Title: 1/2 ton 5 speed
Post by: Brian on September 23, 2009, 08:07:19 PM
Now my question...Is this tranny stout enough to use in my Heavy 3/4 ton truck? I do haul some good loads and pull the occasional loaded car trailer. Don't want to waste my time if the 5 speed is gonna crap out or break under a good load.

I believe they used a different trans in the 2500 and 3500's
 
Be careful. . . The gear ratios are differnt.  The final drive is lower with the manual

Yes, because the final drive is an over-drive.
 
There are/were two five speeds for Dodge Trucks.  One is a lighter duty for V-6 and 5.2 V-8s, the other was the heavy duty.  Steve is right about where you would regulary find the HD vs. LD.  However, I've seen the HD 5-Speed in a 1500.  I'm sorry I don't know the numebrs designation for each trans, but they are built by NewVenture.
 
If I was at home and wearing differnt clothes I would crawl under my Dakota and tell you the number on the LD trans.  Sorry!

The automatic is OD too.  But the ratio is higher on the auto than it is with the manual.

The tranny was behind a 5.2.  So if it's a LD you don't think it would be a good idea to drop it behind a 5.9?
 
I'll do a little research and see what I can find on the HD vs LD 5 speeds.

Here's what I found Brian. 
 
There are 3 types: NV1500, NV3500, and NV4500, and they are defined as Light, Medium, and Heavy Duty.  According to my Dakota book the first two can be found on Dakotas, but only up to 318s on the 1500.  The 3500 was used on 360s.  According to a web site on New Venture Transmissions, the same was said, but the 4500 was only for V10s and Diesel usage.  It did say the 3500 could be found on 318s and in some 1500 trucks, but ususally was in the larger 2500 and up trucks.
 
Based oin this, if the trans you've found is a NV1500 I would not use it on your 360.  Sorry Buddy.

Thanks for the research there Snotty...(http://www.moparfins.com/forum/smileys/smiley4.gif)
 
I scrounged around the net and came up with similar...but different info.
 
I found the NV3500, as you stated, on the V6 and 5.2.  And then only in light duty capacity.  I found a stat that listed the NV3500 as having a 300ft/lbs torque limit.
 
I also found that the NV4500 had a couple different versions.  There was the regular duty and the HD version (V10 and diesels)  The regular NV4500 can be found on the dodge ram 2500, and some HD 1500.  But was a extra cost option.  It was used behind the 5.2 and 5.9 V*'s as well.
 
I found a site that listed all the tag info for the NV4500's, dodge and chevy, so I'll take that with me.  It pretty obvious is it's the NV3500 vs a NV4500 since the bellhousing and body on the NV3500 is all one piece.  The NV4500 is a standard style with a detatchable bellhousing and body.

Thanks for the help and info guys....I passed on the NV3500.  I had found a link from the other night and just didn't like the 300ft/lb torque limit on the tranny. 
Plus some of the other info I found stated that these trannies are only good for about 100K and then need a rebuild.  And the NV3500 being a 2 piece tranny, and needing special tools for a rebuild, and usually costing over $1000 for a rebuild I thought I'd pass.
If it had been the NV4500 I would have definetly jumped on it, but I guess that is the reason he hasn't been able to sell it.

Glad to be of help.  For my Dakota I wish I had the 3500 - and a 318 to go with it!  I have the V-6 and the 1500.  It serves me, but I wish I had the better power.
