Muncie identification

Can anyone give me a list of how to determine what type of vehicle a Muncie was installed in? I got the dates and castings numbers figured out just not the plant origin or type of car.

Thanks

Re: Muncie identification

Without a VIN number? Good luck, unless it's a real odd ball. You willing to share pictures and numbers? That might help, maybe.

The only reason someone would want insurance is if they want to pay someone elses bills or want someone else to pay their bills.

Re: Muncie identification

I have multiple ones I need to decode and would just like to know how to do it myself. Yes, they do have a VIN

Re: Muncie identification

Unless a long tail shaft, itís going to be pretty hard to figure out what type of car it came from, AFAIK. Whatís the interest for this information? What are you trying to accomplish?

IMHO, The easiest way to figure what car a Muncie could have come from would be the rare 1970 LS6 M-22 which came A year early in 26 spline when all other muncies up to the 1970 year were still 10 spline inputs, and still then it could have been in either a corvette or a chevelle. 71-74 muncies were all 26 spline inputs.

Looks to be a 1968 trans from the one pic. Whatís the main case number and number of rings or grooves on the input shaft?

Re: Muncie identification

In the right picture the 3rd digit (VIN) is an 'N" and I think that is for Norwood, Ohio. That plant built Camaros. I think that is how its done but don't have a full list of the plants and exactly what digit is for the plant.

In the Wiki chart where it says VIN, that would decode to the letter (or number) stamped on the transmission as the plant that installed that transmission. Your picture that starts with 18N, 1 means Chevrolet, 8 means 1968, N is for Norwood. Norwood made Camaros. Second picture has a 29O, the 2 means Pontiac, 9 is 1969, not sure what plant used the letter O. GM manufacturing brands were coded by numbers, but I'm too lazy to go digging in my basement right now to find what all the different codes are. Buick, Oldsmobile and Cadillac each had their own number, just as Chevy and Pontiac did.

That would be 100% correct..... N is the Norwood plant that built Camaros. This transmission is from a '68 Camaro. VIN would have been 124378N314135 or 124678N314135 if it was a convertible.

Re: Muncie identification

If you would, please post the information here: 1968 - Orphans You never know...... someone may be looking for their original transmission. That transmission is worth the most to the owner of it's original car.
