Hey guys I'm back again. Just bought a 92 W250 with 239k miles on it. It's totally stock except for the rims. I was wondering how hard and expensive it would be to change it over to a manual. I'd be going with the getrag tranny. Thanks for any input to my situation

 

Finding a good Getrag/205 combo will run you at least $1500, and they are getting hard to find anymore.

 

I believe it has the 205 already on it but I could be wrong. I've seen some for sale on eBay and they all want a core back. Might have to go to my local salvage yard and see if they have any decent ones.

 

What he means by 205 is that it has a different input spline Then the 205 you have now

 

Auto tranny NP205 has a 23 spline input shaft. A manual tranny NP205 has a 39 spline input shaft. The cases, and adapters are different as well.

You can convert a 23 spline 205 over to a 29 spline...but it does require some parts hunting, and machine work. I personally just finished this conversion.

 

Oh ok. I should have known that it isn't that easy to swap them. Haha. How hard is it trying to find the pedal assembly for those?

 

Who makes the coupler with the auto to manual splines? The pedals can be found at salvage yards, I'm not sure what years will interchange but I think several years are interchangeable.

 

You should be able to use pedals from a dodge ram from 1980-93. As for the 23 to 29 coupler i spoke to the guy making them and he said he needs couplers...so your 23 and maybe a 29 so that he can fab it up.

 

Geno's garage has the couplers, not cheap though...Mark

 

So the couple is not a manufactured piece, it's two halves welded piece. Which if welded correctly is probably as strong as a piece splined and not heat treated. Now the 50cent question is who does this mod? Who makes a new splined coupler? Thanks!!

 

When I did this I bought a junker manual rig, sat the two beside each other, and swapped the parts right over. I then sold the rest of the truck. I think the whole affair cost me about $1300 in the end, but that included the clutch.

Of course, a year or so later I dropped $1200 on a rebuilt trans to replace the junker I moved over. ;-)

 

Thanks everybody for the input. I greatly appreciate it. This project is gonna be a little ways down the road as I have this one pickup for the fall winter and spring, otherwise I have my motorcycle to ride to work and back. But thanks again. Any more input is greatly appreciated

 

I just searched through Geno's site....could not find those couplers.

I thought these were the only people making them.

...and yes not cheap. Especially if you have to provide couplers as well. This is why I decided to do the 23 to 29 conversion on my NP205. More work...Yes...but in the end I have a transfer case that I know will not leave me stranded, and can take all the punishment my NV4500 can throw at it.

 

6.7L dodge when your ready to buy a complete set up pedal's and all send me a PM I will Point you in the right direction . I know where everything is at for a swap . guy is going to Auto trans .

 

pedals: You will need pedals from any truck, pre-94', that had a hydraulic-clutch. Don't forget the angle-bracket that bolts to the side of the pedal-bulkhead, and holds the clutch master-cylinder. And, all the hydraulics.

Auto tranny 205 = 23splines
manual tranny 205 = 29splines (not 39, I'm sure it was a typo)
both driveshafts are different.
T-case shifter assembly is different.
Lots of electrical differences. The entire tranny harness is different. Not 100% sure, but I believe the underhood harness is also different. It is easier to swap from an auto rather than to an auto, because of the electronics! (unless you control O/D with a switch. then its easy)

The only good news electrically is that the plug for the clutch safety switch "should" be taped up in the harness under the dash just above the bulk-head connector. It will have a jumper wire plugged into it. Simply unplug the jumper, and plug the master-cylinder in. Otherwise, engine wont crank.

Yes I have been through this several times! LOL
