hello everyone.
what i have is a '76 F-150 extended cab truck. under the hood you find a 360 mated to a C-6. i have aquired a 302/AOD, that came out of a '75 regular cab. i need to know if i need to get the steel chassis mounts for a small block, or are they the same. also do i need to buy another tranny crossover, or will the current one work? and do i need to custom cut a driveshaft? or does one exist and i need to go find one? the AOD is several inches shorter than the C-6. i also believe that the 360 is longer than the 302.
thank you for your time and i look forward to hearing an answer.

The engine perches differ between 302 and 360. I swapped a 300 for a 302 in a 76 F100. The frame and crossmember is already drilled for different engine perches. The 300 towers were roughly parellel with the crossmember or perpendicular to the frame. Judging from the look of the 390 in my 69 F100, The 360 perch may be the same as the 300. The 302 perches mounted back about an inch in different holes and angled back toward the cab. The interchange info from the wrecking yard identified them as being for 302,351M,400. I'm told they also work for 351W. Regarding the Tranny crossmember, I also swapped a smallblock C6 into the truck and had to have new holes drilled back a couple of inches from the two sets already in the frame (302 in 76 came w/ C4 so C6 was a custom arrangement and I don't think my C6 was originally a truck tranny). The actual (original)crossmember was simply located further back on the frame rails. I'm assuming that the 302/AOD was transplanted into the 75 truck, as I don't think that AOD existed until the mid 80's and requires EEC computer control. Is this a fuel injected 5.0? If so are you accounting for things like fuel line and pump modifications and sensors for the EEC? There was a C5 tranny from the earlier 80's that is an automatic overdrive but not dependent on the EEC computer. Is this what you have or is it really an AOD? Finding an existing driveline might be hard. I had a new driveline made for my rig and it was expensive. I would look for an extended cab with a manual transmission because I believe that they have much shorter tailshafts than a C6. Shortening a driveline is cheaper than lengthening one.

 

i have started the project and here is the updated results as of 2000 hrs. i have the 302('75) and the (i was told) AOD sitting in the truck. the 302 is sitting on the steel chassis mounts that held the 360. the tranny wants to meet up with the original crossover but is about 2 inches too far forward. i am going to search the junk yard for some different chassis mounts and then i believe that the tranny will bolt. as to the drive shaft, it looks like the shaft is also just a few inches short. after i move the power plant back, i will be able to tell more.
the tranny has no electric control box. the old guy that i got it from said it works off of centifugal force. and he said that it came out of a mid-80's vehicle. im not sure he actually said what, just that it was mid-80's.
more to come after the project is moving on its own power.
one more thing... how difficult is it to change the outer shifting shaft on the
AOD. it is bent and slipping a little when i manually actuate through the gears. i have the C-6 i can rob it off of if needs be.
thanks

Look for 302,351,400 perches they will shift your motor back. I still think you have a C5 overdrive tranny and not an AOD. A C5 is an automatic with overdrive but not computer controlled. My experience driveing Ford E vans with this tranny in the early to mid 80's (back in the 55mph era) was that they couldn't decide between drive and overdrive at 55. With higher speed limits, they probably work better.

 

i have located a set of steel chassis mounts that will move the engine back several inches and i will be putting them in tomorrow. there is definitely a difference.
about the tranny problem of the shifter, (read second message) what is recommended that i do?
see you all later.
ps. how you tell that the tranny is an AOD or a C-5. i am really curious.
thanks Mr Big Brown Truck.

I haven't looked at either tranny up close, but I have driven vehicles with both. The shift pattern for the C5 was P R OD D 2 1 the Aod was like reg auto's P R D 2 1 and the OD was either on or deactivated by a pushbutton on the end of the shiftlever. The AOD requires the EEC computer to control shifting. I'd talk to a tranny shop or search for info on the web. I've seen somewhere pictures to identify tranny's. I can't help with the lever fix, I haven't ever done anything with a tranny besides remove or install. When I changed my chassis mount from the 300 to the 302, I found that the 302 mounts matched up with different holes in the frame/crossmember area than the 300 used. They were already there about an inch back. I'd unbolt the tranny cross member but leave it resting on the framerails and see where it ends up after your engine is sitting on the perches, you may have to drill new holes, but if it all goes rearward your drive line may work or at least be long enough to shorten.

 

The aod tranny does not use any electronics to control shifting. it uses a t.v. cable. The aode uses the eec to control its shifting.

 

 

hello again
i just put in the small block chassis mounts and the whole thingshifted rearward. i had to wrestle the tranny crossover in, as it was a really close fit, but all the original holes are being utilized.
the next thing is how much input shaft needs to be inside the tranny? if its more than an inch, i am going to have to find another drive shaft or get really creative. i also need to modify my tranny cooling lines, as the routing into the tranny is physically different.i might just get new lines, or find some in the salvage yard.
one more thing.... the harness on the engine that supplies the juice to the coil and the distributor...... is there an interchangeable one off of another vehicle? the old engine was points and condensor and the wiring harness was left hanging and has gotten kind of oily. (read filthy)
thanks. thats all for now.

 

jimmytak,

A Ford C-5 (They were only available from late-'70's to mid-'80's in F-150s and E-150s) is commonly mistaken for a Ford AOD. In fact, most people call the two different transmissions an AOD.
Here's how to tell: A C-5 has P R N OD D 2 1 for a shift pattern and is not computer-controlled. A true AOD has P R N OD 2 1 for a shift pattern and overdrive is locked-out by a shift-lever or dash-mounted switch. An AOD is also EEC-controlled.
Hope this helps.
