yea man you def. should get a 6th gne HLSD. What I like:

- 3rd gear is much MUCH better...it just slips right in even at higher rpms
- the car revs up much much faster

What Im not crazy about with this setup:

- clutch engagement point is much much higher than previously which has caused me to stall out once. Its just a matter of getting used to.
- When I start the car it sounds different...like a clattering noise. Is this normal?

 

Hmm i going to pull my tranny soon aswell..
Im on an automatic, would the 6th gen AT's be the same fitment and specs as a 5th gen 2000 maxi's tranny?

would i have to have a 6th gen ecu and stuff?

would i notice any performance increases?

 

Your question has nothing to do with this thread's topic. Please start your own.

 

You can adjust the engagement point to be lower. There's a threaded rod that runs from the pedal into the master cylinder. It's been a while since I did it but there is a how to somewhere here if you search.

The Fidanza flywheel is a little louder on startup. Some of the older ones had a problem that caused a loud grinding on startup but that was obvious. It would turn heads in a parking lot. If it's just a little louder that's ok.

You can check the bolts holding the starter. If those weren't torqued down it will make interresting noises.

 

GEEEEE OP thanks for the great help!

its a thread about putting a 6th gen tranny into a 5th gen car... and i wsa talking about putting a 6th gen tranny into a 5th gen car.........i can see how that got alittle confusing for you.

but thanks for the great help. i just figured id save some forum clutter if a brilliant mind could answer this question for me.. without/instead of giving me the George Bush run-around.

 

sarcasm will not get you anywhere but thanks anyway. If you will see, I did not get a chance to reply to your post, someone else did. Make another thread and get your answer

 

done.

 

hmm...on my old tranny at 60mph in 6th gear the rpms read the same as my tranny now ....whats up with that?

 

@ 40mph...

for a 5.5 6mt:

2nd Gear - 4-4100RPM
3rd Gear - 27-2800RPM
4th Gear - 21-2200RPM

for me right now:

2nd gear - 4500rpm
3rd gear - 3000rpm
4th gear - 2300rpm

6th gear for both trannies seems to pull the same rpms at 60mph although every other gear seems to be different

 

probably tach error, there is a 10 mile an hour difference in 4th gear between the two trannies at redline.

 

ok thats great to know..thanks

 

Pics look good, congrats on the successful install...

This looks like the setup I want to get(except maybe the clutch) when my transmission goes...

 

thanks man...

if you have the 5.5 tranny or the 6th gen 6mt, what are your rpms in 6th gear at 80mph?

 

i replaced the 03 tranny with the 06. Not sure what the rpm's are at 80mph. If I remember I will look next time

 

thanks knight, that would be a great help

 

also, my mpg before the swap was 22 and now...18 lol. Im guessing its because the gearing makes the rpms higher in each gear. But damn...thats a big dip. I have been pushing the car a lot but I also pushed it a lot before the swap and had a consistant 22mph. I'll go easier on the driving now I guess

 

I didn't really see a change in mileage. It could be that you're just pushing it more "testing" it out. My mileage always drops for a while after a mod. I think in the long run you'll see the same mileage you always have.

I've been getting about 24-25 with some easy driving and some hard driving thrown in. I drive about 25% highway. The lower gearing will really only make a difference in the highway because you can just use a higher gear in town.

Also, check to make sure they didn't unplug any sensors or anything. You'd probably get a CEL but you never know.

 

my mileage hasn't jumped. It did the second week after I broke the clutch in because I was "having fun with it" but back to normal driving and mileage is the same as before.

BTY 80MPH/130KPh is about 3800 rpm if my tach was accurate.

 

in 6th gear? Thats pretty high no? Or did you mean 2800rpms @ 80mph?

 

crap, I'll have to double check that

 

yea...i dont think it would be 6th gear, maybe 5th...I know someone with a 6th gen 6mt and his reads 2800rpms in 6th gear @ 80mph

 

I have to bring this thread up again...

