Strange mix of parts. The side cover and tail casting are from a 1965 Muncie. The case casting date is Aug. 29, 1968.
The "13" is (1)Chevy,"3" (not 8) Chevelle, "B" Baltimore, MD assembly plant, 114807 is the VIN, and 3925660 was used for all Muncie 4 speeds. As they say, parts is parts.
Thanks to Covin's Chevrolet by the Numbers.

Mark, sounds like you have a can of worms there. Main case assembled 1968 model year put in a Chevelle, with a 1963 1/2-1965 707 side cover with a 429 tail housing 1964-mid 65 Chevys and also Pontiac A-body's thru the 1970 model year.
But all these parts will work together, as long as the gears and sycro are in good shape.
The number of rings on the input can usually tell the gear ratio...Hope this helps...Crash

Andy, 660 main case was used 1968-69 and the first half of the 1970 model year. Not all...Crash

I would agree with the partial Vin being "18", "1" for Chevrolet and "8" for 1968 model year.

[ANDY M]

OK. I can see your point. The VIN on the car itself would be 13xxx8Bxxxxxx. As we all noticed, this tranny was not put together at the factory like this.

NOT TO BE A KNOW IT ALL BUT HERE IS HOW THE TRANS. BREAKS DOWN. P8M29-p- PONTIAC(GTO)8- 1968 M-AUG. 29-DAY THE LAST LETTER IS A,B,C, A=M20 B=M21 C=M22 YOU DID NOT POST THE LAST LETTER HOPE THIS HELPS!!! THE CASE # AND TAIL CASTING # DID COME TOGATHER BUT THE SIDE IS INCORRECT IT CAME OUT OF A 1969 GTO.

Hello Tony and welcome to the site but quit yelling (cap locks). http://www.yenko.net/ubbthreads/images/graemlins/beers.gif

Hi Rick , Sorry about the capital letters . Northfield , 20 minutes south of Burnsville. GO VIKES !! Yes, I'm Yelling that. Tony

[crash]

The A B C ratio indicator didn't start to be used until the 1969 model year (Oct 21 1968)... Crash

[crash]

The 707 sidecover was used 1963 1/2 thru 1965 model years... 1969 model year used 306 sidecover...Crash

Also, "P" doesn't indicate Pontiac. It indicates a Muncie 4 speed transmission for passenger cars (except the Corvair).

Sorry abut the misinformation on the A B C codes, my over sight. Indeed they were not used until 1969. Use the input shaft for ID 2 groves =M20 1 grove = M21 no grove = M22. Just try to help out . Tony

[just love cars]

The P works up to 1967 early 68. Then they changed that to HI (CHEVY) code if it was a special order such as a 396SS they put the P in the third digit "HIP". The case and tail numbers where put together by Pontiac. I have one in my garage. I know it came out of a GTO. Tony

[bertfam]

Tony,

I'm not sure where you got your information from, but I don't think it's correct. I've never heard of this and there's nothing in any of my reference material mentioning the "HI" or the "HIP" codes. "Chevy By the Numbers" has no info on these as well.

The "P" was used on the Muncie 4 speed (aluminum case) starting in the late 1963 model year (for Corvettes), up through the 1974 model year.

Although there are a lot of good WEB sites with Muncie info in them, HERE'S ONE (http://www.angelfire.com/space/slr/trannyid.html) I found doing a quick Google search. Others might chime in with more.

You should also pick up a copy of Alan Colvin's books, "Chevy By the Numbers" series. They have a TON of great info in them, and Alan's even a member of the Camaro Research Group (http://www.camaros.org/index.shtml).

I got that from a chevelle ss restoratioin guide. Just shows you can't believe every thing you read. Tony

If Paul Herd wrote it,Throw it away. http://www.mcrel.org/whelmers/images/trash.gif

[just love cars]

Yep, he wrote it. This is why this site is so cool. I would have been trying to find a trans. with that code. I got engough of that right now. I rescued a 1968 Chevelle 396SS from a field. Tony http://www.yenko.net/ubbthreads/images/graemlins/3gears.gif

Tony, What color and horse power is your '68 SS Chevelle?

[just love cars]

Right now it is all colors, But it looks to me to be some teal blue color with a black stripe. I just got the car a month ago and really just have not gotten that far with it yet. I has no motor, but the 4 speed M21 ( no shifter) and 12 bolt posi are there and both are good. Interior black. Has the gauges & tach instead of the idiot lights. The car came from Texas the frame is solid. It sat in the back woods/field since 1988 I found unused plates in the trunk and the plate # match the tile. But it was a mouse condo. I evicted 10 adults and a couple of nests. Interior all gone. I mean everything. But they left the wiring alone. Tony
