Paging *Shane* Shep soon to release HD 4th gear.
 

"Just a teaser pic. I will not be showing the rest at this time but I figured you guys would like some proof that there will be a better alternative out soon."
Its awesome, people are posting their stripped gears and Shep is diagnosing them by a pic its pretty funny and of course internet know it alls are trying to explain why its happening.

Anywho, don't give up on manual trans. in DSMs just yet.

How long will the synchros last?

Re: Paging *Shane* Shep soon to release HD 4th gear.
 

5 days, 3 hours, 26 minutes, and 12 seconds of driving.

Rough estimation, of course. :D

Looking at the page source code, it appears he attempted to hot link the image from the dsmlink web forum. . . . :toiletp:

Re: Paging *Shane* Shep soon to release HD 4th gear.
 

It worked for me, sorry ill fix when I get home

Re: Paging *Shane* Shep soon to release HD 4th gear.
 

its because your linking from the Link forums, which you have to be a member or signed in to see. suggest you right click, save picture as, save it to your computer, then upload it to your post.

That is sexy! Any test proven results? I'm gonna need a built tranny in the future..

Re: Paging *Shane* Shep soon to release HD 4th gear.
 

Title says SOON TO RELEASE, meaning its not out now.

Do u have to worry about 4th?

Re: Paging *Shane* Shep soon to release HD 4th gear.
 

^I don't know but if im gonna do a full build then I might as well get the strongest of the strong!!! :D for my new setup!;)

Re: Paging *Shane* Shep soon to release HD 4th gear.
 

^hmmm yessss (evil voice)

Re: Paging *Shane* Shep soon to release HD 4th gear.
 

Lol

Re: Paging *Shane* Shep soon to release HD 4th gear.
 

LMFAO

Re: Paging *Shane* Shep soon to release HD 4th gear.
 

Is this a custom billet gear, or the factory Evo 3 4th gear you can buy from Jacks? The Evo 3 4th gear has 29 teeth, 1 less then a stock dsm 4th, but its billet and has the double synchro from the factory, the 4 holes in the face of the gear is for the double synchro.

I dont fully understand just replacing the gear, the countershaft is still going to be weak.....

Re: Paging *Shane* Shep soon to release HD 4th gear.
 

Its kinda funny that only on a DSM forum would someone post a picture of a gear, and people would be salivating over its all powerful glory. Like a work of art... not saying that im not salivating but its just funny you dont see this on other car forums.
When i show jessica this sort of thing, and say "Wow hun LOOK AT THAT, isnt it pretty" she doesnt get it.

Re: Paging *Shane* Shep soon to release HD 4th gear.
 

The question is what breaks first, the input shaft 4th, the intermediate shaft 4th, of if they fail at the same time.

Any way you put it its a better part then the factory, it may last a little longer but you put enough torque or hp threw the tranny it will fail, the more power in the less time you have.

The straight cut gear sets available are just about the only option for anyone with a DSM trying to 1/4 mile race with 700+awhp.

I plan to run my tranny until it breaks, then see what I would have to replace vs a dog box.

Re: Paging *Shane* Shep soon to release HD 4th gear.
 

You have a complete evo 3 gear trans now dont you? How tight did you shim it? Let us know how long it last at your power levels!

Re: Paging *Shane* Shep soon to release HD 4th gear.
 

Yes I bought the Evo 3 1st gear and input shaft, the full Evo 3 3rd/4th gear kit from jacks, And I am using a 92 intermediate shaft and center diff.

As for shims I fallowed the factory services procedure. I have it torn down now and from what I can see the gears are holding up great, I used the mitsu diaqueen oil. This tranny shifted like butter at 9500rpm.

Re: Paging *Shane* Shep soon to release HD 4th gear.
 

Straight cut gears should reduce spreading of the shafts, right? So, this will be better because it's straight cut. I don't know anything about stock or evo 3 4th gears though, whether or not they are straight or helical cut.

Re: Paging *Shane* Shep soon to release HD 4th gear.
 

All dsm and evo 3 forward gears are helical cut. Look at the pic again, its a helical cut gear.

Re: Paging *Shane* Shep soon to release HD 4th gear.
 

If it does have a helical cut, it's pretty slight. You can have straight teeth at an angle, can't you? It would just increase strength.

Re: Paging *Shane* Shep soon to release HD 4th gear.
 

When saying straight cut, typically this is what people are referring to (straight cut dog gears like this):

The generate much less (if hardly any at all) side load than a helical gear would generate.

Re: Paging *Shane* Shep soon to release HD 4th gear.
 

I know, but it is possible, isn't it, to have straight teeth, at an angle, but without the helical (curved) pattern?

Re: Paging *Shane* Shep soon to release HD 4th gear.
 

Helical Gear - A type of gear with slanted teeth.

Spur Gear (aka straight cut gear)- A type of gear that has straight, flat-topped teeth set parallel to the shaft
