ok so what if its laying in a yard, not hooked to anything and where you dont have the ability to "rap the **** out of it and dump it into gear"....then how do you tell?
On the C6 the bell and the main body is one piece. The C4 and the FMX have a bells that will unbolt. The C4 Has an aluminum main body were the FMX has a cast iron main body. There are some C3 out there, You want to stay away from them if your using a V8.
Done, nuff said. For that matter, you can tell a C4 from anything. A C6 is a monster as compared to an AOD and an FMX is slightly smaller as well. Depends what you're looking at, it will narrow your options.
There are also C5s which look similar to a C4 but are a little stronger. They were used in some things later on, couldn't tell you in what though. I had one in a stout Cleveland powered '69 Mustang once but the drivetrain was not original.
from underneath, c-4 has a small, square pan...and removable bellhousing, as mentioned above. I think the pan looks similar on an fmx, if I remember right, but these have a cast iron housing, don't they? ( the fmx...?) the c-6 pan looks more like a chebby trans pan, with an indented area...not square.
C5's were 82-86 and had the lock-up converter. Also some C4's have a pan fill and other have a case fill I think 1970 is when they changed.
Bolt both to a "built" big block.....the one that goes up in smoke is the C4 -Lee www.atomicpinup.com
lots of folks running 'em behind big blocks, nowadays...less parasitic loss. A hardened input shaft, and a good build, and it will take it. not out of the box, maybe...but, a good trans., easily built to handle power.
"lots of folks running 'em behind big blocks, nowadays...less parasitic loss. A hardened input shaft, and a good build, and it will take it. not out of the box, maybe...but, a good trans., easily built to handle power" Actually, I agree and if they're built, C4's hold-up pretty good. The same can be said for TH350s on the Chevy side. -Lee www.atomicpinup.com
There are more than a couple Ford trannies w/ detachable bells, case in point the FMX is visually close, but dimensionally different.
It just really depends what he's lookin/around. Once you get into the later years, FMX, AOD, AODE, and all that ****, there are more with detachable bells. I was thinking he was looking more towards 60's early 70's. In which case the C4 weas the only one w/ a detachable bell no?
no..... Ford used the FMX trans into the early - mid 1970's. Bell housing bolted on... center section of main case would be cast iron though.
Nah, a bunch of ****. FMX, C4, Cruiseomatic, I think Fordomatic was an integral bell. Lemme think what else...Hydramatic (a tad earlier) behind the Linc Y blocks...prolly some other stuff. FMX was 70s tho. AOD line is one piece case tho, E etc as far as I know.
