pmohr: sorry havn't been on in awhile. I found the trans on car-part.com and put it in the weekend I got it - It works great and feels good, however it is NOT an HLSD trans. I need to bring my original back to the place I got it to get my core charge back and will discuss what they can do to compensate for not providing a unit that was sold to me as being a locking diff(HLSD) trans..when it actually non-locking. {jacked up car, spin one wheel and the other wheel spins the opposite direction -- Also, accelerate out of a right-hand turn and it does a one-tire-fire....}

 

That's a good test for VLSD or clutch-type mechanical LSD's. A torque biasing unit like a Quaife or 6-speed HLSD is not effective when one wheel has a complete loss of traction and will act like an open diff during that condition, aka your test.

 

That would be shorter gears, not taller.

 

Correct on this. HLSD has no torque transfer from one shaft to the other unless there is torque applied to the crown/pinion gears. What does it do if you try doing it with the car in gear?

 

With the front end still in the air? It would still act like an open diff.

 

You can definitely feel when driving the car that this is NOT a locking diff.. When you hook a righthand turn and lay into the gas, the car does a one-tire burn out.. it's horrible. I really wish they provided me an HLSD trans like they advertised when I purchased the unit.

 

That would be maddening. Are you going to try to get your money back?

 

So I guess the only way to check is lift one tyre just off the ground, put the car in gear with engine running and slowly release the clutch? If car moves forward, HLSD is working?

 

You could, but to me that just screams damage to the car or a person.

Easy limited slip test is going WOT around a corner in a low gear (slow speed, low gear would be best), if you get one tire fire your LSD isn't working (as PlanoSER found out he doesn't have it).

 

Still wouldn't work. If one tire loses complete contact with the ground it becomes an open diff.

 

Eaton Truetrac ones dont, they still spin the lifted wheel but with 5:1(83%:16%) torque bias to the wheel on ground. If the Nissan HLSD is a 3:1, then 75% of torque should be distributed to the wheel on ground due to the helix gears...

A few guys have broken driveshafts with truetrac equipped TT LS1 Monaros(our Ponitac GTO) and still driven home with power going to one wheel

 

I called the sales-rep that sold me the unit and explained they did not provide me what was advertised/not what i wanted.. After going round and round with the guy and him trying to tell me the non-locking units are in his system for a higher price.. I had to lay into him and get some manager names..I asked for compensation for not providing what they sold to me.. It is now being taken to the manager's manager for consideration.. we'll see what they say. The guy said they do have one locking unit trans in their network he could swap me out for but it has over 120k miles on it, ugh.. I went on to ask OK if I swap you out are u going to compensate me for having to buy more trans fluid, my time having to de/reinstall, etc.. then drive 45 miles back to their place??? So, i'm waiting to hear back from the Manager dude.. My brother said (jokingly?) that I should swap the vin plates from the new one i have to my busted one and return it for exchange of an HLSD unit, lol.. riighttt.

 

You can tell when you take it off. You can see through the HSLD model. The open diff model you can't.

 

You've got that backwards, you can see straight through the HLSD unit.

 

Oops, fixed that.

 

Actually, you can see through both of them. Looking through the HLSD you see straight through with nothing in the way, a clean circle. On the non HLSD unit there is a round bar in the way and you see a half circle.

 

Well, you can see the pin the spider gears ride on, and some area around it, yes. Can't really see through it as most people would think of it.

 

Right, you can see more with LSD

 

Hey Plano, I picked up my 6th gen 6spd LSD last saturday. i'm going this weekend to get my axle rebuilt and get the tranny put on valentines weekend. i'll be spending time with my car for v-day lol maybe we can pick up some girl(s) on that day. i'm lonly for now. just me and the max

 

Isn't the right side axle longer on HLSD cars? If that is true wouldn't it be obvious that a replacement wasn't HLSD when installed since the original axle wouldn't fit?

 

If anyone is interested im selling a HLSD that fits 04-08 6 m/t.

I tried installing on my 5 speed alti. Had it in there for 10 miles and pulled it out..

 

So how much damage was done to the tranny making you pull it out?

 

with or without is the same. axle is something different. but yea that pass. side is the longest axle in the world and nobody carries the right size for it. stupid huh

 

I think it was due to the install. The dealer f'ed up they didn't allow for the proper spacing. Rather than rebuild i bought used which was much cheaper. Old tranny just needs to be reassembled with another diff.

 

I'm extremely consused about the axle ordeal with this 6th -> 5.5 gen swap.

The dealer has told me on the phone that a 5.5 gen has different axles for an HLSD or non-lsd transmission.

It has been said on this post as well as others that a non-lsd 5.5 gen will have no axle problems installing a newer 6th gen 6mt.

So.. does that go to say that if my 02 max has factory hlsd, that I'd need to change axles to put in an 04+ 6mt w/ hlsd?

 

I didnt change no axles on my 5.5 when i got the 6th gen tranny. dont listen to nissan

 

Thanks for the response Majestic Ken .. out of curiousity, did you originally have an lsd transmission?

 

hey guys, have a personal story to add to this post: 2002 maxima, installed a brand new 04 hlsd 6 spd/06 350z clutch/pressure plate (from dave b,) fidanza flywheel, racetechperformance master->slave stainless steel line.just to possibly save someone else doing this swap a lot of time: i had what i thought was a terrible throw-out bearing noise. turned out i had to adjust the clutch pedal (which i did by tightening the clutch start switch) to stop the pedal from going too far down. it was actually bottoming out the pressure plate diaphragm springs and making a horrible noise. turned out to be a 5 minute fix, except for the fact that i pulled the transmission again to change the throwout bearing. so now it was a day and 5 min fix lol. i cant seem to upload pics either but since i pulled the tranny out after that initial startup i took some pics of where that grinding took place--it's right near the starter housing.i can also verify a good way to tell lsd/non lsd is by looking through the axle holes. it's been said here before just re-iterating for guys going to junkyards who have no clue about it: the lsd's you can see right through the axle holes, non-lsd's have a shaft going through. "you see more w/ lsd" as someone stated!

 

Why not find an HLSD A34 tranny with an LSD already in place?

 

Oops, sorry, I didn't read that part. Anyhow, you seem like a legit member and your only 2 posts are more informative than 95% of the posts from most 2 post members. That and you're seeking new (to me) and relevant information, so I gave you a new thread in the AM section because I sure as poop don't know the answer. :

Excellent thanks for that

 

I have a 2000 Maxima SE 5 spd (open diff)--what year/model axles would I need for the 6th gen 6 spd swap?

If I find a 20th anniversary 5spd with the lsd, will it be a direct fit, or would I need different axles as well?

Thanks for the clarification,

Vince

 

You would need 6MT axles for the 6MT swap, or a VLSD driver's side axle for the AE trans.

Also note that the 6MT swap is more involved than just bolting the trans on and changing out the axles.

 

Thanks for the info. My trans took a dump--hit a pothole with the left front wheel (blew tire, ding'd rim). Axle seal is leaking (due to play in the left drive shaft), and there is a bit of a whine. Got a bad feeling--it's either overhaul or find a used one. AE VSLD would be nice.

 

hi i have a 1989 maxima 5speed mt and would like to know if anybody knows if i can get a 6spd trans in my car in anyway?

 

First of all you will probably need to get a VQ as sincerely doubt a 6 speed will bolt on to a VE or VG. Of coarse you k now that opens up a completely different can of worms.

 

has anyone actually attempted to do a 6th gen auto swap into a 5.5 ? id be extremely interested to know how it went as i am on my second trans. about to have it rebuilt with a transgo full rebuild kit!

 

Nope.
