how can you tell if your trans is LSD, heres why om asking i had a new trans put in at 50k miles and i think they didnt get the LSD trans, it seems as if it spining one wheel only.

 

I saw a pic somewhere that it is marked on the transmission nameplate if it is an LSD model. Not sure where that plate is though!

 

G85, youll know if its an open diff or not, a Quaife would not have its inside wheel spinning like crazy

 

mines supose to be a LSD but this dealer is shaddy and i never go there, i swear they put the wrong trans in, ive seen this tag there talking about but whats the code say when its an LSD?

 

There is a plate on top of the transmission that designates it, but I'm not sure what it says. It's hard to see.

 

check your bill.. it should specify LSD with a part number. other than that don't know.

 

i think i might as well take it in to my good dealer and ask them to check it.

 

yep then call GM canada and have that dealers pee pee slapped if it's not an LSD

 

Jack up the front until the tires leave the ground

Start spinning one of the front wheels

If the other wheel start to spin in the same direction, you have LSD

If the other wheel start to spin in the opposite direction, you don't have LSD

 

lift the carpet in the trunk, there is a sticker with all the codes, if u see g85 u got lsd

 

his dealer replaced the transmission and he is unsure whether the new trans has LSD

 

thanks i know it has it. you should read more. lol. thanks tho

 

if i ever get time to ill try that. so busy at work and trying to get a house. ill be pissed if it is not an LSD . plus i got like 10k miles on since and just have now knoticed this since its rained alot.

 

oh lol i didnt read the whole thread

 

I don't know if this is correct. I think that's an old-school rear-wheel drive, LSD rearend, test.

 

It has the L on it. I took one apart with the L on it and it was a LSD. Some have LSD on the tag also

 

Limited slip diffs dont usually allow both wheels to rotate. Pretty sure thats a full locker.
You would have to overspin one of the wheels to activate the LSD weights.

As for the cobalt LSD in particular, get the part number of the transmission on your repair bill, call your dealer and ask which transmission it is. The parts catalog at gm will tell you, if it doesnt then oh well, i dunno.

 

i wish i knew what i did with the repair order

 

any dealer should be able to access the work order...
the replacement parts should be listed too...

 

i got a plan for this weekend. since parents are gone. im going to light up the tires and see if i got 2 trails.

 

BWAHAHAHAHAAA!!!! I forget how old I am. I guess I'm old enough to be your Dad.

 

Well, the only problem with that plan is that it won't prove anything unless you're going around a corner. My car doesn't have an LSD and it smokes both tires from a standing start. LSD only affects when you're turning. If you want to try to road test it hit a tight low speed curve and then punch it. If it roasts the inside tire you probably don't have an LSD equipped.

 

If you really want to be certain. its really very easy to see you just have to shine a light between the fuse box and the head down onto the top of the trans. you will see the top of the trans with the black plate with number. if they replaced it with a turbo charged cobalt trans with 3.82final drive, if it says 55564936 its an lsd transmission. if it has the numbers 55564935 you dont have an lsd.

 

thanks man. i plan on looking at that today, since its in garage and not in the rain out side.

as for the turns i do that alot and even my old taurus never broke a tire loose.

 

if your 50 maby. since i still live at home i got to follow there rules, have been trying to move out.
