Thoughts on a new supe rcase muncieM22/wide ratio

[crazy longhorn]

What do you all think about that M-22 Muncie super case, with new Italian gears? I am looking @ a wide ratio box, to replace the Richmond trans....dont need the OD , with the 3.42 gears. I love the gear whine, no issues Longhorn

[jjzepplin]

Would like to see one. Do you have a link?

Found this.there's mention of maserio gears.http://www.autogear.net/motorsports/

I have had 2 of them . One was there version of the m22 2.20 first gear . I pounded on that thing and it never missed a beat . They came out with some other gears so I got there new m23z. It has 2.98 first gear and allowed me to get rid of the 4.56 rear gear and put in a 3.73 and still launch the car .Also It allowed me to be able to drive somewhere . This is all in a 67 camaro ls2/ls3 ported top end carbed motor 600+hp .

There is several gear combos now to choose from for your needs. These trans are strong .This is what GM should have built . George at AG was great to work with . They can build most anything you need .

When I ordered it and told him what I was going to do to it he basically said let it rip . The other nice thing is both of mine shifted smooth with out any hiccups .

They have really made improvement on these trans .

Longhorn , As you said these m22/m23 do whine but not a problem for me as well . In 4th gear the trans is a 1 to 1 so no whine there while cruising .

Here is the gear choices now .http://www.autogear.net/wp-content/u...se_modular.pdf

I've been giving a lot of thought lately to replacing my 3 ring saginaw with the M22z. The Saginaw has the really low 3.50 first and I use a 2.76 rear. It works good for a cruiser, but many on the net say the m22z with a 2.98 first is perfectly suited for a 3.08. (Which I have laying around). Everything I've read indicates that the new Muncie is a stout tranny and cleary more economical than going the TKO route.

Any idea what these are costing?

As for a picture google autogear muncie picture and you will see it looks basicly just like the old muncie trans .

Cost is going to be 1700 to 2300 depends on what you get . There is a price list on the link mongocanfly posted . Just have to dig around for it .

Also just to warn some that there is a lot of people buying parts from autogear and building trans and calling them autogear . You will see alot on ebay . They are not a trans that is build by the Syracuse people . There is a couple builders that build there own with there performance twist to them that would be fine . For me I bought mine direct . Also for warranty purposes .

I love my trans and would buy another .

[crazy longhorn]

Thanks guys! The trans, seems to come in around the price of a Richmond T-10....but looks to me to be MUCH better built. I might miss the OD ratio, on the hyway....but dont run there that much? A 3.42 gear/29" tire will still cruise pretty easy @ legal hyway speeds & still have a fairly rowdy cam into the "sweet spot" Longhorn

[crazy longhorn]

Just another question.... I have done the read on 2 different shops. Auto gear is the 1st , & 5 speeds .com was the next. Paul Cangialosi, has several U-tube videos out on the build. He talks about using the super case & tail, with his own billet steel rear bearing support,italian gears, & no rock sliders (Syracruse NY). Any thoughts on either shop? Longhorn

Both of those shops are fine . Paul does his own twist to them like fine tune the sliders so they will slide smooth as silk as well as some other things . I think he has a video on this if you have not seen it on the slides . Auto gear is the maker of the parts and does there own builds . They do a micro polish on there m23's and is available on other trans . The micro polish gets you past the break in period with out some of the notch feel and makes them slide smooth when new . Both of the ones I had shifted smooth at any rpm up to 7000 . You will spend more money on Pauls trans but he does do a lot of extras to his . I would like to have the sliders he sets up in mine but I have not deemed it necessary in the auto gear trans .

Just to add a note to your previous post . I have a 28" tire 3.73 gears and cruise at about 2700 rpm at 60mph . With my healthy cam this motor likes it with no problem . A 3.42 with 29" tires should be some where in the low to mid 2000rpm

[James the III]

3.42 and 29" @60 is 2377rpm

I'll be buying a supercase soon as my front bearing support is loose on my current M20. Heard nothing but good things about these guys.

Thanks for the "heads up"....I rebuilt those old Muncies, way back in the day(before they were worn/stretched out). Pauls vidios really impressed me, & I think that may be the route to go! Again thanks to all for the info ... Longhorn

[AcampoDave]

C.L....if you buy one, I'd really like to know how it works out!

[AcampoDave]

Did you ever buy that Muncie C.L?

[crazy longhorn]

No sir.....kids /grand kids, & home repairs , have kept my buzzy! I also have a new (to me ) driver truck, pretty nice 2014 Z-71, with 31000 miles. My cash is tyed for a while....if you try the trans 1st, post back! IMHO, Paul showed the build, & that would be the way that I would go longhorn

[jjzepplin]

These things look mean. Are they stronger than the TKO? Sure would like strength and overdrive!

[homemade87]

I cant say about the TKO , but I can attest to the autogear trans . I have been beating on them for a while . Foot to the floor power shifting and never let up going thru all the gears . I must say by the time I get to 4th its time to let up . Never miss a beat at 7000 rpm shifts.

Most will not use there trans like I do . Autogear says no problem and I have proven this . If you are using street tires you will most likely not put the trans to the limits .

As for overdrive . There is many gear selections now that will allow you to run something like a 3.08 gear and will give you some good drive ability and cruise speed .

In the end it depends what you want to do and your end goal . My end goal was to go fast in a short period of time reliably . I run the M23z

[jjzepplin]

Rightl then. Hmmm. My 66 Chevelle had a stock rear. I'm guessing it was a 3.08 and a close ratio M22 with a stout 350 and that thing was unstoppable. SO maybe I have to ditch my 3.73s. I guess I will try them out first. It's only a Saginaw in there now so I will mess that up while saving for either a TKO or Super Case. The Muncie would be an easier swap so Maybe that way.

[homemade87]

Reason for the 3.73 or higher ratios was the m22 has a 2.20 first gear . Very hard to get that thing moving with the 3.08 . It will feel like you are starting off in 2nd gear , but great for for cruising .

The new autogears does have a 2.98 first gear . In mine it has a 2.22 2nd gear . Nearly the same as the original m22 1st gear . With the 3.08 to 3.42 ( depends on what you like ) you will have a much better take off speed but still have better cruise speeds . There is several different ratio sets to choose from now .

If you are a muncie now you will definitely be an easier swap . The trans is 3/4 to 1" longer so you maybe have to shorten the driveshaft . And a couple more tweaks . A lot less than a TKO .

I hope crazy Longhorn dont mind us chatting in his thread .

[jjzepplin]

Me too! I just wish the Muncie could have an overdrive-ish 4th gear. By the time I get to 4th I need something more than 1-1.
Sorry Crazy...

[AcampoDave]

https://www.5speeds.com/newm22.html scroll down a tad to view the various ratios available. I still haven't got one yet either. Got me a new roof on the house instead.

[crazy longhorn]

Guys, you are 'busted", for chatting on this thread No issues, this crazy old man can still learn from the younger guys I just want all to know....I do not know Paul, & not have ever dealt with him? I have however, rebuild many old Muncies (back in the day), & what I see on the vids really impress me that he is building "right on"! Longhorn

[jjzepplin]

Sooooo, How do you like your Richmond 6 speed? Durable? That longhorn sounds like it isn't short on anything...Linky to pics?

Good advice there. I just went through the grief of M21 then M20 and finally DN 4+1 (3.27 1st) on my 68 C10 Previous setup was 700R4 and proper gearing is critical on standard shift to get the weight moving. My gears in back are 3.08 which were fine until I got away from automatic transmissions.
