4-spd mount tab repair cost/

I am thinking about buying a muncie 4spd, but it has one of the mounting tabs broken off. How much will it cost to repair this and where would I go to have it done?

Thanky
-Aaron

Sounds to me like a good deal that isn't. You'll have to disassemble the transmission and find someone to TIG weld the ear(s) back on. You may have to remachine it flat and true. Then you have re-assemble. Then you find out all the other problems. I think you can buy new cases now. If it's a screaming deal (like less than $100, buy it and send it to one of the 4 speed specialists.
They can probably rebuild it with a new case. Cost is "whatever".
A good 4 speed is worth about $1,000 to $1,500 these days.

New Muncie cases for '66-74 transmissions (1" countershaft) run about $250-300. I would wonder what else is wrong on the inside. Lots of used and abused Muncies out there... be careful!

I have to ask " how did it get broken?" The problem with welding aluminum is it moves around alot and shrinks. You would need a jig to hold it together while welding, an old bell housing may work. But when your done you still have a used muncie.

Most muncies are well abused ( thats what 4 speeds are for). Any muncie bought used should be torn down, inspected and all questionable or worn parts replaced. The muncies down fall is that the cases are thin and spread under load, the gears mesh changes then they explode!

Muncies are not hard to rebuild. The only special tool need is the front nut wrench.


Like posted earlier a new muncie Supercase goes for about $265. The last time I priced it out you can get a super case, new set of gears, a cast iron mid plate and rebuild kit for under $1000 but you still need a core for some parts.

I hate to say it but I would tend to pass up on a muncie with a busted case unless you want to use it as a core to build up a SUPER MUNCIE !

I had one that had the tab broken off and welded back on and it worked fine. I guess people let the bolts get loose and then the trans tries to turn some and then you have a broken tab. My thought.

I would say its probably the opposite......they get overtightened. A lot of people dont know what a torque wrench is:rolleyes: I have taken aluminum intakes off of engines before that were cracked due to overtightening.

I've seen broken tabs from people that didn't line up the clutch disc properly and drive to force it in by tightening the bolts.
I agree the trans is just a core for parts. Expect to spend about a grand to make a good one out of it. Don't pay too much for it.

Thats it exactly. Back went people were driving these for everyday cars, and people would fix 'em in their backyards you'd see alot of that kind of thing.

I've see them welded, but there's far better alternatives out there now.

Wow I guess when I decided I wanted a Muncie 4-spd I figured it wouldnt be that big of a deal, but I just cant afford the prices you guys are talking about for a good muncie. I would really like a 4-spd but I have always heard that the Muncie was pretty must the strongest but I cant afford it , so what other spd's out there would be strong enough for a daily driven 400hp 383, fit in my trans tunnel without mods, and not shred my wallet to threads?

-Aaron ( a th350 sounds affordable but I love bangin gears:rolleyes: ..)

In the 70's and 80's V-8 Manual transmissions were low percentage of the overall option mix of cars. Not many out there in junk yards anymore. All the collectors and hot rodders have snagged up all the rare M22 Rock Crushers. You'll be lucky to find a Z-28 or Trans Am that hasn't been stripped of the T-10. Junkyard owners know what stuff is worth. Unless you get real lucky you won't find a good one for cheap. Beware of "cheap" 4 speeds. Good deals frequently aren't. Broken 4 speed are everywhere.
Saginaw 4 speeds found in some Vegas and Monzas are relatively cheap but they aren't as strong as a Muncie and good luck finding a Vega. Don't forget you'll need flywheel, clutch, release bearing, bell housing, linkage. Ever priced a Hurst shifter these days?
