Sup I'm just wondering if anyone else has straight cut gears in there max? I assume my 1st n 2nd are straight cut since they have that whine noise to them?

 

Straight cut gears are an option when building one, link somewhere here.. But your first and second should be quiet just like the rest..Your noise may indicate a problem.

 

I'd check the gear oil level.

 

Hmm. They been like that since I 1st got the car in August 2k10 so wouldn't low gear oil mess it up by now?

 

none of the gears in the maxima are straight cut (except reverse).

i have straight cut 3rd and 4th in one of my maximas.

 

So are straight cut better? I seen a few built sti that have straight cut on all gears

 

They are stronger, but I've never seen a maxima with broken gears. Probably not worth the trouble or price.

 

There are plenty of maxima with broke gears. There used to be a lot how high power heavy racers in the maxima platform. The trans has always been one of the biggest set backs. There are only two Maxima trans with PPG straight cut gear set that I know of Nealoc187 owns one and the other was in 96sleeper car not sure where that trans is, but I'd love to have it. Daily bolt on maxima will not need them, however great to pair with the almighty Quaife for serious high power racers. Neal has thrown plenty of power at his trans and he still does.

 

I'm going to bet you have bad input shaft bearings if your tranny is whining in 1st and 2nd.

no, you don't need straight cut gears. they whine horribly and are stupid annoying for a daily driver. for a race car, just fine. but if you're asking questions like these, you don't own a race car...

 

ok not in 2nd but how about first? isn't anyone elses first gear louder than the rest? not the same sound as a straight cut gear like reverse but just louder?

like in this vid 32-35 secs

 

I have noticed the first and the second gears that are sounding like what your saying, It sounds like an American car that's Supercharged. Whining whistling sound.
