Well guys, this is what I have for a picture right now, does anyone recognize the numbers or anything else from this tranny. I included the truck plate, which obviously who knows if the tranny is original, but either way, I gotta figure out what I have (next week comes my 300, inline 6)...








help PLEASE!

 

Probably a NewProcess 435.

Have a gander here.

Domestic Truck Tranny Guide

 

Do the NP 435's come in a variety of sizes? I'm almost positive my tranny is ALL cast iron...







I'm also wondering, is there a very slight overdrive gear for these tranny's? Something I could pop in there for like a 1-.90 or even 1-.80?

I'm bolting this tranny up to a 300ci inline 6 (I hope), as soon as I positively identify the tranny I'll go looking for the bell housing adapter.

Thanks for the help y'all!

 

Oh yeah, and where in the sam hill do I put the tranny oil in? Is that something you have to crack the case for? I found 2 plugs, and zero places to fill er up. This thing looks like she'd take a couple gallons of oil...

Thanks again!

 

That data plate shot says "5 dir" which would make me guess this is a 5 speed direct transmission.

It looks larger than the NP435.

Is there a shifter on it, is it a 5er?

I looked for and found some pics of the NP 542, but it looks slightly different than this trans.

As for finding an OD gear, no chance. They may OD transmissions, but if this one is direct, you'd be better off to keep looking for an OD.

 

Yes, this is a 5 speed tranny if you count granny gear (which since I'm hauling super heavy loads, I definitely do!). There's a shifter, but has been shifted clean of any key or code evidence that was once there...

I'm not too worried about the OD, I may just have to change the cam in the rig, but 55 is plenty for me, I have no desire to set ANY speed records with this baby.

Is there a definitive list of NP transmissions anywhere? Did they make a book? How come there's no NP website?

Thanks for your help guys and (or) gals, this one's eating me up... Just don't know where to look or who else to ask...

 

Could be a 540-541 series would be my guess.

 

You are right about 540 or 541.
I missed the 5 speed on the tag.

 

Drum roll please................................

It's a new process 210 tranny.

Now the Million Dollar question... Is it worth anything? What gearing does it have? Will it be suitable for extreme towing?

 

For a minute I thought it was another Charlie Sheen post..........LOL

 

I'd be interested in where you got the info.

 

Ole Tom at Transmission exchange in Portland, OR. Said he had the tranny cast numbers, and that the tranny is totally obsolete, 100%, and he has no parts... Now, with that being said, I now would like to know if it will bolt up to my inline 6, and more than I want to know, I want it to DO - bolt up to my inline 6!


There was also a mention that the transmission was "light duty," which seems kind of odd to me, since it was in a huge F-600... seems like a lot of tail chasing, and little production... but I doubt it will get put in by itself...

 

NP 210??? The 218 and 219 are transfer cases. The 5er transmissions have numbers like 540, 541, or 542. Makes no sense.

As for putting it behind your six, you need to check pilot diameter to see if it will fit in your crankshaft. You need to check pilot length vs. your bell. And most importantly, you need to check the bell to trans pattern to see if it matches, or can be made to work via drilling and tapping the bell.

F600s also used NP435 and BWT98s, so the transmissions could be called "light duty" compared to HD truck transmissions--it's all relative.

 

You are right about the Xfer case numbers.

The 540 series makes the most sense.

 

I did ask in every possible way, if what he was talking about was a transfer case. He said "no, do you see any aluminum on the transmission? Do you know why you don't see any aluminum? Itsbecause that 210 transmiyou have is a 210, not a 4, or 500 series like are popular..." there's one for sale at heavy duty trucks.com or something along those lines... says 210.

Believe me, it would make me very happy to have a well known problem. Nobody has ever heard of that 210, and the guys that have heard of em, don't know much about em...

With that being said... thanks for the posts on what to look for to bolt it all up!
