What can be said about the 4-speed New Process NV833 overdrive manual transmission?

Not sure bud, but could you take a picture of the way you have the guts aligned before you put the cover back on, in particular where is the reverse gear thing supposed to be. I am only able to shift 3rd and Overdrive gears I can not shift 1st and 2nd nor reverse, and this is by hand without using the Hurst shifter, so I know its not the shifter, and I know they are supposed to shift with an adjustable wrench or by just pulling and pushing on the rods by hand.

[Gregski]

can anybody help me figure out how to keep this Reverse Interlock Link from falling out, more specifically the pin that it pivots on, which sits in a hole in the side cover.

the design of it is completely illogical to me, its like hammering a nail into an existing hole, there is no anchor for it if you will, is something supposed to go into the notch in the bottom of the pin?

[walkerb]

That where im at also. Gotta be a way to move/position the forks so that something, anything!, holds it. I wonder if we can use a dap of heavy grease to hold it till its installed?

I'm ordering my cover gasket today so that i can get this swap moving!

[Keith Seymore]

I can't say for certain but I wonder if that pivot is supposed to be "peened" over.

Hi Keith thank you for commenting, could you elaborate on what you mean by "peened" over please, I am not sure I am familiar with the term / process.

Yes - basically it's a fancy word for "smashed all to Heck".

As in "ball peen" hammer - you use the rounded side of the hammer to fold enough material over the side of the post/stem such that it holds the other part in place.

Almost like taking that post and smashing a head onto it, turning it into a sort of free form rivet.

You can disregard all this, though: it didn't realize the head was already formed and that your were pressing the stem into an existing hole.

Is it held in place during operation by some other feature on the case?

Could you hold it in place with blue or red Loctite during assembly?

finally pulled my SM465 Muncie out to compare it to the New Process (or is it New Venture) 833

Clearly the 833 is longer than the Muncie, though the mounting brackets appear to be fairly close

[Gregski]

trying to offer up some better ways to get the measurements to be more meaningful

The Muncie seems to be 18 inches from where the bell housing would butt up to the front and to the center of the universal joint

The 833 is 21 1/4 inches from where the bell housing would butt up to the front and to the tail end. It uses a slide in yoke and not a fixed one like the Muncie

[Gregski]

and lets take a look at the bell housings, in my case both the 833 transmission and its bell housing have a dual bolt pattern, so I can use my old bell housing if I like because the 833 has a bolt pattern that will already match it, NOT all 833 transmission are this way (I think)

[MalibuSSwagon]

My C10 with SM465 actually has the duel pattern bell installed factory.

It's pretty much the same aluminum case NP A833 Dodge used in the Ram trucks with a GM input shaft and output spline count.
Make sure the countershaft plug seals properly and the countershaft isn't rotating in the case.. And don't use gear oil in it...

Thank you, but what do you mean "don't use gear oil in it" than what should I use and why?

The aluminum case A833 from the 80's used Dexron III... Gear oil is too heavy. The rumor is they changed something and you'll burn out the countershaft needles. Best case the heavy oil makes it shift strangely and use more fuel.
You can't use Dexron VI in them according to GM.
The GM 88861800 fluid is cheaper than the Mobil ATF "Dexron III compatible" fluid that lists compatibility with GM 88861800 on the back label.

Bulletin 04-07-30-037E: Release of DEXRON-VI Automatic Transmission Fluid
"Any vehicle that previously required DEXRON®-III for a manual transmission or transfer case should now use P/N 88861800. This fluid is labeled Manual Transmission and Transfer Case Fluid."

You can't use Dexron VI in most power steering applications where you could get away with Dexron III either... OTOH There's a TSB for my Impala and several other mid size GM cars from the aughts that says to replace the power steering fluid with Dexron VI... Roll with the changes and try to keep up.

so decided to cut out the stick out of my shifter bottom end assembly for two reasons

1. the threads for the ball were broken off on it anyways

2. I did not like the hockey welded in install, even if it was factory

[Gregski]

this is where I noticed something was not as expected, my shifter (our shifters) do not have the two bolt holes to hold the stick in the bottom end assembly, that's when I went Def Con 4 on the InterWebs to do some research, and here's what I've learned

HURST makes at least two different types of bottom ends, the Bolt-On style, which is what most of us are familiar with and the ones we got, which are called Slip-In style

found this pretty cool installation page for them, but looking at my stick I can't wrap my mind around what keeps these sticks from falling out

[Gregski]

and here is a comparison of the Bolt-On style HURST shifter bottom end assembly (the one with the two holes) compared to the one like ours aka the Slip-In (no bolt holes)

images from HURST Shifters Online website

[Gregski]

these are the rubber isolators and metal clips required to hold our sticks in place in the Slip-In style

again since GM decided to weld in our sticks I am not sure if they had the proper holes or notches in their bases to actually utilize these clips, maybe they didn't and the weld in was a work around

[Gregski]

I think there are actually special Slip-In sticks that are to be used in the Slip-In bottom end assemblies, but the only one I could find on HURST Shifters Online website was this one for a 1970 Mercury Cyclone Ford Torino

Hurst 4 Speed Slip-In Shifter Handle, 1970 Mercury Cyclone Ford Torino

note the single hole bottom end design

Correct. The bottom of the shift handle snaps into the shifter base with no tools, for ease of assembly. There is a notch on the stick that corresponds to the retention tang on the clip.

Incidentally, the guy that installed these shifters on the assembly line, as well as the M20 shifters, worked for me when I ran the Fender Set area. He also installed the cab running lights and the SPID label.

My handle does not say "Hurst" on it, which is probably why you don't find them when you search (most sellers probably don't know it is a Hurst stick).

Well Gentlemen the Greg has some Great News!!!

today after work I swung by a fantastic transmission shop Manual Transmission Warehouse (2 miles from my house, I kid you not)

and Larry hooked me up, what a great man! I went in there with my case and said Larry how in the world is this pin supposed to hold this reverse lock out bracket if it don't go all the way through the side cover

and Larry looked down at the floor where we was standin' and picked up the same lid from another transmission just like ours, not a Morpar 833 but one fro GM and said "Well hewk lets take a look"... then he asked "what part number is yours?"

his said C-13550-2

mine just said C-13550 (no 2 at the end)

clearly his was a second revision part, more importantly on his the pin went all the way though the side cover, on mine it did not
