LSD for VG?
Hi Guys,
Is it possible to add a LSD to a VG auto tranny? Are there other Nissan LSDs that would work, like the one from the VE auto tranny? Or are there aftermarket ones?
If not, then is the VE 5spd swap w/VLSD the only alternative? Thanks.

I'm not sure about the VG transmission, but so far, what i hear about the VE transmission, is that you can swap the LSD from a 4th gen transmission (it is geared, instead of viscosity based, thus more power to the ground through both wheels 100% of the time)....so i'm guessing that there is a slight change oe being able to do it, but being that its probably a different design, it seems doubtful. good luck!
edit: fixed.....it was the 4th gen, not the 5th or 6th

I assume you are referring to the VE 5spd tranny that already comes with VLSD.
My situation is that I have a VG engine with an Auto tranny and was trying to figure out if there is any way to add a LSD to my existing tranny or if I have to swap to a SE 5spdLSD.

If that is the case then I will definitely consider it, but I seem to recall that Matt93SE and other knowledgeable senior members said that a VG auto to VE auto swap is not possible. I'm not sure why, considering that a VE5 will swap onto a VG auto or manual. It seems to me that the trannies for the VE5 and VEauto should have the same bolt pattern. Anyone care to enlighten me?

what i meant was the ve-5 swaps into a vg, with just a few additional part swapping.
I was under the impression the ve-auto was vlsd, and would swap in a similar manner.
is any of this inaccurate? we need to fix my understanding now before i fubar somebodys car with my advice

We heard before how the starter is in the wrong position on the VE auto compared to the VG auto. I wonder why the VE5 fits then? It must have the starter in the same place as the VG auto. If that's the case, how is it that some people swap from a VE auto to a VE5spd?

Not purposely thread jacking, instead spinning off of the topic...
How difficult is it, theoretically or reality, to swap the VE5 into a VG? I'm interested in doing this, but I was wondering is it something I can do in my little garage, and how long it would take an experienced DIY'r to do this (it take me 2.5 times longer than a experienced DIY'r to do something I've never done before )

anywho...
okay i just checked my engine bay. there is too much stuff that would need to modified to make this remotely practical.
can you swap the case halves to accommodate the starter? will the VG engine side mate with the VE gear side, allowing the starter to remain in the stock place?

The VG and VE autos are so vastly different its like hmm they are completely different trannies maybe? Not even close.
The main reason you cant swap a VE-A in is the flexplate problems, and the starter doesn't like up relative to the flexplate. How ever, the VE-A tranny (probably VLSD-less) is suppose to be used in the quest/villgar and maybe windstar so it should have the proper flexplate.
Then theres the electrical issues. Enjoy swapping all the nessicary tranny computer and wiring. And the ecu/tcu might be interdependent but I;m not sure.
Thats about it. Its alot of work to do it but hey its your car. I hope its worth a possibly worn out VLSD.

IIRC the VE auto trans number still ends with a "V" for VLSD

correct and half the reason why youd want to do it. The other half being a stronger tranny.
Read what I said as: the Quest/villigar/windstar transmission probably doesn't have VLSD so I wouldn't take on of those out of the junkyard. I didn't mean the VE auto doesn't have VLSD.

windstar = crappy AXOD-E
you may be able to swap the VLSD from a VE into it though

Is there a conclusion in here somewhere??? I have an interest in doing this LSD mod
too-- IF, (and it's a BIG if), it will work. Does ANYBODY know for sure? Or are we all guessing and tossing around heresay? After climbing under and over both VG and
VE models, it does not look to me like the bolt pattern is the same-- aside from the
different starter location. Has anyone done a side-by-side comparison of the bolt
patterns for thesetransmission or compared the differentials OUT OF the transmissions?
About two years ago, I remember seeing an article in Import Tuner I believe it was, describing a company that made a device that you bolted into the dif housing on one of the spider gear shafts. It looked like a 2-piece block of steel sitting down inside the dif. The two pieces had a cylindrical-shaped hole cut through the center, and I think there were some flat metal links that tied the two blocks together on each side...The design was supposed to bind up the dif if one axle began spinning
above a certain percentage faster than the other. I called the company, and spoke to one of their tech reps, who told me if you could provide them the dimensions of
the space between your spider gears in the dif, they could machine and adapt an
existing unit to the Maxima dif. I asked several mechanics at transmission shops about this device. None of them had any idea how it was supposed to work, or if it was reliable. They had never heard of such a thing. I am a blank on the name of the company. Anyone else hear about this?

that it?
its a differential locker, the one shown is by powertrax.
i dont know if it would work or not, (provided it CAN be "modified to fit"), because the cases don't seem to have enough space (i am comparing the cases of the ve and vg tranny exteriors, never doug into either.)
sorry about the link, couldnt use just use the pic...

The device on the Summit Racing link is NOT the one I saw. It was literally-- like a squarish block that was split down the middle; not round.
MyGreenMax: Are you saying the Quaife unit fits the VG automatic? Has anyone
tried this? OR.. Can it be machined to fit?
Curious minds really want to know!

and the side of the trani being blown out from a hard shift. LOL (I know--
I've done that a couple of times; but not with my Maxima.)-- If a AT is "slipping" or making a loud "clunk" when shifting from reverse to drive or back again, you're really only talking about normal wear of the trans brake and clutch disc abrasive material. The usual AT rebuild type repair. More often than not, trans cooling is a neglected aspect of maintenance and can lead to premature failure-- especially if there's a lot of heavy hauling, towing or mountain roads are a regular happening. I had over 200K miles on mine before these symptoms began to show up...

Well there is a difference between worn clutch steels and clutch discs
