6spd 4th gen?
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 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!

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.

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.

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.

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.

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.
