Anyone know where i can get a new one? i have a 88gt with a 350, i think mine is slowly kicking the bucket, and i want to get a new one and put LSD in it. Anyone have a new one kicking around of info about how to do the lsd i would greatly appreciate it. Thanks
Prox

Goodluck, mine has only 54k on it and a cracked housing that I've jb welded cuz I couldn't find a low mileage one or one in general

damn lol its gonna be a struggle i know it already lol

look in mall. guy wants $3500 but it is "built up"

I do have a stock 5-speed Getrag for sale from my '88 Formula. It is not new.

I had another Getrag rebuilt and had a Gr8Grip installed in the differential by Bud Adelman of Bud's Out Back here in Tucson. I intended to put that trans with the Gr8Grip behind my 350 enhanced GT, but am now using a 6-speed. The Gr8Grip rebuilt went into my Formula and the Original Formula trans is for sale. Shifts very nicely. If you wanted to buy it, and wanted it reinforced with a Gr8Grip, I could get you Bud's contact info.

why not swap to a beretta FWD trans? there easier to find.

PM fieroguru. He ran a fresh-rebuilt one from ManTrans with his 350.
The limites slip comes from www.engineered.net, they have street and race versions.

At one time Mera7 was offering a fully rebuilt unit, with cyrogenic treatment, and I think LSD might have been an option.

This is what im really looking for lol. Everything down to a t :P

Can I hijack this thread for a minute? What causes these cases to crack? Is it from people doing burnouts off-idle? Or is it high-rpm shifts?

I know dropping the clutch can have a major impact on a transverse transmission, which is why I personally won't do it... but just curious if running it through the gears is also partly the problem? I wouldn't imagine that it would have as much of an impact?

Broken or bad motor and transmission mounts. The motor goes one way and the trans goes another. Somethings got to give and most of the time its the aluminum of the transmission.

www.mantrans.com is a source for rebuilt transmissions...

what is the difference between mt-40035a mt-40035b mt-40035c.
there for different cars but what exactly is the difference?

Was wondering the same

also

My Pontiac Fiero repair manual lists the two 5spds as the Isuzu and Muncie 282, Muncie and Getrag same trans? I did find some muncie 282s on ebay a few weeks back wasnt sure though posted in a thread about it and someone said they were different trans and that it probably wouldnt work, I thought they were the same though

The Fiero came with at least two different 4spd Muncie's a HWY econo trans had like 3.30 gears? Then the 4:10's in 84. All muncies were 4spds.

As for 5spds , there was the Izuzu, and 3? different Getreg gear options. Thats probally what the differences are.

speedometer gear. One has a gear driven one, one has a magnetic impulse one and not sure of the last.

I also had called Mantrans in the past. It was ~$100 for shipping. The ~$900-1000 is about the same prices I have discovered from other transmission rebuilders.The extra getrag I had, I donated to another Fiero enthusiast who needed one, deciding that I have two Fieros with good getrag transmissions and that my need shouldn't become a need in the future. Why I looked into Mantrans was that I could deliver it myself as Talahassee is less than a days drive.

quote Originally posted by Custom2M4: 5spd options; "The Getrag 282 5-speed is sometimes referred to as the Muncie 282 or the Muncie Getrag 282, as the design was licensed to General Motors for manufacture by Muncie (Getrag never built the 282)." Two Options; 3.35 (MT2) or the 3.61 (MG2)

The MT2 is the Isuzu transmission

The Fiero vintage getrag is getting hard for the rebuilders to come by... that is why many people are upgrading to the 89-92 versions with the internal release arm or the 92-94 HTOB getrags.

For about $1200 you have have a rebuilt 92-94 HTOB Getrag shipped to your door and that includes paying for the core vs. sending one in.

The V6 5-speed used in Fieros is a "Muncie 5-speed"
It was designed by Getrag and is usually called a Getrag, so either Muncie or Getrag is correct. Many parts listings will simply call it a Muncie 5-speed with no mention of the Getrag name.

There was also a Muncie 4-speed, so make sure it's talking about a Muncie 5-speed, not 4.

The other 5-speed transmission is made by Isuzu and was used only on the 4 cylinder.

If you could really find a new one, probably for its price you could swap a real new 6-speed unit that will be stronger. Something to consider.

Are the 6 speeds really that much stronger?

How much would it cost to have someone swap a 6spd in? Where do you get an adapter plate to bolt the 6spd to the fiero engine? Because I need to get my clutch replaced in my Formula BUT the Getrag case is cracked and I didnt wanna go through all the trouble to pay someone to put a new clutch in and still have a garbage tranny

the tranny itself isn't costly, ist all the components you need to go with it that are....not worth it in my opinion....you will need anywhere from 1500 to 2000 grand, depending on how resourceful you are

quote Originally posted by PR0X: Are the 6 speeds really that much stronger?

