Altima gears in a 4th gen
Hey, I know you can use altima gears in a maxima 5spd (I'm going to use 1st, second, and fifth) for better acceleration and better gas mileage, but are they a direct swap in? What else is needed? Do I need second gen or first gen altima gears? I have a spare 5spd tranny i'm throwing this into.
I know at least one person on the .org has this done (he has splitfire coilpacks and jwt cams as well) I just forget his name.
Thanks for any input.

I know JClaw has the 2001 gears in his tranny, but he broke 1st gear, and i'm wondering if I buy the tranny from a 93-97 altima (has the same tranny code as 4th gen max), and swap the bellhousings, will it fit and work just like a 4th gen tranny would?

I had 2001 Altima gears in my trans, but I put the stock ones back in. Here's what it did to my times (on street tires):
Best (street tires, stock gears):
60': 2.13
1/8: 8.88
1/4: 13.68
MPH: 104.54
Best (street tires, altima 1st and 2nd):
60': 2.06
1/8: 8.97
1/4: 13.79
MPH: 105.29
Somewhere between the 60' and the 1/8 I lost momentum because there is a bigger drop off between 2nd and 3rd and it's hurting you. The car will "feel" a little faster in the first two gears but will slow you down overall. It helped the 60 foot but overall it was a pointless experience.
If you want to do something worthwhile, change your final drive. You can't really do it with a VLSD (16 bolts on the diff).
But if you have an Open differential you will have more options. Look around for the 4.471 axxess ring & pinion. There's also 4.167 available. Look around used transmission shops.
As for gas mileage/highway cruising. 4th gens have a 0.795 5th gear stock. All 1993-2001 Altimas (and 5-speed Stanzas) have a 0.740 5th gear. That would lower the 5th gear cruising RPM at 75 MPH from ~3000 down to ~2800. The gear is a direct swap.
My local used trans shop had the gear for 40 bucks and it costs 50$ to have it mounted on your shafts. But you have to install them in your trans yourself. I did it myself with no prior experience so it's doable.

besides Jclaw, that's me with the altima gears.
I hate to negate Jclaw's comments, but I don't have the torquey 3.5L engine in my car, and my car has been modded to do insane high end works.
My theory is:
Since I have been modding to gain up on the high ends, I am losing torque down low. Adding this 1st and 2nd gear helps me at getting a better launch. However, I am still depending on my high end mods to kick in after 5k rpms. With a mevi, cams, and jwt ecu, shift point after 1st gear is at 5450 rpms, high enough to stay on my power band that mevi provides after 5k. 2nd to 3rd gear shift point drops down to 5100-5200 rpms, which is at a good zone where mevi just kicks in and provide power again. JWT cams picks up from 3500 rpms and it gave me strong arms consistently till redline, I don't feel a "dip" in power at all. The reason I aimed for the shorter 1st and 2nd gears from altima is to compensate that huge torque loss I have with my mods. Overall, I think altima gearing helps with my launches.
The bad news is, prolly because my engine is old, i did three cams installations and then after a few weeks running the cams, water got through the intake and with that incompressible fluid in the chamber, they snapped my cams. So now I'm back to stock cams.
I got my hybrid tranny from h2kfrosty; I remember he told me that alty gears are out of 2001 trannies. I strongly doubt that pre2k alty trannies will work with our bell-housing.

All KA24DE altima tranny internals will work as they all have the RS5F50A/V, however only the 2000-2001 have different ratios. The 94-99 have the same ratios as the Maxima, so unless you just wanted cheaper used internals and didn't mind swapping the bellhousing it is useless. Some of the F/Ds are different I think.

Why not use the 3rd from another nissan???
There was one member that used a 3rd gear from a completly different nissan, don't remember from what car. If the gear from the altima is the same I'm sure nissan made more trannies that have gears that swap right in the maxima transmission.

I was worried about me just burning up first and second with the 3.5 and altima gears, and the power drop off in third. I guess i'll just rebuild my spare 5spd with the stock gears attached.

Anyone? I already purchased my bearing rebuild kit yesterday and I would have liked to ordered the correct part number from nissan yesterday too to minimize downtime but Ive went through pretty much all the altima 5th gear threads and couldnt find this info anywhere. Everywhere it is just mentioned as vaguely as that: "get the altima 5th gear". However, I have a slight inclination that it could very well be both those part numbers Nismology had mentioned since they mate together?

Every time I've changed gears in a tranmission, the gear on the input and the gear on the main shafts both need changed. Because the shafts are a fixed distance apart, if you change the ratio (change the diameter of the gear) you must change both gears as they are a set.
