duramax 6 speed

[blazin_blazer]

i see in some peoples sig line they list a duramax-6 speed...is this the automatic allison tranny or is it a 6 speed standard trans? if its a standard can it be used behind a bbc and in front of a 32 spline np205?

also how hard is it be to get a nv4500 to hook up to a 32 spline np205?

I think that the 205 might bolt straight up... And yes, there is a 6 speed standard behind the early Duramax engines. I can't imagine why it couldn't be bolted up behind a BBC, so long as the crank offset isn't different...

It could be either. A six speed manual (ZF S6-650) was available until early '05 (I think). I don't know of any adapters for this transmission, I believe it has a standard Chevy bolt pattern but you're on your own for t-case adapters.
In mid '06 The ONLY trans you can get with a LBZ Duramax is a 6 speed Allison.

NV4500s are quite easy to adapt, contact Advance Adapters for t-case adapters, and run a search on this site for all the ins and outs, bellhousings, clutch linkage etc.

Let me see what I can do for you. I have 2 D-Max/ZF6's . They quit making them on Dec 11th 06'. That was the last day you could order one .
A 32pline 205 will not bolt up because the ZF6 is a 29spline like the Dodge nv4500. An Atlas will bolt up to it though I'm told. I'm in the process of trying to gather the info to get a 205 behind my 01 because I sledpull it and don't much care for the np263.
The ZF6 for behind a 8.1 is the same IIRC but requires a different flywheel.
A nv4500 will bolt up to a D-Max with a custom flywheel and than you can use a gm nv4500 with a D60 swapped in .

One guy I know has a D-Max/nv4500/205 with a D60 up front. Not finished but it will be sweet.

Any more questions feel free to ask .

Is there a passenger drop 29 spline Dodge 205 out there?

 

[1967k10]

No,but there is a Ford 31spline and a Dodge input could be used. Not sure the Dodge 205 has a male or female input. Anyone have one handy??

Yes there is. Gen 1 dodge cummins with the getrag 5 speed had a passenger side drop, 29 spline imput.

I also converted a Dodge NP241 passenger side drop to 29 spline with a input shaft out of a LH drop 241

10-4 on that.......I have a passenger drop 29 spline 205 in my garage. uses a 29 spline coupler just like the 465/205........this will bolt directly to the back of a NV4500.

rare though, only application was as said 1st gen dodge behind the 5 spd getrag.

So GM ZF6 Dodge coupler,adapter and input and a Ford 205 with a 91 GM VSS should work in my Duramax??

 

[DEMON44]

Hahaha.......great minds think alike! Waaaaaay ahead of you brother........
Although I have no idea what the back of a Gm ZF6 look like....this is on the back of a NV5600 which is identical to the NV4500

this is my ford 205 thats going to get the Dodge input and an advance adapter............to replace the 241 in my Dodge when the 'ol cummins grenades it

 

[1967k10]

Cool!!!

Like blaker said, cummins dodges with the getrag is where to look. They have a male input gear, with a sleeve like the 10 spline 465 setup.

 

[1967k10]

What about 1ton dodge gassers? They have 29splines too.

 

[blakerj1]

I believe only the V10's did and that is a driver side drop T-case.

 

[1967k10]

I'm talking pre 93 1tons. I parted a 90 a while back and it had a 29spline 205. I just found out this will not work if you want the VSS to work cause these use a different current to make it work .

GM used the DRAC to convert the 40 pulse, does dodge use different?
