Car Forum / GMC Cars / June 2006Muncie 4 Speed
I found this Muncie 4 speed on Ebay and I was wonndering if it would be a good buy for my 66 Chevy Pickup http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=8069787122&rd=1&ss pagename=STRK%3AMESE%3AIT&rd=1 > I found this Muncie 4 speed on Ebay and I was wonndering if it would be a > good buy for my 66 Chevy Pickup http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=8069787122&rd=1&ss pagename=STRK%3AMESE%3AIT&rd=1 what's in it now? What's the truck's intended use going to be? Is it a good tranny, the Muncie M20 was knick named the rock crusher for good reason, but your buying site unseen, and shipping is going to be fun, these things had cast iron cases and weigh a ton.

The "rock crusher" was a M-22, aluminum case, with a fine spline shaft also straight cut gears iirc. But it was a long time ago.

Wanna bet on those straight cut gears? Al's most diffinetly correct, they were not straight cut, but did have about half the angle the M20 and M21 had. The M22 was designed for road racing, not drag racing. The 21 and 22 were close ratio trannies, as such you need low gears in the rear if you want to get off the line with it. The lower angle was to reduce friction and heat, and less thrust on inner components. Myself, personally, I will take a Saginaw Super T-10 over a Muncie any day. If this truck is going to be a daily driver I want drive a truck not a car kinda thing, I would look at 92 or newer T-5 trannies for the over drive, the reason I asked what's the truck going to be used for. My first V-8 Vega was scratch built in Germany in 77, she would wheel hop one litre beer bottles, and the Muncies grenaded, twice(along with more than a few sets of spider gears). The Saginaws held up. when I got to the states with her, I got a set of Lakewood traction bars and solved the wheel hop problem. Whitelightning > > > I believe you have the wrong transmission.

The only car 4 speed with straight cut gears that I ever saw were Ford top loaders with after market gear sets. http://www.gearboxanddifferentials.com.au/ford.html Years ago Doug Nash sold them. Of course that does not mean some other transmissions don't have them, but I've seen a heck of a lot of transmissions. The M22 was used in many drag race cars. I had a few of them. The weak spot was the output shaft. They used the TH-400 yoke but they broke right at the speedometer gear, where the snap ring groove was. I broke one going in to high gear:) BTW: the five speed T5 manuals are great for a truck. Most have a fairly low first gear, and they have overdrive.

Alas because of health considerations the new Vega in process in the garage will get an automatic, upside will be a lot easier on the rest of the drive train I think(or perhaps hope) If we were just going to take her to the drags, probably a slush box, but as I want a cruiser most likely a 700R4. There is a Saginaw under the work bench though...... Whitelightning > > > Myself, personally, I will take a Saginaw Super T-10 over a Muncie any > > day. [quoted text clipped - 13 lines] > > Whitelightning Seems funny, years ago all the race cars were stick shift. Now they're all automatics. And the lowlife PowerGlide is about as good as they get.

I'd rather row my own, personally... -- lab~rat >:-) Do you want polite or do you want sincere? Seen the posting about powerglides, had to put this in, used to have a older, but much loved Chevy Nova, 4 dr, 283 with the 2 speed powerglide, that was the best car, that car would run. > > > > Myself, personally, I will take a Saginaw Super T-10 over a Muncie any > > > day.
