I’m in need of some input shaft advice... and probably an input shaft, or maybe a whole new trans.

I was beginning to restore a short-tailpiece, A833 4spd that came with my project car (1969 Barracuda)... this came to a halt when, over a YEAR ago, I sent the input shaft to Jamie Passon to restore. He then sent it off to someone else to do the work (I wasn’t aware he was planning to do this, or I probably wouldn’t have sent it to him).

The company/Person he sent it to... according to him... LOST it.

He never did find me another one, and I’ve gotten tired of checking in with him to see how the search is coming (I always had to do the calling).... about a half dozen contacts.

Anyway... I’m not slamming him, but I’m tired of dealing with it. So... I have a complete, but input shaftless trans.

Trans tailpiece is stamped with:
PP8333323 (translates to 9/2/1970)

Input shaft retainer: C94796 (4.354”)

I did NOT count the # of teeth on the input shaft before I sent it to him. From my research, I can assume, because it was probably out of a 1971 model A body, that it had 25 teeth, but I don’t know for sure.

Can anyone confirm that I probably had a 25 tooth input shaft?

I’m assuming I can’t just put a 23 or 24 tooth (much easier to find than a 25 tooth input) input shaft in place of a 25 tooth?

Anybody have a 25 tooth IS for sale?

Any other options that make sense?

Thanks!!

Jason

It looks like the one in the pic has 3 grooves in the gear, that is what ID's the gear.
I have a list and pictures if I can find them I will post it.
 
I have an old input shaft I use for a clutch alignment tool, I just checked it, 25 gear teeth.

I have no clue what gear box it came out of & it has some rust though.

Cool, thanks. I remember reading something once about the 3 Lines, too... thanks for looking.

I’ll keep this in mind, thanks.
 
Hopefully you hold Passon responsible for replacing it.
I certainly would, and it may deter him sending other peoples parts out to whoever it was that actually lost it.

In fact, you shouldn't have to do this, as they should take it upon themselves to replace it.
 
This is why I use it for a clutch alignment tool;

If worse comes to worse........ send them the photo of mine above to see if they think it can be saved.

Jamie said he would replace it. He was pissed at this company and so I think he stopped working with them. But months would go by and he’d never call me... I’d call him back and he’d say he hasn’t found one yet, etc... He’s saying the right things, but I’m pretty done with waiting.
 
What ever you pay for the replacement, charge Passon's double, the other half will cover your pain, aggravation, & time searching.
 
Pack the remnants of your transmission, send it to passon as a core and have him give you a break on an exchange unit, or better yet, they have complete transmissions listed on their website, tell them to pull an input out of one and send it to you.

They should be bending over backwards to rectify this.
 
I just picked up a 25 tooth from a guy in Alberta Canada. I can't remember if he had another or not? PM me & I'll give you his name and cell number. My gear had 3 cuts in the teeth as well...

I would put that in a ultrasonic cleaner and see how it comes out, I have a 1/2 gal and a
2 1/2 gal unit and you would be surprised on how a little rusty part cleans up.
 
Hang on, that 25 tooth is special; it comes out of the close-ratio T/A box
The ratios were 2.47-1.77-1.34-1.00 with splits of .72-.76-.75
The cluster should have 30-26-23-17
That trans was only built for two or three years.
Because first gear is so high, it usually requires about 10% more gear to get moving; for example , if you had the regular box and 3.55s, your starter would be 2.66x3.55= 9.44.... and 9.44/2.47= 3.82s ;rounds up or down to 3.73/3.91
A replacement M/D is gonna be hard to find, and nothing else fits. :(
_________________________________________________________________________
I tried this box in my streeter and found it unsatisfactory with 3.55s cuz the starter was only 8.77 with 3.55s; and my combo likes 11/1(3.09 x 3.55). I did like the splits tho; great for a small block, and excellent with 4.30s...... but that puts hi-way use on the back-burner...... at least for most of us..... and I live 20 minutes from anywhere, all hiway.

Good info...I have this same trans(73 vintage) I am currently putting together. I am using 3:73 rear on my 69 Swinger 340 so by the sounds of it I should be ok?? I read a chart that gave me a spec of around 3100 rpm at 60Mph. Does that sound correct to you AJ? Thanks

Yeah I get that. Why did Passon have it in the first place?

We talked on the phone about a rebuild kit, etc... then he wanted to see pics of my input shaft, which i sent to him. He looked at the pics and said he could recondition it for me, so I sent it off... knowing he had a good rep.
 
I ran mine w/3.91 and 28" tires and it worked great, was still looking for that other gear on the highway though.

Looking at the picture you posted of yours I don't see any thing major league wrong with it.

That combo will give you a starter gear of 9.21; a little tall for a 340, but you're a couple of hundred pounds lighter than my S-clone, so , depending on the rest of your combo,it should be OK. At 3100 your tires would have to have a roll-out of 76.24, or about 24.26 tall. That's a pretty small tire; Like maybe a 215/60-14 . You probably wouldn't want to run something that small on a 340car.
More likely you'd run a 245/60-15 @26.7" tall, and rolling out at 83.9 inches. This would get you 2817@ 60 and Zero-slip, ie with a manual trans.
But really, with a 340 you should be running the tallest widest tire that will fit, on a wheel well-centered in the tub, whatever it takes.
And I'll tell you why; cuz if you don't,and if you run a DP carb; there's a VERY good chance, that she'll be sideways at the oddest times, and pointing backwards some of those times.Don't ask me how I know, I'm 65 years old and learned to drive in a 70 Swinger
That taller tire will throw your speed-O out about 10%.... and it will make starting out require a bit more rpm than before.
I run a 27 inch tire,with an HO 360, and wouldn't want anything less than a 10/1 starter gear. We'll see how your 9.21 works out. If you got a 292/108 cam Then you're gonna want a whole nuther comb,lol
