LOL, trust me we searched the premises already, also it was his boys project so after they lost interest he sold the pieces to me, he never had the original 1982 truck this trans came off of, they were going to install it in their 1984 4x4 and convert it from automatic to manual, very ambitious task, that fizzled

Re: What can be said about the 4-speed New Process NV833 overdrive manual transmissio
 

Looks nice, good luck with it. My '86 stepper came with one originally, and below are a couple of photos. I believe the shifter, boot, and knob to be original. Only thing I changed was the speedo cable seal, otherwise original. Have changed and upgraded the engine a little over time. No power shifting, however, works great once in gear and getting on it (400 HP/400Ft-LBS @ 5600RPM). The overdrive is very nice, with 3.73 gears. I like the 3.73 gears for first too, you can go slow in first if needed.

Re: What can be said about the 4-speed New Process NV833 overdrive manual transmissio
 

Funny how the shift linkage on that transmission is extremely similar to the linkages on the NP203 transfer case. Even the NP203 transfer case got the "Hurst" embossed shift handle :D

Re: What can be said about the 4-speed New Process NV833 overdrive manual transmissio
 

Just wanted to add to a very informative thread.

I've gotten mine cleaned up and found some numbers

I'm assuming that the stamped number are Vin numbers? Can someone advise?

And the pinkish red numbers on the top of the tranny, anyone else have these or know what they are or mean?

Re: What can be said about the 4-speed New Process NV833 overdrive manual transmissio
 

Oh wow, which bolt hole is that lump with the numbers by, hard to tell with that extreme close up, would you mind posting a pic from further away so we all can get a better reference point, it is very interestinng though

Re: What can be said about the 4-speed New Process NV833 overdrive manual transmissio
 

please hold...........

Re: What can be said about the 4-speed New Process NV833 overdrive manual transmissio
 

Its circled in pink. Yes I picked pink and don't know why.........

Re: What can be said about the 4-speed New Process NV833 overdrive manual transmissio
 

Gregski, when you pulled the side cover, did you replace the gasket with a gasket or did you use RTV?

I got her all cleaned up this weekend and Ill be cleaning the snot out of the shifter. Which is complete minus one shifter handle(knob).

Re: What can be said about the 4-speed New Process NV833 overdrive manual transmissio
 

because you're a man's man, lol, and Pink is the new Black, oh wait that so doesn't work, ha ha

Re: What can be said about the 4-speed New Process NV833 overdrive manual transmissio
 

I put it back on with the old crusty gasket just to keep the moisture out of it, there is no fluid in it yet, and I am not done undressing it yet, I will probably take that cover off again for some reason before i am done getting the linkage to work

CAN YOU DO ME A SOLID, a huge favor, can you remove the side cover bolts one by one and tell me which one is that odd bolt out looking one, you will know when you see it, it is one of the 8 shorter ones, but it has a longer neck just below the head of the bolt before the threads start, I don't know which hole it came out of and it don't fit in right now, pretty please

Great pics Dragon, but do you have a pic of the back side of your trans, the one opposite of the side with the side cover, there may be a VIN on that side by the tail shaft bolt holes

Re: What can be said about the 4-speed New Process NV833 overdrive manual transmissio
 

Hahahahahaahahahaahahahah, I read your post about that problem and made myself a "template" that im going to use to avoid the issue that you had. So yes, yes I will. Im going to try to get to it sometime of vacation so within the next week or so. Ill take pics.

Re: What can be said about the 4-speed New Process NV833 overdrive manual transmissio
 

These are the two bolts that I found with smaller washers. If that helps.

Re: What can be said about the 4-speed New Process NV833 overdrive manual transmissio
 

CB1134583 looks like a partial VIN:

C = 2wd
B = 1981 model year (A= 1980, B=81, C=82, etc)
1 = Oshawa Assembly plant code
134583 = sequential portion of VIN - Chevy nameplate

14030811 looks like a GM part number; 3260 might be a supplier unit number or lot information.

I don't recognize the "219" on top of the case, or can't see enough to get some context. Normally that would be the "broadcast code" corresponding to the 8 digit part number (you can see the "DN" or "DH" in Gregski's photos) or the chassis build sequence number (which would be hand written).

Re: What can be said about the 4-speed New Process NV833 overdrive manual transmissio
 

Thanks Keith. At least now I know what year it is. From what I can tell the numbers on top are "12199"

Re: What can be said about the 4-speed New Process NV833 overdrive manual transmissio
 

Thanks, I am aware of these two, I am talking about the third misfit, keep looking, ha ha

Re: What can be said about the 4-speed New Process NV833 overdrive manual transmissio
 

The cover isn't bored larger on that hole?

Re: What can be said about the 4-speed New Process NV833 overdrive manual transmissio
 

its hard to explain its not the width of the neck, they are all the same its the depth of that non threaded neck part, I will take some pics and show you

Re: What can be said about the 4-speed New Process NV833 overdrive manual transmissio
 

Keith is right on with the partial VIN (required by law) and the part number.

The last 4 digits are Julian date of manufacture of the trans.
326 0 is 326th day of year '0', probably 1980
127 1 is 127th day of 1981

All GM trans' of that vintage are marked this way.
Now I'll have to look at mine to see when it was made.

I would expect Keiths' to have a high Julian '6' trans date.

Re: What can be said about the 4-speed New Process NV833 overdrive manual transmissio
 

Good call, D13. Didn't think about a Julian date.

I'm curious now, so I think I'll crawl under lil Red and check that date and also the part number.

Re: What can be said about the 4-speed New Process NV833 overdrive manual transmissio
 

Correct - your shifter, boot and knob are original (appearing) for '86 and '87.