My gas mileage has suffered after this swap. NOW with normal driving, actually even softer than before, Im only managing 19.0mpg compared to the 22mpg prior to the swap. Im shifting at 2k every shift, even skipping gears. To those who did this swap, what are you guys shifting at for normal driving?

 

my mileage is the same 8.5 litres for 100km, not sure what that works out to in mpg.

bty 28-2900 rpm in 6th gear at 80mph

 

Roughly 27 MPG.

I take it your driving is mostly highway right?

 

50/50 highway, I shift around 4k on average. I run shell 91. castrol 0w30 synthetic. And I have a good tune with the greddy blue.

 

Hey guys, I've been reading threads in here like these, as the tranny on my 2002 Maxima just crapped out recently. I have the opportunity to purchase a 6th Gen transmission myself, but my mechanic brought up an issue:

What about if you're coming from a non-LSD-equipped 6-speed, as I am? I'm not sure where those of you who have already done the swap are coming from, but my mechanic stated that he looked it up, and the axles between a 5.5 6spd w/ LSD is supposedly different from those in a 5.5 6spd w/o LSD. Also, he stated that the axles are exactly the same between a 6th Gen with or without HLSD.

Is this true? If I purchase a 6th Gen tranny, I might also have to purchase axles?

 

youre fine man...I had a non-lsd and got a 6th gen hlsd. works great

 

Awesome. Thanks for the reply man.

Edit: Part's been ordered, and should be at my buddy's shop in 2 business days.

 

BTW: How much quicker was the car afterwards? Was it noticeable? I'm actually getting the 6th Gen tranny more for practical reasons, as it is actually much cheaper than just getting a replacement transmission, but I am glad for the "perks" (HLSD, more aggressive gearing) as well.

 

i got it with fidanza flywheel and stage 3 clutch so I cant tell you what the tranny did by itself, but it revs up MUCH MUCH faster now

 

Your car will be faster with the 6th gen HLSD. When I did the swap I was racing a lot at a local 1/4 mile strip and could never break into the 13s. The weekend after I did the swap I did it several times. The tranny was the only thing I changed. I didn't even touch the clutch since I had just changed it.


Your car will also handle better and drive a lot better in the rain.

About the axles, your axles will fit just fine.

 

That's great to hear man, and thanks for the response.

I got a deal off car-parts.com for a 2004 Maxima locking diff transmission for $877.65 shipped, along with a 90-day warranty. The tranny is graded as an "A," and has 46K miles on it (my car just recently passed 100K - mostly freeway miles). I hope that's as good a deal as I think it is, considering a remanufactured replacement from the dealership would have been $3000, and a rebuild of my stock tranny would have been around $1500.

I just recently got a new clutch and flywheel set myself, so I am set on that front. I'm also getting the motor mounts replaced, as those are going as well.

What other mods do you have, in order to get into the 13's? I'm not a drag racer by any means, but I might just take my car after all the new stuff is broken in, just to see.

 

That sounds like a good deal. Almost exactly what I paid with around the same miles.

You should be able to sell your old tranny to a rebuild shop. I got $150 for mine. It was working but had the 3rd geat crunch. They were happy to get it. I should have asked for more. If you call around to a few shops you'll find someone who really wants it.

Most of my mods are in my sig. It only shows on the first post in a thread. If you scroll up to my first responce you can see it. I haven't run since doing the suspension.

 

where did u get the 6th gen 6speed from. im from hamilton

 

2 year old thread and the OP doesn't own the car anymore.

 

I've been searching this topic for a few days and am still left w a few questions..

I'm going from an 02 non_hlsd (I believe non..) to a 6th gen hlsd
Since it hasn't been brought up before I'm sure the electrical connectors are plug and play? No reprogramming needed for a diff vss signal? Is it true that 5.5 gens have different axles depending upon lsd or non lsd?

Also going to a junkyard and looking at the trans what's the best way to tell if its hlsd or an open diff?

tia..
