Help me pick a tranny...
Just picked up a 460 out of a 78 pickup. I am planning on putting it in my 66 f100 shortbed. What transmission would you all swap in behind it? I would like to have overdrive... I was thinking an aod or t-5 out of a passenger car would be good if it would mate up... I dont care auto or manual. Let me know what you guys think. Thanks in advance.

To be honest, I know cars better than the trucks and I didnt know what transmissions came in most trucks. That sounds like a good idea. Are any of those better or worse? Do those require some sort of electronic device to shift?

AOD's are good but the adapter plates can run in the $750-800 range. The Adapter kits come with a new starter, flexplate, crank hub adapter, and hardware as well. If you looking to build the 460 later your going to have to rebuild the AOD to handle the extra HP and TQ. 400 HP is about the safest limit a stock AOD can handle. E4OD's are the ones that require a brain box to control them. An AOD needs to have a cable attached to tell the tranny where the throttle is. If that is not set up correctly the thing will eat itself alive. There is also the option of using a C6 with a gear vendors overdrive unit. The over drive unit can handle anything you throw at it according to the website propaganda. If you want a manual a T-5 can be bolted on with an adapter or go the ZF-5 route which was made to bolt on the 460.

What size tire and gear do you run in your truck airharley? I just want to be able to take the truck on a cruise if I want and would also like to get out of the hole if it makes it to the track as well. This is why I was hoping for overdrive, but the automatic ideas are not sounding very affordable.

I am running a set of 275/65R15's with 3:89's through a C6. My highway speeds are limited by how fast the engine is screaming at 70 though, 3000 rpm. I am looking to swap the rearend gears to a set of 2:80's in the next few months or so. My engine has plenty of grunt to push that gear ratio off the line and still get descent gas milage. I am also saving for a wide ratio gear and 500 hp rebuild kit for the C6 as well which will give me back the off the line acceleration that I have now. The tranny kits will cost about $600 total so that in my mind offsets shelling out $2000 for the AOD and adapter kit.

C-6 transmission..period. The AOD was the worst transmission Ford ever made. The C-6 was the best transmission Ford ever made.
AOD's are expensive to repair, and expensive to adapt. Even when repaired properly, the transmission is still prone to failure. Heat is the enemy. The money spent on an AOD will buy a heck of a lotta gas.

A gear change and the c6 sounds a lot more appealing than all of the work required for an aod. What engine modifications have you done airharley?
Thanks for all of the input guys. I really appreciate it.

The C6 is a better tranny, but I believe the AOD can be built to handle more stress, and there are a lot of factory installs still behind 460 truck engines today. They have the parts available to make the AOD much better than factory. These folks build them to drag race with http://www.becontrols.com/ There are other companies out there as well. IMHO

If you look in my gallery you can see the list of parts that have been changed out. Basically the only stock parts left are the head castings, block, water pump, and crank shaft. Everything else is brand new or aftermarket. The valves were upgraded to 2.19/1.76 to improve on the flow a bit and the smogs bumps were ground flush to the floor. I did a little bit of gasket matching as well. I invested roughly $5000 in parts and machine work. I did a lot of part searching through the internet to find items that were cheaper. Otherwise I would have spent a lot more then what I did.

Clark 4 speed? With the 2 foot shifter throws? Are you talking about the Ford 4 speed OD as pictured here?
http://www.motivegear.com/tech_info/...nny_guide.html
Getting back to the question at hand. The AOD, as advertised here:
http://www.transmissioncenter.net/AOD.htm
http://www.becontrols.com/products/aodcat.htm
http://ckperformance.com/ford_aod.html
http://www.tciauto.com/Products/Ford/ford_aod.asp
can certainly do the job, even with wide ratios and an OD.
But you already have a good trans in the C6. You spent $5000 on motor work, so is it unreasonable to spend $2 or 3,000 on a trans or OD?
I'd go Gear Vendors, just because it would go in without fooling with the rest of the truck as much as the OD trans option, plus you will have 6 gears instead of 4.

As for manual trans options, the T-5 won't take the torque you have for long, and a ZF is not a fast shifter, and has the low first, and od, so the gear spreads aren't really "performance". The Ford OD 4 speed is poorly geared and weak in OD as well. Other 5/6 speeds will start making the Gear Vendors deal look cheap.

Thanks guys appreciate all of the info. Where you guys go to get a converter for a c6? I have gotten c4 converters from performance automatic and was not very happy, and got another from continental and am very pleased with results so far, but this is in a mustang, not something that could potentially be used as a tow vehicle...
As for the zf what year trucks do I need to look for. Is the bolt pattern the same between the 460 and the 7.3 diesel in terms of the bellhousing?
