's.

 

Black_6spd was thinking about putting RSX-S gears 2-5 in his TSX (not swapping the whole transmission case, just the individual gears) -- haven't seen if he ended up doing it yet or not.

You wouldn't have to replace the entire transmission anyway, you can install an aftermarket or RSX-S LSD in place of the factory diff. Pretty expensive to do though and probably not the most cost-effective mod for most of us.

 

This is easy enough to test.

-Disable VSA
-Get front tires off the ground
-Place car in 2nd or 3rd gear and let the tires spin at a decent speed
-Use a rag/towel and your hand to slow down and stop one of the tires.

If the car does not have LSD, you should be able to bring one of the tires to a stop, and the other tire will spin twice as fast as it was.

If you cannot stop one of the tires from spinning, the transaxle has a limited slip differential.

 

Yep..Black_6spd is in the process of getting this done right now!

 

I'm just hoping everything goes right. The guy working on my car has done extensive tranny work to the Grand Am TSX's and has swapped gears into RSX's countless times.

I'll pretty much have identical ratios to the 06 Civic Si.

 

Ya, sounds easy.

 

Here is the differential P/N for the 2006 TSX:
41100-RAS-000 DIFFERENTIAL

For 2006 Civic Si and JDM ITR:
41200-PNT-003 DIFFERENTIAL ASSY., HELICAL LIMITED SLIP

Since all are K-series motors and would have many shared parts, they would have the same LSD as well.

 

So can we all sue Acura now for falsely informing us that there's LSD on the car while it doesn't have? Maybe they'll replace my '04 with a '06 or '08


I bought my '04 only because I thought it has LSD

 

Actually, for that alone they should install an LSD on each of our cars. Who the hell on the assembly line confused the open differential with the LSD???

 

If our car doesn't have LSD, than why I am I still getting the hallucinations?

 

Jack one front corner of your car up on and put a jackstand underneath. Take off the wheel. Make sure you are in neutral gear with the handbrake up. Start your engine. Go look at the disc of the wheel you took off. It'll spin slowly. Open diff!

 

Let's all start a petition now

I want my LSD!

 

if a FWD car has a LSD you'd know it as soon as a wheel slips, its pretty obvious feeling

 

If you're in neutral gear, how is any force being transmitted to the free wheel (or the stationary wheel for that matter) to begin with, no matter what the diff?

Also, correct me if I'm wrong, but I thought a "limited-slip" differential was not the same as a zero-slip or "locking" differential. In that case wouldn't a small amount of slip on the free wheel be expected?

 

Unless someone else beats me to it, I'll check the differential when I put my car up on the lift for its first oil change.

 

A full lock diff will be much tougher to steer than an LSD.

Actually, on an FWD car, it might even induce premature wear on a few parts.

 

I could have sworn that the TSX that I had as a loaner had LSD...otherwise that was one slow car because now matter how hard I tired to floor that thing so I could get some wheel spin off the line, i got nothing... the only way I got like a small chirp was by droping it into neutral, reving it up to the rev limitter and droping it in drive and I got like one small not even a second, CHRIP. I thought to myself, this def has LSD, otherwise it is very slow of the line. Even when it was raining and i tried to get some wheel spin with traction off, it was like impossible.

And yes traction was off the whole time and I was running on 87 Octane.

I tried the true LSD test too by takeing a 90 degree turn at like 15-20mph and flooring it as soon as I entered the turn and I got nothing. If i did that with any other car even less powerful, i would def have gotten wheel spin from the inside wheel that is almost like off the ground..(not really but has a lot less weight on it).

Thats wierd....

 

Well, 87 octane will force the engine to have less power.... But I have squeeled the tires a bit making turns (even with the traction control?!), so I'm pretty sure my 05 doesn't have it. I'm not too upset by it -- a really good set of sticky sports car tires makes a huge difference. I don't think I can wait for these stock tires to wear out.

 

I have no idea why it did that, but it did spin. It's not a quick spin, but a slow one, about 1 revolution every 8-10 seconds. And yes, it was in neutral. If it had an LSD, the disc would have been prevented from spinning by the LSD.

 

Someone w/ a loaner - go find an empty parking lot, lock the wheel to one side and hit it. Come back w/ results

 

Last night when I removed my resonator I did a little test. If the 06 TSX doesn't have LSD, it's got a whole lot of preload on the gears inside... it definitely doesn't behave like a textbook open differential. Perhaps this is a coincidence and over time as the unit breaks in it will behave more like a true open diff.

 

You're forgetting about DBW throttle, which probably helped dampen some of the sudden throttle motion you used. And I can't believe you neutral-dropped a tranny. Don't you know that that's torture on any automatic transmission!!

And my 04 never had much trouble getting wheel spin on a wet road when launching. You must have been doing something wrong...
