Hot Rods GM's manual 3 spd with 5 Mountong holes???

I like to know what I have as well with needing replacement parts numbers matter sometimes. So yes I have a hard on for numbers,LOL

 

Answer is on Johnny Gee's question. My quote back to him.

 

You tell him Jimmy

 

This is exactly why I am a numbers man, need them to sort it all out.

 

Wow your comment comes right out of left field. Who said anything of a "prototype" Not me! Just like to know what I have "that's it" simple....

 

Probably what some of you have been waiting for more numbers and letters.

This set of "Stamping Numbers" and "Letters" I had no idea was there. This is located on main case just under the side cover right lower area, .." S4A19 "... maybe these will tell what it is or its RPO code. Again sorry all didn't see them at first.

 

I have a hard on for Goggle. That's how I found pics to share. It's all good. I went round and round with myself doing the math to figure out a 39 tooth ring gear and 12 tooth pinion. The pinion came back around (home) every 4 turns?

 

Yeah Google isn't working for me on this one (S4A19) just every thing else Not related to Sag. trans.
I think your math is a little off, here's what I came up with, 39 div by 12 = 3.25 not 4.00. Now this is only my opinion but I'd get new batteries for the calculator. LOL

 

^^^^^ Lol, you didn't read the whole problem (math question) completely. But we'll just skip that teaser and stick with yours. Squirrel gave you some info on your other thread.

 

That S means manufactured in Saginaw Michigan, from 1962 to 1979. As for RPO, that was just GM's in house way of saying we're using a 3 speed or 4 speed in any given vehicle. Then next a ratio would be decided by given engine type an L6 or V8 then rear end gear ratio was factored in as a final answer as to what ratio to put into said vehicle.

 

I think i see it now, your a circle car person (NASCAR)
Not real good with riddles,lol

 

Please look at my avatar. If my 56 tried doing roundy round, I'd be sure to loose.

 

I'll give you this much. When I converted my 56 Chevy to manual trans from automatic, I started with a Saginaw 3 speed. Only problem was the 3.11 first gear. That first gear didn't couple well with 4.10's out back. So I drove it using 2 3 only.

 

Not quite clear on what you are looking for, might find the holy grail first.

 

Like I said I'm not real good with riddles or the likes. This pic is me at 19 I think somewhere around 1970. It was my first Tri-5, the others were 55 BelAir 6cyl 3OTT no post, elect windows and seats. My other was a 55 hot rodded one was a 150 no frills stripped down car, this one I used to kick the s h ! t out of Roadrunners (so much for Mo Par) , LOL

 

I see you are not good with riddles ether,LOL.. The very first post of mine is asking for help identifying a 3 spd trans with a 5th mounting ear at the bellhousing to trans mount. Got the picture, lol

 

In order for a question to be answered correctly, the question needs to be correct as well. When has a swallow ever carried a load within it's core? Nesting materiel doesn't count since it's forward of CG factor for which swallow has no idea about nor can it do math to compensate. It just goes with the flow given.

 

Don't count your 56 out as for the NASCAR deal, here are some 56 roundy rounds in history. Oh yeah the one on the Drag strip is my favorite, this one is sure getting a Gripppp As you can see #56 is in the winners circle. look at whats on the rear fender of #56 As Charley Sheen said "WINNING"

 

This is funny, I have one (fifth hole is on top) Saginaw three speed.

 

Have you gotten any good info on yours yet?

 

it's a truck transmission, from 1973 or later.

 

LOL, yes, learned it's a truck transmission. I like it because I'm going to use the shift cover as it has a drilled out boss for a reverse switch. I will place this cover on my '69 Saginaw 3sp+od transmission.

 

Thanks Squirrel, do you happen to know what the RPO code is for this 5 hole trans?

 

did you see this post I made in another of your threads?

I'll give you a little hint here: the info you seek is to be found there.

 

^^^^^

 

If you want to sell to roundy round racers go to racingjunk.com.

 

Also put ad in Craigslist and put race or racing in title.

 

Only those two could pull that one off!

 

Great idea, thanks
