I found a reasonable priced C6 for sale(disassembled), and need some help with identification. The guy selling it says that he was told that it came off of a 351 Cleveland by the person who sold it to him. I just want to verify this to make sure that the bell housing will mate to my 351C, before I drop some cash on this tranny.

Casting numbers are:
D7UP-7006-AA : This is located just above the pan on the drivers side

24 : this is really big, and located on the top of the bellhousing

Next there is a part with numerous part numbers. I do not know what to call this part so please bear with me. It is a cylinder about 4 inches in diameter with one concave side, sticking out of the middle of the concave side is a shaft about 5 inches(?) long. On the opposite side there are several castings : N, RF-D3AP, D3AP, and 7D027-AA .

And finally on the tail shaft: D1AP7A040 AA, and a big 11

Thanks, Cody

I'm going to guess that it is a 77 trans, but I'm not a casting # guru so someone else step in and verify. If it is a 77 it would have to come off a 351 windsor to fit your C since C's were not built as late as 77. If the guy said it came off a Cleavland I'm afraid he might be confusing it with the 351/400 modified, as alot of people do.

If it came off a 351/400 it will NOT fit your Cleavland. Smallblock C6's are a little hard to come buy. Most in the later 70's would be found in trucks and vans with 351w's. mm

U is Van

D7U is 77 Van thanks MM and no van was issued with a Cleveland engine in any years as far as I know. If you want a real C6 case I of course have one off a real 351C 72 Cougar. What the fellow is offering from where I stand may be a 351 M trans housing which fits I think 351M 400 429 and 460 That's it. Many get confused by the "look" of an "M" engine which uses the C heads and W crank however lots of vans were issued w/Windsor engines so you may get lucky. Take into account that the van is a column shift and the car is a console shift so w/o the correct lever you will not be shiftin gears. Note that C6 rebuild kits are only $100 and overhauling a trans in either C4 or C6 form is relatively easy. Knowing nothing about tailshaft lengths I advize you to take a look at it as well. Take a few measurements or see how the starter bolts or look at some pix or run the # at your local Ford dealership.Best'O Catzyalater

Could I just compare the bellhousing bolt pattern on the C6 to the bell housing of the transmission that originally came off the Cleveland?

 

[Ray]

Yes go and compare bolting patterns/flanges etc thats a good idea. Also might wanna check overall lengths. Don't forget the shift levers are diff at 180 out tween catz and vans. Catzyalater

Now that I know for sure that I will need a different shift lever, what kind would you suggest? I had planned on getting a Hurst Quarter Stick, will it work?

Ray and ModifiedMark, thanks for all the help.

Its the shift lever on the trans not the shifter itself that is 180 out from console shift to column shift. I myself can only recommend the original shifter. It shifts as fast as any aftermarket shifter in my opinion and does not cost a fortune. The only prob w/original shifters is after 30 years the bushings wear out a $10 repair.Ray