Re: What can be said about the 4-speed New Process NV833 overdrive manual transmissio
 

ok, for those of you who are just skimmnig this, my obsession with this one odd ball bolt will seam extravagant, but as soon as you take your side cover off and try to put it back on you will say, oh o, that Gregski guy was on to something

so here is a pic, the top bolt is the wierd one with the longer neck / or shoulder what ever you call it, the bottom one is like the other six

there is 10 side cover bolts total, 2 long ones, 1 odd ball one, and 7 short ones

Where does this odd ball one go?

Re: What can be said about the 4-speed New Process NV833 overdrive manual transmissio
 

With a shoulder that long the case will have to be counterbored to mate with it.
You should be able to examine the bolt holes to find the one that doesn't have threads flush with the case.

Re: What can be said about the 4-speed New Process NV833 overdrive manual transmissio
 

ok, my turn, here is the number off of mine, I'm glad you brought it up cause I did not even notice there was a number there it was so dirty

CB1197587

sort of interesting how mine only has the one single number on that rectangle and not three like the other transmission in the thread

Re: What can be said about the 4-speed New Process NV833 overdrive manual transmissio
 

more importantly bought some shifter rods off of eBay for $120. Although I only needed the middle one I had to buy all three. At a quick glance they look identical to the ones I have, I will bolt the middle one up here shortly to see how this beauty shifts. Can't wait.

Re: What can be said about the 4-speed New Process NV833 overdrive manual transmissio
 

Cool

Pick the ones with the least wear and sell the leftovers on Fleabay.
Someone is probably looking for them.

Re: What can be said about the 4-speed New Process NV833 overdrive manual transmissio
 

I will wait till I install this transmission and see how it shifts, handles, feels. If I like it I may just keep the extra bits and piece together another shifter. One things for sure, the GM specific truck shifter linkage is more rare than the transmission, ha ha

Re: What can be said about the 4-speed New Process NV833 overdrive manual transmissio
 

so the good news continues, after whipping off 40 years of grease off of the new shifter rod I was able to mount it, and it fits perfect (the seller was adamant it would only fit a 4x4 and not a 2WD like mine) but I did my homework using all three Parts Illustration books you all recommended, thank you and took a chance, well it paid off

please note the small rectangular bracket on ours says 3rd and OD as in Over Drive instead of 3rd and 4th gear like the Mopar ones do, is it more than just text on the metal, does it signify a different cut out / angle for the shifter, who knows, just reporting the facts

I will share pics off all three shifter brackets next, but here is the one I was missing, it's the middle one, fits like a glove

Re: What can be said about the 4-speed New Process NV833 overdrive manual transmissio
 

here are all the three LEVERS as they are called in the parts book, the rectangular pieces that are about 1 inch by 2 1/2 inches, they are not all the same,

the insert cut out for the bolt is on a different angle on each, impossible to see in my pics as it is hidden behind the washer, but I will share some more detailed pics later

also the 1st & 2nd gear one is flat, the 3rd & OD gear one is flat, the Reverse gear one is offset by about 1/8 of an inch

I share this stuff in great detail, in case someone finds themselves needing to make these from scratch, maybe they can make them for themselves, maybe sell them to others

Re: What can be said about the 4-speed New Process NV833 overdrive manual transmissio
 

Make sense since there was some trickery employed to create the overdrive.

Actually third gear is reconfigured to .73:1, and fourth gear is 1:1, so the arm is "flipped" (I'm told) so that you fake the shifter out into thinking it is a traditional "H" pattern. Otherwise you'd have to shift into 4th for straight up and "downshift" into 3rd to get overdrive.

Flipping the linkage makes it transparent to the driver.

Re: What can be said about the 4-speed New Process NV833 overdrive manual transmissio
 

I believe that's specific to the OD version of the A833 not just the GM variant. I've seen 3 of the Mopar A833 OD variants in base model early 80's D150 Ram trucks. They all used the same "flipped upside down 3-4 lever" trick as the GM A833 OD gearboxes. I can't remember whether they were marked 3 & OD on one side or not... likely they were.:D

Re: What can be said about the 4-speed New Process NV833 overdrive manual transmissio
 

here is a better look at the special cut outs in the LEVERS I mentioned earlier

1 & 2 Lever appears to be straight up and down like 12 o'clock

3 & OD Lever is upside down and appears to be angled like 2:00 o'clock

Reverse Lever appears to be angled like 1: o'clock

Re: What can be said about the 4-speed New Process NV833 overdrive manual transmissio
 

I swear I thought something rattlin' loose in that there transmission, I may have knocked something off upon my initial disassembly or it may have been like that from the git go, I don't know, but today I was determined to seek and find it, and so I did

and this is what I found at the bottom of the beast, question now is where do it go?

Re: What can be said about the 4-speed New Process NV833 overdrive manual transmissio
 

Re: What can be said about the 4-speed New Process NV833 overdrive manual transmissio
 

well even with the RIL back in position I still couldn't shift into reverse and I decided the shifter itself was to blame, so I decided to divorce it from the bracket

two bolts, of different sizes

Re: What can be said about the 4-speed New Process NV833 overdrive manual transmissio
 

still not happy that I had to wedge a large flat screw driver to get the darn shifter stick to pop into reverse I decided to take it all apart, it needed a cleaning anyway, as I could hear sand grinding in there

Then Monday Night Football was about to start, so I decided to call it a day

Excellent video on how to rebuild the Hurst Competition Plus shifter, by The Man himself

Which "man" is that?

I was expecting either George Hurst or Jack "Doc" Watson (the "Shifty Doctor").

Sorry to disappoint Keith, he did write the book on how to rebuild the manual transmissions that we see all over the Internet, plus the man has a soul patch, ha ha
