I swapped a sir II with a lsd transmission yesterday and my question is : the tranny has an aftermarket lsd, is it possible that the lsd is engaging when i am turning slowly and make a sound like clak clak clak and we feel like if the wheel where blocking ... The person who installed me the engine tells me that it is because the lsd might be very agressive, is it that ? I just want a confirmation !

What can be the cause if it's not that ? (he changed the axle (cardan) twice so it's not the problem i t I don't think it's the ''cardan'' ( I am not sure if it's the right name in english) because it do that only a slow speed and even if i turn right or left.

UPDATE, we are thinking that it might be the fault of the oil in the transmission, it's cheap 10w30 in it ... can it be that ?

And by the way, may it be dangerous in the winter ? Thanks a lot everyone

 

I'm having the same problem with my lsd

 

What type of LSD do you got ? It might help us to know it !

 

I have an oem one im pretty sure of it, i got it in a full swap and i doubt that it has an aftermarket one in there

 

Honda told me they use 10w-40 on all of their LSD trannys. Today I bought it from them for mine. Haven't installed the tranny yet.

 

I just got an 97 EK DX model and it has a b16 trans w/LSD also. I am getting the same noise from the car. It too makes the same clak, clak sound. does anyone have an idea as to what this is. I am not sure what of LSD it is.

 

Found this thread while searching.
I'm having the same problem but also a (gear) grinding noise when i let the clutch out and coast. Noise is similar to the sound when you are going in reverse. Y1 tranny OEM LSD

 

i found this post while search....


i have problem like this i buy gsr tranny whit ATS LSD and when i move the car (pushin whit hands engine off) make weird noise like clapping and the car move weird too.... its this normal for this lsd?

 

have the same problem too! i have a cable y1 tranny. somebody help!

 

I had the same problem on an h22 tranny lsd and the problem is that I belive they are clutch type and when you turn the clutches are suppose to slip but all I did was to go to the auto parts store(i went to autozone) and I bought an lsd additive I belive its called posi-trac. It comes like in a toothpaste tube and that fixed it for me. my symptoms where when you turned it made loud clunk noises until I straighted out the wheel it stoped and the car also jerked while turning. it was only like $7 for it let me know if it works. it did for me

 

yeah. i was also informed that my lsd is a clutch type. but i heard that putting in a lsd additive was bad. does anyone know what kind of oil to use? im not sure of what brand my lsd is. and i got this tranny for 200 bucks because the guy thought it was broken. i told him why it does that and still don't believe me. His lost.

 

i also read using redline mtf helps with it a bit but i haven't tried it yet.

 

did it sound like this >>>>> http://www.youtube.com/watch?v=5tSLVoGbeuk

I purchased a swap for my Ek from H-motors a few years back, and it came with a thin head gasket and an aftermarket diff. It scared the hell out of me the first time a tried to drive it. After a bunch a phone calls and research, I now use Motul FF-Comp 75w-140. The diff still makes a little noise when it's cold, and in tight turns but it works. Hope this helps

 

Sounds like clutch LSD. I picked up mine for good price, from one of the importers. Depending on the type 1/1.5/2 way it will have different characteristics. I do not forsee any winter issues, having driven 1.5way LSD in my ITR, its all about getting used to the delivery and lock up. Low speed turns and when its cold will cause chatter so do not be alarmed.

Recommended fluids I have tried:
Pennzoil Synchromesh w/ friction modifier (GM stuff works as well)
Honda MTF + small bottle of LSD friction modifier

 

i have the same exact problem.

i first used 15 50 mobil1 motor oil and it worked good for maybe a month and then it made that sound like how on the video and it irratated me. so my friend told me to put LSD additive so i did and i also changed the fluid to Honda MTF and it worked fine again. and then now its acting the same way.. WTF. anybody know how to fix this problem??

oh yeh the LSD additive was called Trans X from Napa.

 

i have a clutch type lsd also . I've had two so far and both made the noise when they were first installed. i've used cusco lsd oil and redline 75w90 with friction modifier and had good results with both.

 

I think is the wrong oil and yes lsd make bad sound

 

with clutch LSD's redline MTL and GM friction modifier normally cure the chatter. try the MTL, if you still have chatter add friction modifier until it goes away.

this is why you buy ITR gear driven factor LSD's guys j/k

 

i think but not sure could be a wrong set up of lsd. i try to explain when is installed if the lsd is to thightened on itself the intenal "clutches" may cause this bad sound...
i hope to be clear

 

when i had a kazz LSD in my civic it would make a clunking noise(at low speeds) like i had a bad axle, that was because it was very aggressive and was wanting to lock up at low speeds. when moving at anything above parking lot speeds it was just fine.

i used 75/90 gear lube with a generic LSD additive. worked for me and i never had a problem

 

it is normal for clutch-type LSD's to make a clunking sound,especially before break-in. sorry i cant quantify loud, but it is to be expected. the upside is, they kick ***.

 

I have a b16 sir2 swap and it has an ATS LSD, I too have the same problem and I am using Lucas Oil 85/140 gear oil in my trans, should I add the posi trac gear oil additive or not?, my LSD is the clutch type, thanks

 

im having the same prob with my cable j1 tranny. when i turn it clunks and feels like the axles are poping
