Have access to an extremely cheap 6spd tranny from an 03 max,with 23k miles on it.Is there a way to fit it into the 4th gen (95) maxima? probably a good amount of work,but let me know because this will be my winter project.

 

I am sure you CAN fit it.... but to what extent you need modification I don't know?

 

I think that the 5th gen trans is cable operated instead of rod operated like the 4th gen, or vice versa, not sure... When people do a VQ35 swap i hear they do a 6 spd swap also...not sure, hit the all motor forum!

 

ask tilley he has one done

 

no when the va35 swap they keep the 5mt. the 6mt is more work to get working thant ther 5mt which just bolts up no moddification.

 

it's been done

 

You're better off with the 5th gen tranny. They mainly bolt-on w/o much modifications. Read this.

 

If you already have a 5-speed, forget the idea. If you have an auto and you're going to be bored all winter, go for it.

 

See if you can get the engine too. My understanding is that it is not a bolt up.

 

In addition the 5speed tranny benefits the 3.5 more than the 6speed would, so if you ever plan on doing the 3.5 swap I'd suggest keeping the 5speed tranny in there

 

oh I know. I would keep the 5MT for many many reason, price and better gearing being tied for the number 1 spot.

 

I have no doubts you knew that MDeezy. Just thought I'd add to what you said for the less informed members to see

 

Gotcha.

 

What the hell are you talking about???

I just realized the thread is for a 6MT to be put on a Vq30de. I thought you meant the vq35. . . I dont know what I was thinking.

You can match it up but custom work will be needed and your gearing wont be any better, you'll acutually lose power (drivetrain loss for a 6MT is greater than a 5MT) so you may loose about 10-20hp.

 

Dude, you're talking to yourself .. ...

 

I did a 6spd swap on my boosted 99. lots of fabs required

 

yea. . . didnt feel like editing the post was very

 

I forget, whats the purpose in having more gears again? The ratios still seem to be smaller on the 6spds than the 5, so what gives?

 

Better gas mileage

 

Apprarantly that's the only advantage. Lots of fab work with barely any net acceleration gain plus more drivetrain loss. I'd keep the 5-speed, keep my tire pressure up, and cruise at 65 on the expressway.

 

Best part of a 6spd is 6th gear 100mph@3200rpm.....

 

"better gearing" in 5-spd? you've got to be kidding...

 

Shorter gearing doesn't automatically mean "better gearing" since it requires more shifting. The only way to know for sure is Cartest where the ONLY variables are the gear ratios.

 

that would be sick

 

Listen to the nismologist

 

100mph@3500 is still sick

 

dude you are not going to lose 10-20 hp if you swap to a 6 speed.

 

Dude, youre getting a Dell!

 

1. Gear ratios and final drive are almost identical between the 5-speed and the first five gears of the 6-speed. The only significant gearing difference is an additional gear on the 6-speed for highway crusing.

2. The additional gear DOES rob some power and make the transmission weigh more. Not by much, though.

3. 6-speeds are available with helical limited-slip differentials (HLSDs). The HLSD operates in the same way as a Quaife. If the 6-speed you have access to has an HLSD, and you feel like doing a lot of work to fit it, it would be well worth it (MUCH better traction, no more torque steer).

4. All 5-speeds are linkage-operated. All 6-speeds are cable-operated. Plus, the 6-speed mounts differently. This means that installing a 6-speed will involve a lot of custom work.

Personally, I'd much rather have a 5-speed with a Quaife, or even just a VLSD 5-speed: lighter, more efficient, and bolts right up. But I won't even try to tell you that having one more gear wouldn't make highway cruising a lot nicer sometimes.

 

actually the mount for the 6 speed does not require custom work. the 5 speed mount is spot welded to the frame and the 6 speed mount is bolted.

the question i have is where can i find the diff from a hlsd model 6 speed and put it in my 6 speed.

 

Bingo!!! Last time this topic came up I went and found all the gear ratios for the 5spd and the 6spd and they are like you said almost identical. As I stated in the other thread about this my major concern with the 6th gear on a 3.0 would be would the gear be useful at speeds of around 65-70? I beleive it would put the revs at around 2500RPM for those speeds and any kind of incline or need for acceleration would require a downshift to 5th, and i know for me that would drive me nuts...It does on my VR-4, 5th gear on that car is so long that at 70 it is barely running at 2500RPM and hills or a desire to pass usually requires a downshift to 4th or 3rd if i really wanna get on it

 

Heh, thats a nice car you got there. Technology not too much of a handful during repair time?

 

My car is actually quite reliable...but thats a topic for another thread or IM

 

i dont mind down shifting from 6th to 5th or even 4th on my 6 speed. for me gas mileage is important especially cause of the gas prices right now.

 

dam bro, your 18 and working as a nissan tech?

 

I'm 18 and Nissan asked me to work for them.....
Just because you're younger doesn't mean you don't know your stuff...

 

Oh yeah? You had to go to an automotive school first, right?

 

yeah I am...

 

i didnt go to any automotive school after high school. i took a automotive class for 2 years and got a certificate and showed it to nissan and got hired. currently right now i am getting my ase certificates and will be going to school soon when nissan sends me to their facility

 

Come on guys!!! You're not really serious about getting the 6th speed tranny because of better fuel efficiency. I mean be honest here, if y'all are then why even do any bolt-on performance upgrades or even do a VQ35 swap. The real reason is because y'all wanna go faster!!! IMHO, getting the 6 speed would be pretty useless as you'd rarely use 6th gear especially if you do alot of city or freeway driving where your freeways are mostly congested anyway. You'd rarely even find it necessary to go to 6th gear when you can't go fast enough up at a certain RPM where you'd need to upshift to 6th. I'd see the feasibility of this if you live in Germany and you drive the Autobahn daily.
