Has anyone ever done a C3 to C6 transmission swap? I found a re-man 302 police interceptor with a C6 that I want to use to replace the 200 I-6/ C3 set up currently in my 50' Ford. Yeah I know, for the most part around here 'If you don't know we're not going to tell you' but any help would be greatly appreciated.
I would think that the trans would be a C-4. As far as I know the C-3 was only used behind V-6 engines in pintos, and behind 2.3 engines in the same
With a torch and welder Know how and a whole lotta wont too. Its very simple? sounds like a good ides too me.Old wolf
The C3 was introduced as a lightweight 3-speed automatic for compact cars like the Ford Pinto. It was used with four cylinder, small V6, and the 200ci Inline Six engines. The final appearance of this transmission was in the 1989 Merkur XR4Ti. I don't believe that they can be swapped without some adapter work, as the bolt pattern radius of the C3 bellhousing, and the motors it was used with, is much smaller than the C6. One possibility is, instead of using a C6, would be to use a C4. Both the C3 and C4 have bolt on bellhousings, so if that pattern is the same, you may be able to bolt a C4 in place of the C3, keeping the C3 bellhousing. Never done it, don't know if it would work, but it'd be a lot more feasible than a C6 swap. Plus a C6 is a power hog, and takes a lot more HP to turn it's guts than a C4 takes. With a 200ci six, you don't have a lot of horsepower to spare. I'm not sure what Old Wolf is trying to say, he might not be fully awake yet.
Orlando, Are you swapping the whole 302 engine/trans package in? You have to be more specific to get good answers.
Sounds like he's swapping out the 6 & C3 for the 302/C6. He'll probably have to make some changes to the ****** mount & the driveshaft to get the C6 in. As was mentioned, unless the 302 is really stout, like built for racing, the C6 is way more ****** than needed. C4 would be better for the typical 302. C6 was for the 4 bl 351 Cs & up.
They did put a C3 behind the '80-'82 200 with the low mount starter as far as I have been told. That block uses a bell pattern that is like 2/3s of the regular small block pattern. If that is the case, he'll need to drill a couple of mounting holes transfered off of the new bell from the C6 into the back of the engine block. Then the c6 should bolt up. You're on your own as far as flex plate and such, but my bet would be on the 300 six for that. Both are zero balanced, and should be compatible with the larger ring gear.
Yeah, now that I read it again, it seems that the thread ***le doesn't quite match the post. Sounds like a complete engine/trans swap.
Sounds like a good swap. Dont know if the C6 will fit because of the large size. If I remember correctly the C3/C4 belling housing wont swap because the one on the C3 is part of the front pump.
I stand corrected on that one. It was used behind a 200 6 cyl. The major problen with any modifications, is that the beelhousinf is also the front of the pump ***embly. This trans was also the basis for the A4LD overdrive trans used in ranger pisckups, broncoII and explorers. This transmission made me a lot of money when I was a mechanic in a Ford Dealership. This is a really light duty transmission
When on Earth did Ford ever use a C6 behind a 302? There were smallblock C6s but I've never seen one behind anything but a 351C/351M/small-pattern 400M.
they used them in lots of 300 powered pickups in the 80s....and that trans will bolt up to a 302. I wonder how much power you have to be running thru a C6 to make it eat up 65 hp? I hear the same claims about a TH400 using gobs of horsepower...yet my car will move with the engine idling, and I know it ain't making 65 hp then...
I ***umed he was wanting to swap a 302engine and c6 trans into his car. engine& trans conversons are almost never a bolt in. But with a torch & welder anything is possible. With a torch & welder and know how + want too you can install a nail head into a 60 falcon!
Oh, I know it WILL bolt up, but my question was what Ford vehicle combination ever came that way from the factory? Of all the slushboxes one could choose to bolt up to a 302 it seems to me you'd have to have a very good reason to want to use a C6.
I don't know, I quit working at the junkyard in 1982....but this might tell you something? http://www.rockauto.com/catalog/x,carcode,1121443,parttype,8600
Okay, understood. At least now if for some reason I ever wanted a smallblock C6 I know what to look for...
Yup whole thing is going in. That six cyclender has pissed me off for the last time. Yeah, that's how it came and it was free. I'm told this set up came out of a old cop car in some hick town in Florida. Looking at the reman numbers and how everything else is set up along with the HD C6 tran that seems to be the story. the 200/C3 set up is what was in the car when I got it and I only paid $1000 for the whole deal, and I knew there were problems with the Trans when I bought the thing. Yeah, its junk.
