Is it a Saginaw or muncie? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

LandonL · 08-01-2010, 03:24 PM

This was sitting behind an inline 250. The truck it came out of was the bare stock no optioned truck of 67. Im leaning towards saginaw, but would like reassurance before I buy a rebuild kit..
4 bolt side cover, it's a 3 spd.

i believe the saginaw were 7 bolt and muncie were 9 bolt but not 100%.
someone else will for sure know.

Livrat · 08-01-2010, 04:11 PM

It is not a Saginaw.. that is the factory GM trans (last used in 67, not sure if it was called a Muncie or not)

Heres a link to a Saginaw pic

That's a car tranny.

LandonL · 08-01-2010, 04:22 PM

Oh, well I was completely wrong then. Do these normally sound like a meat grinder in second? Anyway, where can I get a rebuild kit for it.

mbgmike · 08-01-2010, 05:04 PM

I think they are called the V4S

basemodel67 · 08-01-2010, 05:20 PM

Nope, not a Muncie or a Saginaw. I think it is called a POS!

That is a dinky gearbox. Kinda reminds me of those old boxes behind flatheads. I don't think it would hold up to much power.

x2. here is a link for parts http://mmerlinn.com/catalog/papercli...s/gmv4s010.htm

LandonL · 08-01-2010, 05:18 PM

Know where I can find a manual or any information on it? Looking for a rebuild kit also.

LandonL · 08-01-2010, 05:28 PM

It may be a POS but its going back in the truck, I don't have the funds to upgrade trans's atm.

c1069 · 08-01-2010, 05:36 PM

I found this link, I hope you find the information you're looking for

LandonL · 08-01-2010, 05:37 PM

I think it's a GM-V4S-01-01TR-90
The case number matches up to the one listed on this page http://mmerlinn.com/catalog/papercli...s/gmv4s010.htm

Now where in the hell am I gonna find a kit to rebuild it lol

LandonL · 08-01-2010, 05:49 PM

Im looking for an entire kit, I might give that guy a call.

mr.chevy · 08-01-2010, 07:41 PM

Never seen a trans that looked like that before. Does it cost more to rebuild than its worth?

mr.chevy · 08-01-2010, 07:46 PM

Ya know i bought a new process 833 3speed with an overdrive for like 100 bucks and its proving to be an easy conversion except i need a new drive shaft well shorter. i am only saying its an option.

Actually the NP 833 is the same length as my old saginaw. I didn't need to change shaft. Just a bigger hole in the floor for the shifter. OD with a 2.76:1 rear means 55 mph at darn near idle! I Love It!

That sounds nice. I have 3:73 in the rear now and i haven't got that NP833 in yet but its a lot longer than my muncie sm 460 with the ultra low. I use to have the muncie and 5.13 in the c20 rear before the switch to c10 stuff.

LandonL · 08-01-2010, 08:55 PM

It's got the three on the tree setup, and switching to an automatic= $$ and a hole cut in the floor. Are there any 3spd manuals that bolt up to the existing three on the tree setup?
If I did decide to go the 200R4 direction what ALL will I need, I do think the radiator has line hookups for cooling.

*72lb4x4* · 08-01-2010, 09:20 PM

Got any pics of the removable lower part of the bellhousing? Maybe a casting number?

LandonL · 08-01-2010, 09:48 PM

I don't have any pics of the bottom.

dwcsr · 08-01-2010, 10:19 PM

Its a Muncie SM318. Kits are still available for them. You won't find syncro rings and the sliders are hard to come by. You can find low reverse gears and reverse idlers on ebay but they are a bit pricey. Try http://www.mackstrans.com/ for the kit. I get kits from them and they have reasonable prices. The bearing kits are almost all the same, its the gears that can very greatly so you need to know what year and model it came out of.

LandonL · 08-01-2010, 10:47 PM

How can I be sure it's a Muncie SM318?

dwcsr · 08-01-2010, 10:48 PM

It may have been in some cars but its the same transmission that was in the 55-66 or 7 Chevy 1/2 tons. Cars had a rear support cast into the tail shaft

Sorry! With a real quick glance it looked like a 60's passenger muncie 4spd. It's getting late. lol
