Re: is it a muncie or saginaw

On that Mr. Gasket link there is a picture 341 chevy transmission. That is likely the trans that Brad had, it is not a muncie or a saginaw, it is a chevy trans. They are very weak, weird internals, and non sysnchro low and the were used thru 67. 68 and up should have either muncie or saginaw unless swapped out sometime.

Re: is it a muncie or saginaw

Green Machine, except for that long tailshaft housing mine looked similar to that. But that tailshaft housing is confusing me if that's what I had because mine was much shorter than that. That drawing could be misleading and out of perspective. My 'Muncie' definately had 4 side bolt covers, was original to the truck and had a non-syncro 1st gear. I hope we can get this all straightened out once and for all because I just sold this and I'd like to inform the guy if I mis-stated what I had.

This is a weird thread- it used to be so cut & dried figuring out what was what on here, lol. Now we're all second guessing ourselves, lol.

Re: is it a muncie or saginaw

10-4 on that. Yep that pic had a weird long tailshaft. I still would bet money yours was the little light duty type. Used from about 55-67 iirc. Long distance troubleshooting can be very tough sometimes. But I reserve the right to be wrong too

Re: is it a muncie or saginaw

Here, guys....here are some pictures from when it first came out AND very, very close up shots of the casting numbers and crap like that. If this isn't enough to ID the tranny, I don't know what is.

NOTE: The first picture linked up here is LARGE. (~400k in size), so dialup users beware.

Re: is it a muncie or saginaw

Oh - those numbers on the side of it....

On the tailshaft: 3911984 GM 5
On the non-bolted plate side: GM 2 E271 8987948 (B987948? 3987948?)
On bolted plate side: GM2 3952648 E271
Tag on bolted plate side: 3968081QY (396808IQY?)

And one last tidbit of info: This SOB was wound the hell out in 3rd gear when hooked up to my 3-on-tree. I could only do 65 with it running 5k RPM at 65mph with my 3.73 gears. I hope this helps?

All the numbers I am looking up online keep saying this is a Muncie 4spd, but ... I don't believe it.

Would the shift linkage linkage have prevented me from hitting the 4th speed?

Re: is it a muncie or saginaw

Jason, it doesn't makes sense that you were wound out in 3rd gear with a 3.73 rearend UNLESS this was a 4 speed. On a 3 speed the 3rd gear is 1.00:1 and you'd only be doing around 3000rpm at 65 with a 3.73 rearend.

Re: is it a muncie or saginaw

I should clarify It "felt" like I was wound out around 5k RPM. I definitely could not go faster than 65 in the truck or it sounded like it would blow up (3spd+that tranny).

I looked at all the Muncie 3spds, my side cover plate doesn't look like any of them. I actually can't find a dang cover plate that looks anything like mine and the one above - the muncie and saginaw that look alike have one bolt in a high middle position - like the one with the side cover off that you posted a pic of above. however, neither of these two trannies have that.

i'd love to know what that tag means on the side of mine. i feel like that is some RPO code or some other indicator to tell what the heck it is.

Re: is it a muncie or saginaw

With respect to your trans... that is definitely Muncie as many have stated previously. The fastest way to ID them is the 2 top bolts for Muncie and 1 bolt top center for a Saginaw. Is the Muncie tougher ? Many people think so but they don't bring much when compared to the Saginaws.

I am an auctioneer as well as a fire fighter and we just completed our first racing auction last weekend. We'll be doing several of them throughout the Arkansas, Texas, Oklahoma and Kansas region in the coming months. We sold 3 speed Saginaws at auction for as much as 100.00. The Muncies brought a max of 50.00. The Saginaws are very popular iin the dirt track world and finding those without broken "ears" is what makes them so valuable. There are some racing trans companies out there who will pay 100.00 flat for any Saginaw with ears intact without regard to the inner workings. Hope this helps you decide not to throw those old " bad " transmissions away. Dean

Re: is it a muncie or saginaw

What is an "ear"?

And, by all means, which Muncie is this? Like, what is the model # on it? How many speeds is it? Any other info you can provide?

Re: is it a muncie or saginaw

The 'ear' is the part that bolts up to the bell housing.

Re: is it a muncie or saginaw

Wow, trying to get a definitive answer (model # of pictured trannies above) is like trying to find out how many licks it takes to get to the center of a Tootsie Roll Tootsie Pop.

I can't find a model number and the side plate doesn't match the bolt pattern of any Muncie I have ever found anywhere on the internet.

Re: is it a muncie or saginaw

Betcha it's a 351 Muncie. It should have a syncronized first gear. Look at the spacing of the shift fork shafts and the extra cast bosses on the cover plate.

Re: is it a muncie or saginaw

The bolt pattern is roughly the same, but the drain plug and the side cover is a diff't shape than what is pictured in the Mr Gasket PDF....linked in a post above.

Re: is it a muncie or saginaw

Hey shifty somewhere around the side cover you should find some numbers stamped into the machined surface of the case. The pic shows you where i found mine.



now that stamp should tell what exactly you have once take a look at this web page---> http://www.novaresource.org/trans.htm

I think that should help you out

Re: is it a muncie or saginaw

The bigger all-synchro Muncie 3-speed was the heavy-duty option in cars when the Saginaw was standard equipment. My sister's '69 Camaro SS came with the Muncie, and it was surely heavy, especially resting on your belly after her clutch went SPROINGGG.

Re: is it a muncie or saginaw

Muncie 3 speeds was an "Heavy Duty" option for passenger cars.

Re: is it a muncie or saginaw

65-68 was a Borg Warner HD 3 speed (T16) and 69-72 was a Muncie HD 3 speed (MC1). The diagram here is typical for the T16 shows the correct tail section for Shifty. But according to the cast numbers on the side cover Shifty's transmission is a 71-72 Muncie and Crazyred's is a 69-70 Muncie

Re: is it a muncie or saginaw

Interesting. The Mr Gasket PDF shows the T16 with a 9-bolt side cover. I have had two different people tell me that it was probably a Muncie MC1 or M13 at this point (@ another forum), but ... that's the first definitive proof I've seen that it could be anything else.

Thanks for the link, Fenny.

It's possible this is a T16 made in '68 and could have come with the truck, I guess. I have tried time and time again to find anyone with extensive pictures of various trannies on the web, and nobody I've found does. Nobody pays attention to truck trannies, only the SS cars and whatnot.

I think you may have misunderstood me. I am agreeing with you that it is a Muncie. The diagram in the link is for the T16.

That link is great!
But I'm still a little confused as to what I had in my '67. It had 4 side cover bolt holes I think, with a number of M7M15. The 3 speed listed above has 7. The 3 speed Saginaw from 55-65 looks similar but it appears to have at least 5. So personally, I'm still at square one trying to figure out what the heck my truck came with from the factory. I wish I still had a picture and I just finally sold it about a month ago now.
I'm so happy with my new T-5!

The diagram in the link you sent says "Correct for MC1, 'typical' for T16". I think it's a diagram of the MC1, so I agree I think it looks like an MC1.

Sorry, here:

http://www.teufert.net/trans/trannyid.pdf

I think that is where Mr Gasket got the images (if not, it looks exactly the same!) The T16 is listed in there and has a 9-bolt side cover. Looks nothing like what is posted in the PDF you linked, for whatever reason (I think that's why it says "Typical" for T16).

I'm going to look for the casting number mentioned above - on my way home right now. Maybe we can put this to rest once and for all

Look at the PDF I just posted...look like any at the end of that? The Chevy 341, 342 and 344 looks like they have a 4 bolt cover
