Is the 5th gen manual tranny really stronger than the 4th gen?

Are they both operated via linkages (4th gen), or is the 5th gen cable operated (as in the 2002+ Altima 5 speed).

I am aware that the transmissions and VQ Block can be "mechanically" mated, I would like to confirm that the 5th gen manual tranny will allow me to keep the existing linkages.

 

So nobody has thrown a 5th gen tranny on a fourth gen ?

 

4th gen trannies and 5th gen (00-01) are the same, a direct replacement nothing extra need to be replaced.

 

Are you aware if the 5th gen tranny is any "stronger" than the 4th gen?

 

Its a Myth at the moment, some members have pulled apart the trannies and measured the gears to come to the conclusion that nothing has changed..

 

I believe it was Neal who confirmed it. Same size, and unless it was made of better material then it seems to be the same. NmexMAX (I think) was saying the synchros are stronger in the 5g tranny

 

But I'm not sure on that either, as I'm sure people will start blowing them sooner or later ... Props to Neal to confirm the physical gear dimension mystery though.

 

Do you mean the clutch, or the actual transmission?

 

tranny, its in the quote in your post.

 

i thought that third gear in 5th gen 5spd was made stronger

 

And there is the rumor

 

I know that, but the sometimes people consider the clutch part of the tranny, (technically it is) and I have heard that that is better, or am I disseminating another rumor?

 

I've also heard and heard people testify that the 5th gen clutch grabs better than stock 4th gen. I will test this out when I do my clutch job and will find out 1st hand.

 

No. Yes. It will work just fine. It will move your shifter back about 1 inch.

 

Don't forget the input shaft bearing issue on 4th gens that was fixed on the later transmissions.

 

How do you know this? I'm tranny shopping and want to get the 5th gen tranny as it shouldnt have the bearing issue but I dont know for sure.

improper shimming was still a problem right?

 

I can verify this, I just did this 1 month ago, It is def a lot stronger and holds alot better then the 4th gen stock one.

 

Thanks for confirming the direct fit; other than the shifter moving back an inch. This is probably good considering that my B&M short throw is pretty far up.

 

I've always heard, online and not, that transmissions built after a certain date were not as vulnerable to the bearing problems. This would mean not only 5th gen trannies, but also 4th gen replacement trannies built after 2000 or something.

Theoretically, I suppose all those people could be wrong, but seeing how common the input shaft bearing problem was on the 4th gen, it seems reasonable that they'd fix it on the 5th gen, especially since the 5th gen was a little heavier and more powerful.

 

Well I just put in the 5th gen clutch and honestly I don't feel a difference. There is no harm in doing it. But I haven't felt this life altering difference as others have.

 

No one said it was "life altering." Thats a bit over the top.

 

Well I was overly exaggerating but I don't feel a difference whatsoever. I'll have to drive my friends Maxima and see if there is grabbing difference in clutches.

 

Except that the bearing problem has nothing to do with power nor weight, and the fact that most 4th gens weren't to the mileage at which the bearings start to fail yet when the 5th gens were being designed, built and sold. It's concievable Nissan didn't know the problem existed until lots of 4th gens started hitting 100k or so miles, or that they just did it to save money (using the same shims in all trans) so they just didn't care.

Once we have lots of 5th gens starting to hit 100k miles we'll probably know which case is true.

 

im in no position to argue wit neal, cause he might slap me with the , and he has also seen the inside of the 5th gen tranny. but i have had both in my car and im gonna say the 5th gen tranny feels better shifting then my old 4th gen one. but thats just my opinon.

 

that statement would be true because your getting rid of your 4th gen tranny for what ever reason, and the 5th gen is in proper working order, so you may be comparing how the 4th gen felt, to how the 5th feels.

 

I was just thinking it might be important to work out the tranny issues since the greater power and weight would put more stress on it.

Good call on the mileage thing though. The only counterpoint would be that Nissan would have test cars that would probably have been driven past 100k miles before the 4th gen was even halfway done with. Either way, you're right... we'll really just have to wait and see.

 

The same could be said for the 4th gen too while it was being developed.