Yes and they are not too expensive on Ebay. I think the cost will be in adapting it....but I may be wrong. I believe they are rated closer to the 300hp range. The G6 that they used them in put out 240hp.

Well to take my fiero in and have the clutch replaced I'm lookin at probably a grand right there, thats why I figured for the extra 5-700 it'd be worth the swap, Any companies making plates to adapt them to the fieros? or is it all local fabrication shops?

It would be a great upgrade but what ever you think your going to spend on the conversion which is 1500-2000 times that **** by 1.5. So your looking at about... 2250 to 3000$

thats the one i found about 2months ago and asked if it would fit on here and someone said no they didnt think so, but it should fit IMO

As is it won't. Just look at the bellhousing. I think is the Quad-4 type. But I have heard that the bellhousing can be swapped with the Fiero type. Regarding the 6-speed, if you have a FIero that you will keep forever and needs a trany I think it is a great investment. Plus you may buy an extra spare for the future. At least I did

You put a 6spd on yours? how much did it cost and howd you adapt it?

also how can they sell the NEW 282 for only 400? Is it built by a foreign company to spec of a 282? Cheaper/Weaker quality?

quote Originally posted by White88Formula: also how can they sell the NEW 282 for only 400? Is it built by a foreign company to spec of a 282? Cheaper/Weaker quality?

The description says it all:

**BRAND NEW** MUNCIE HM282 FRONT WHEEL DRIVE 5SPD TRANSMISSION.

THIS TRANSMISSION FITS THE QUAD 4 ENGINE BUT WILL ALSO BE AN EXCELLENT UNIT TO USE FOR REPAIRING YOUR ORIGINAL MUNCIE HM282 AS THESE UNITS ARE BRAND NEW OEM - DIRECT FROM NEW VENTURE GEAR. And as far as I know, NVG is still a U.S. company (the transfer case plant is here in Syracuse).

I reason I believe it's so cheap is that it's for the Quad 4, which in my eyes, is not a very desirable engine. So, I think the trans is a hard seller because of this reason.
The bell housing can be replaced with a Fiero specific one, using a Rodney FWD kit, and changing the speedo gear, it will adapt for Fiero use. I have heard the gearing isn't the greatest, but I don't have any First hand knowlege. The one good thing is that it has the larger Diff pin and spiders in it which are stronger than the stock Fiero parts. And can be used in the Fiero specific trans. -Jason

Archie sells kits to adapt them. I used the one for my V8 application.

The final drive is 3.94 on those ebay transmission, not the fiero 3.61 - and most people looking for new transmissions are people with engine swaps and the 3.94 really isn't suited to anything but a DOHC engine.

Also, these are HTOB transmissions, so you can't just swap in a fiero getrag bellhousing, you have to swap over one of the shifter shafts as well.

The majority of people who have purchased those transmissions mainly used them for parts for another getrag.

Help me out here: Why would you have to worry about the clutch release shaft, if it's built into the bell housing itself? The HTOB also has it built into the housing as well, simply changing the bell housing portion would solve that problem...or am I missing something. I've had plenty of 282's apart (Fiero and fwd) but, have not come across a HTOB yet. But, by the pictures I've seen, it should change over with out an issue.
The final drive I know about, which is why I stated that in my original post. I also know very well about the shift shaft issue (it's approx 1/2 shorter than the Fiero's), which is addressed with Rodneys kit.. And the shaft can be easily changed out to the proper Fiero one if, you know how to disassemble the trans.
No flames intended, heck I hardly post in tech. But, I thought I knew the Getrags (muncies) well enough to provide some useful advice about them. You see, I have them in all my Fiero's and have serviced them internally as well as a few for other people. I'm just looking for more info....-Jason

The clutch release cross shaft on the non-HTOB getrags is recessed into the bellhousing case and so one of the internal shifter shafts (I am not talking about the same shaft that needs replaced to use the Getrag shifter brackets vs. Rodneys FWD brackets, but another internal shifter rail support shaft - I think it is for reverse... been way too long since I have had it apart) is supported at the bellhousing case with a bolt on plastic cup.
The HTOB bellhousing case was not recessed for the clutch release cross shaft, so this internal shifter shaft is longer and is supported in a machined recess on the gear side of the HTOB case w/o the bolt on plastic cup.
Here is a poor angle pic of a FWD getrag with the clutch release cross shaft:


Here is the HTOB bellhousing and it is quite obbious in this pic where the shaft is supported via the case and how that location does not exist on the bellhousings with the cross shaft for the throw out bearing.

Ok ,now I understand and I know what your talking about. Having no experience with that particular model of 282, I stuck my foot in my mouth and gave some inaccurate advice. Thanks for the education on it. I'll keep my nose out of Tech from now on....Oh! and BTW, get back to work on that 4.3 swap, you haven't updated in a while, I'm really enjoying the build. -Jason
