I would keep the stock intercooler and stock intake manifold and use the money you will save for a dual disk clutch and an upgraded input shaft.

so who does the these transmissions? bc i have had at least 4 that i can count for sure and maybe five. Everyone of them had the updated nut and 5th gear still fell off. Once that happens the best thing to do is just weld it oon. You can tack it but that dont help so i just weld the u-no-wut out of it and then when the tranny is actually broken you gotta start over. where can i get one that is ready for this hog i am building? I was reading a different topic on here that waas posted about converting to a six speed and the overall tolerance for the six speed was higher. I dont know exactly how much or anything but it was rated for more torque. and like i said im kinda fed up with it. They say that you can keep from the fifth problem by not ragging it in that gear at all. So when i bought the last transmission, i stopped pulling trailer and made sure i had 4th wound up all the way before i shifted into fifth. AND STILL fifth gear ell off. So i welded it and it was fine, but umm, it whines alot on this one so im ready to try something new. Anyone help with this?

 

We have yet to have a 5 speed with the upgraded components fail on us. We have done many of them, and the majority of them for guys that tow way over weight.

 

well thats what im doin and like i said, the upgraded components failed. Are you the guy building them or what because if thats the case i might be interested in buying one. I will put yours to the test as well. Everybody can be as sure as they want about it but i am tellin ya that fifth gear has fallen off everytime. I just feel like there is a lot to be left desired.

 

how the hell do you put pictures on here

 

Easiest way is with a Photobucket account and then copy the IMG code and paste it into your post. Other than that you have to do an attachment. After writing your post, scroll down below the smilies and you will see a button for "Manage Attachments".

As for our 5 and 6 speeds, we have a local guy that builds them for us. Out of 20 something 5 and 6 speeds in the last 5 years we have only had 1 failure, it was an input seal on a 5600.

What are you doing with the truck that would overload the 5th gear so much, assuming it was properly assembled?

 

sskip the stage one injectors and get some sdx 5x12's

 

I am just driving it. It gets the occasional load of hay up a pretty good grade on an interstate which right now the truck dont have the ***** but it will hopefully after the buildup. Like i said i have heard driving habits do it to it and everything, but i have never had one that was built up or anything. Where would i get one that is built up or in good condition? Who would i contact? I think i will start a second thread to get this out there for others to see. Thanks alot, will check back here also.

 

something has to be wrong, there is no reason you should be going through that many nv4500's just driving and sometimes towing.

 

Unless all your doing is flatfooting it every where is fifth you shouldn't be having these troubles
