Well tonight a friend of mine did a ton of work on my GSR. I won't worry about telling you everything he did but the most important thing I figured that would be useful is the change in Tranny fluid for my Kaaz LSD. I tried the GM syncromesh friction modified tranny fluid. Before the car was loud as **** when turning, clutch plates were rubbing and it was grinding a bit going into 3rd and 4th gear when racing.

Well the conclusion. After letting the fluid take its toll after some nightly driving. The noise, the grind is ABSOLUTELY gone. I couldn't believe it. Like magic its all gone. I recommend it to anyone with an LSD....if you have any questions ask away. Im more then happy with it.

 

What does the nosie sound like? because i've been hearing some wierd nosies in my car lately.

 

Sounds like rubbing. Its the clutch plates rubbing against each other. When you turn. Im pretty sure the noise doesn't just come up, its there when you put in the LSD. You may have to check your cv joints or boots. If you have an lsd this is definately the tranny fluid I would recommend.

 

yea i hear this rubbing nosie around the clutch area but only when i am in gear and with the foot off the throttle. is that when you hear the nosie?

 

DSM trannys have been known to benefit greatly from the GM syncromesh. Didn't know that it was good to use in clutch type LSD's, thanks for the info.

 

The interesting thing was that with the oem mtf in there, it was allowing the lsd to grind and actually producing metal flakes which the magnetic drain plug picked up. I hope that, that issue will be resolved as well with this GM fluid. flaked metal is not cool !

Glad I could help ya out Pat and keep us all informed

 

ummmmmmmmmm.....i hope you didnt destroy your LSD!! those require a special fluid.....that grinding clicking you describe is the LSD GRABBING FOR TRACTION!!! it is suppose to happen that is how a clutch lsd works!!!!!!!!!!!!!!!

CHECK WITH KAAZ ASAP to make sure you haven't ruined your lsd

 

damn, that stuff is expensive, at the gmc dealership here, it was $15 a bottle. The bottles looked really old, and they said they had 5 and never sold one for 4 years. does tranny fluid expire?

btw, how many quarts does b-series tranny need?

2.2. And the kazz fluid will set you back about $90 for each fluid change.

 

I paid 9.99 per qt. Cost me about 30 bucks for the change, don't know where you guys are getting your prices from. And my bottles were brand new off the shelf, and it worked wonders.

The kazz fluid is $90. Not the GM stuff.

That's how a 1.5way (or 2way) LSD works. When your foot is off the throttle, the LSD would try to grab the outside wheel (faster spinning) and make it spin at the same rate as the inside one (slower spinning). It's more like a "defensive mechanism" for mid corner lift when lifting is necessary for racing so the car would not spin 180.

The noise is normal when you use an aggressive LSD for street use.

The Kaaz LSd is supposed to last the lifetime of the car

thats what Cheetah told me. You can find him on the Drag racing forum

If cared for as per the manufactures directions, i.e., kazz fluid only.

with all due respect I must disagree with you as I beleieve that there are other alternatives to the Kaaz fluid.

I dont have my GSR now but I was planning on putting the GM Synchromesh with friction modifier before I sold it. the current owner of my GSR says it worked like a miracle for him..., no more noise or chatter

 

cool, can't wait to fill up my tranny with that GM oil.

 

Try http://www.gmpartsdirect.com for synchromesh, part #12345349. They sell for $5.65/bottle.

And the number for the Synchrmesh with friction modifier is: #123777916. I didn't check the priceon that one though.

I fixed the link to the site above... to me! hehe!

Not sure about the syncromesh in particular, but as I recall, most GM trannies use like 70W90 or something like that for the weight of their tranny fluids, where our cars are meant to work with like 10W30.....how thick is the syncromesh??? Oil that's too thick is not a good thing...there is a reason why Honda specifies such a thin oil....

In terms of friction modifier, you want some sort of limited slip aditive, but, on the same hand, you want it designed for your application, there are many type of LSD's, Helical Gear, Clutch Type, and Viscous type as I recall, all having different requirements for fluids.....

I use Motul 5W30, and it seems to work fine for me....of course my car doesn't grind in any gears now any way.

Peec,

i used that gm fluid stuff. the stuff that i used was like a addative. works for me. no probs so far. i have a itr w/ lsd. i have to say its a lot smother than b4. just my 2 cents.!

lol, i'm not even going to comment on some of the bullshit ........ told me

a clutch type lsd might last the lifetime of the car but it will require rebuilding... lots of times.

You shouldn't have to rebuild it lots of times, if you have to rebuild it once, maybe twice with really high miles and a lot of wear, that's excesive....I guess it depends on how long you plan to keep the car, but there are plenty of ITR guys out there that are approaching 100K and havn't the need to rebuild theirs....

 

What is the GM part number for the tranny fluid?

this is true about stock lsd's, not clutch type lsd's. if i could get 100k usable life out of a clutch type diff, i would easily pay $5,000 for the diff...

If memory serves me correctly, and I'm pretty sure it does, the stock ITR limited slip differential is a clutch type differential, it is just not a 2 way or 1.5 way differential similar to a Kaaz or a Mugen, but still works the same way, and has virtually all the same components. So, if your offer still stands, I'll sell you my stock ITR diff. which is clutch type for $5,000....though somehow, I think you've probably lost interest in that offer.

In terms of any limited slip differential, over it's life, it's very possible it will need to be rebuilt, obviously depending on the nature of its use, but especially in a street car, you're not likely to have to rebuild it more than a couple times. We run the Cusco clutch type limited slip in our Civic with an ITR tranny, that we've put just under 13,000 track miles on, which if you can imagine is about 3 or 4 years of hard track time....between Sebring, Homestead Miami Speedway, Roebling Road, Road Atlanta, Moroso, and VIR, we probably have the equivalent wear and tear in those 13,000 miles that any one will ever put on their street car, and we still have not found the need to rebuild our limited slip.

Argue if you like, but either you've had very bad luck with LSD's, which given the nature of aftermarket parts, is entirely possible, or in my opinion are mistaken in your assumption.....

Laterz,
