What Are The Differences Between Automatic And Manual Transmission Truck Transfercases ?

I need To Change Out The DLD In My 96 Automatic Truck.




Sorry For The Capitalized Letters, One Of The Problems Of Owning An Android Phone...
 
Certain DHDs from mid-1996 and up also use a 32 spline output.
These are ID-ed by the 1-piece extension housing, bolted on a main case with a PTO port.

If you need a replacement DLD, I do have a good one from another 1996 with an auto.

I always called those the 2 piece cone DLD with a PTO cover. LOL


I have what would I called a true DHD, it has the larger output, a PTO and an auto input. I would be willing to sell. I don't know the history on it, I purchased it used held it for a spare, and never needed it.

There's actually 3 different "commonly available" DHD t-cases that I have ever seen.

1 version is a glorified DLD, has a multi-piece extension and a small output.
Another is the mid-1996 and 1997 with the 32 spline output and the speedo sensor assembly in the extension.

The 3rd version is the 1998 up, which has a blind hole where the speedo assembly goes.

A 4th version of the DHD is out there, which was used in the last 1/4 of 2002 production.
It used an electric switch in lieu of the vacuum switch in that port, because those last few 2002 trucks didn't have an axle disconnect.
That's a very rare 241DHD t-case that I have only ever seen 1 of.

Then again, how many 2002 trucks WITHOUT the CAD has anyone ever seen?

Will Jones Has One Up In Cairo Georgia And I'm Probably Going To Buy It From Him. I Just Wanted To Ask What All Would Fit Cause Its Hard To Find Correct Info...

yea lol, i assumed he would know that, i was referencing if he with a large output dhd. also think u will need to shorten driveshaft. not sure on that though.
 
As Long As It Bolts On The Trans, Anything After That I Don't Care As Long As My 4X4 Works, I'll Gladly Put A New Yoke On The Drive Shaft And Shorten It...

I've Got A Completely Rebuilt Front Axle Under The Truck With EMS free Spin Kit, Ford Outers, And Inner And Outer 35 Spline Moser Shafts That I Installed In 2009 And It's Never Been Locked In 4x4...

Good info, Looks like I have one of these. But I wish mine was a 29 spline input instead of 23...

I just acquired another one of them, myself.
They are good property, but they still have the early shift pattern, which has baffled a few that put them in the 1998-up trucks, until they figured it out.

I'm lucky I found one when my DLD busted, a DHD with a speedo pickup in the tail shaft, I broke it during a 4000mile trip.
 
A friend reminded me of that over the phone tonight, just gotta source the part. Probably be easier than trying to find a 29 input DHD with the speedo setup I need.

I'm going to make this easier for you.
Go to the link below, which is an Ebay seller I use all the time to buy odds and ends NV4500 and 241 parts.
The link shows 2 different Ebay listings for NP241 29 spline inputs, 1 for a wide bearing, the other for a narrow.

http://www.ebay.com/sch/m.html?_odkw=np241&_ssn=gear5th&_from=R40%7CR40&_osacat=0&_from=R40&_trksid=p2046732.m570.l1313.TR0.TRC0.H0.Xnp241+input&_nkw=np241+input&_sacat=0

There may be other suppliers out there that are cheaper, but this guy is a very reliable shipper.

Wow, thanks for that Mark! I guess I need to tear mine down again to see which I have? I always thought the DLD was narrow and the DHD was wide. Mine's the one piece output with a PTO cover.

I've found DLDs with either wide or narrow, so anymore I always check, or I order one of each. :hehe:

FYI, the one piece extension is "nearly" exclusive to the DHD t-case.
The ONLY other exception to that is the "dummy" t-case (NV023, I believe?) used in the Cab & Chassis trucks that had an automatic and the PTO option.

I stand corrected on the "dummy" t-case, it's model designation is NV021 and here's a pic of it.

I have seen one 2002 60 front without the CAD, would love to swap one into my 99. Right now I just perma locked the CAD in my 60, tired of dealing with ****ty vacuum actuators that never work right.
