I bought a transmission today because the price was right here is the numbers D2AP7006AA 17 can someone tell me what I have and the value thanks Eric
Thanks Dave your alright even what they say about ya(just kidding I new) its a 1972 c6 . the guy told me it was out of his buddies 1972 Mach 1 when they put 4 speed in.I was hoping for a c4
the guy I bought it from insists its a fmx trans code he gave me says not I will look numbers for myself when I get a chance anyway only 35 dollars spent and its clean no leaks,just need to swap for good c-4
The easy way to tell the difference between the C6, C4, and FMX is: C6 - all aluminum - bellhousing cast into main body of transmission C4 - all aluminum - bolt-on bellhousing FMX - cast iron case - bolt-on bellhousing
thanks Paul when I get it home i will check better,what the pan shape and size is also,at the price and cold weather,he told about it and it was clean,only glanced knowing a deal but also knowing I didnt need or really want it
Well I got transmission home its 20 degrees out,not going to do anything with it today but take pictures BBBrrr View attachment 39195 View attachment 39196 View attachment 39197 View attachment 39198 View attachment 39199
fmx looks like fmx to me will it bolt up to a 250 ,change behousing? thanks for any info.Still hasnt been warm enough to check vacuum lines on car
Yep, FMX is what it is - If that is a small block v8 bell on it then it will bolt right up to the 250 six. Getting a zero balance flex plate to fit might be a bit harder.
I'd keep the FMX, provided you can get a flexplate for it. Tougher than any C-4. But if you want to pay the freight to Louisiana, I'll swap you for a good C-4 that's ready to run.
I am still deciding I will have to get a 0 balance flexplate,the one on the c4 is differant? also the bell housing from mine wont work?if the fmx was from a big block.There is a transmission scrap shop close by,if I need these parts.oil is just starting to look brown in my c4 going to try part oil change and adjust bands when I get a chance.but its probablly to late my luck.I called the guy Ibought it from and it was from a 72 mach 1 big block engine bell housing is differant
That looks like a small bell FMX. I've got two of these plus one for an FE series big block. C-4 flexplates are different from FMX units.
It is really a matter of opinion whether the FMX is stronger than a C4 or not but I do know that the center support in the FMX is really the point of concern. That web breaks often enough in normal use that there is a "repair kit" for it. The kit consists of a special drill guide, drill, tap and a long socket head screw. With a weakness like that I put my money on the C4 every time. The only broken cases I have ever seen on C4s were from modifications to servo pistons running high apply pressures. I have never seen a C4 case break in an unmodified car. I have repaired a few of the cast iron cases myself in stock cars.
I got the c-4 transmission working good,the bands were out of adjustment and looked like they used the wrong kind of oil.so I wont need the boat anchor fmx out of the 72 mach 1, boy I am glad I know I would have spent more money having to change transmissions
