Default Limited Slip Diff ?

I have a '90 L98 auto. and I plan on having some fluids changed next week. I know that you have to add additives to limited slip differentials but how do I know if I have a limited slip diff ? Any help will be appreciated so I don't look totally stupid when I talk to my mechanic.

all vette rears are LSD.

You need an additive from the GM dealer. Thats the best bet...

Just jumping in here as this answers a question I was wondering re LSD.

I thought all C4's had a LSD as standard but I was reversing up a steep tiled driveway and it seemed one of my wheels started to slip.

I didn't want to leave a big black mark on my friends brand new million dollar drive way so I couldn't experiment.

Yesterday I floored it on a loose foadsurface and it seemed that both wheels spun - I'm a bit confused - any more info anyone please ?

(Hope it's allright to jump onto this post)

My understanding to LSD is that the slip is limited. Meaning that even when backing up on your friend's driveway you would have left a mark but the other tire would still have enough power to pull you up.

A locked diff is what i used to have on my 1978 CJ-7. Both tires would always spin.

A regular diff would have left a black mark on your friend's driveway but the car would have a very hard time getting up.

Here is a small trick I learnt driving in the snow. When you are stuck in the snow or ice and only one tire is spinning. You should apply the brakes just enough to stop that tire from spinning and in doing so you will give some power to the other tire. :cheers:

The real trick is to only apply the REAR brakes to stop the one wheel from spinning. Use the emergency/parking brake to accomplish this....

Yes that is true on a reae wheel drive. Most winter drivers are front wheel drive so putting the hand brake on is pretty much useless.
