I have had this tranny for awhile, never been installed after the rebuild.

The rebuild was also to include a conversion to a LSD. So just to make sure I thought I would spin one side thinking that the other side should rotate in the same direction. Wrong . . it turned the opposite direction just like an open differential would. In a panic I took the cover off just to make sure and here is what I found.

An LSD

it could be a very worn out lsd?

Here are the facts;
1. rebuilt in 2009, shipped to me with no fluid and been in storage ever since.
2. when Trans shop received the Tranny it was suppose to be a LSD and the plan was to rebuild everything up to and beyond stock.

3. Since the tranny did not have an LSD I purchased a used unit for IIRC 500$ sent it to the shop and paid also to have it rebuilt.

Bottom Line: I have no way in my garage to test the unit however I do know it is missing several several parts that are included in the install, that you need. Key thing here is will it function as it should or am I wasting my time.

MY tranny in the car does not leak at all and shifts good

i don't have one, but i thought the pump is what applies the opposing torque?? so I assume when dry it won't do much. not to mention all the sensors and whatnot you need.

See posts 3 and 26, I think you could test the unit as described, no?

Is this just a diff unit or is it attached to the rest of the tranny?

Waste of time. A fresh limited slip should take a minimum of 20 ft. lbs. to overcome the friction discs....not something you should be able to turn by hand.

Pretty much everything you need to know, in that thread that Edwards referenced.

Choked me up to see that post from Greg Nettles. I guess that is the definition of immortality.....missing you buddies that are gone. What a great guy!

I had the same issue. Thought a trans did not have LSD, when in fact it did--it was just really worn. Before I took the back cover off, I discovered it had the limited slip once I had less of a mechanical advantage when turning the output flanges versus the entire wheel/tire.

I have an early 8-disk LSD I should probably sell if anyone checking this out is looking for one. I have disassembled it (all internal parts are zip-tied together, in order) for a rebuild. Paid $600, I'll take $485 + shipping. PM me if interested.

Where were you 6 months ago when i needed one, and before I paid $700!

That won't last long at that price. Screaming deal.

Benton

Sorry for the thread hijack...

Yeah, it may be a bit low but I need the cash soon for next semester's tuition and I figured it deserved a low price since it is disassembled. All of the parts are there and in order.

It's sometimes hard for me to look at the older threads when I see his posts. Hardly a day goes by where I don't miss having him around.

Easy to test with the LSD in the case if you have two torque wrenches - put one on the bolt on either side.

You had it in gear then rotated one wheel?? (if that is an entire transmission)
if so, when one side is rotated, the other will rotate the other direction, even with LSD and a good one, AND by hand.

But,
out of gear (neutral), hold one side and rotate the other and there should be between 15 and 20ft-lbs of resistance. ( make sure its in neutral, as rotating one side , while holding the other wont have the same effect as if the transmission is in gear).

Thanks Rob for the Link.

Mark,
It is an entire transmission and it was out of gear (neutral).

I am sending you a pm

Thanks to all

But, it was on the bench and not tied to a torque tube, or clutch plate pressing on an engine, locking it in place. If you hold the input shaft coupler in place and then turn one side, you might see both sides spin the same direction.
Just curious to see if that matters. Ill try it tonight on my transmission in the side yard!
