Has anyone noticed that the manual transmission tc's come with limited slip diff? I am not sure if the auto's come the same way. I read the transmission fluid in the owners manual it said 75w-90. It didn't say anything about having to add limited slip additive does anyone know why? I know some LSD uses friction disk and others use gears, do ours use gears?

 

No they are open diffs, not LSD

 

The reason I ask is everytime I do a burn out from a dead stop both wheels are moving not one. I have tested this out several times. I know if you have a car that doesn't have it then if you go in reverse and then stop and go forward both wheels will lock. I can go straight down the road, stop and burnout and both wheels will lock.

 

you should try turning at 5 mph's and flooring it...

only 1 wheel spins a lot faster than the other one, therefore LSD is not equiped.

 

It shouldn't matter. If it doesn't have lsd then why does both wheels lock when you do a burnout? Just curious, I have done many burnouts in my civic and only one wheel drives.

 

the wheels aren't locking, there's just plenty of torque fed to both wheels.

 

yep, either that or you're seeing the smoke from the other wheel come under the car...:D

 

I'm not seeing smoke I am see 2 equal length burn marks

 

any pics?

 

trust me, they dont come with an LSD. otherwise scion would list it as a major selling point.

it does not have LSD

 

Yeah Scion would put that it has an LSD! It don't got one! Why would they need one? It isn't like the Tc is pushing out serious WHP numbers!

 

I see everyones point. Low rpm burnout pulls straight, high rpm burnout torque steer.

 

ok, someone want to explain to all these nubs what the diffrent is between open differential and LSD is?,Anyway, In my opinion you dont need tons of WHP to need LSD, LSD just makes a car handle tons better,

 

Yeah... I think the difference between this and the Civic is that the tC can put down some torque at launch speeds, where in a Civic you wouldn't be able to move both wheels.

 

if you are curious, put the front of the car on jack stands and with it in neutral spin one wheel by hand. My guess is the oposite wheel will turn the oposite direction.

 

The tC does not have an LSD.

For those who don't know, an LSD functions by limiting the difference in postive acceleration from one front tire to the other. Basically, one tire can only spin so much faster before the other tire is forced to spin more.

Take your tC on a long sharp corner (only if you're experience in either racing or enthused driving, keep it SAFE), and mash the gas. I light up the inside tire if I'm in third or lower. And whatever you do, as soon as you left off expect a snap of the back end. The car tends to have a dramatic oversteer once you let off the gas.

Progress is coming out with some very aggressive bars soon that will fix this problem. I have H&R suspension right now, and it definately helped.

But, LSD is going to be nice once it comes out. The reason why you're spinning both was there was more than enough force to break both tires free of traction once you slipped the clutch. Any car can do it if the conditions are right.

For those saying both tires always spin, spray water on the tire and ground on one side of the car, and leave the other side dry. That should change the results up a lil...

Hopefully that clears some things up.

 

How much would an aftermarket differential cost? Can the existing differential be removed and replaced or is there some sort of modifications that would be necessary? Is there any downside to an LSD or is it just the cost that kept it from being offered stock?

 

Tcguy is 110% right, thanks. I cant wait till an after market LSD comes out. Dont care about the cost.
