Whats better C4 C6 or AOD

looking in to trans looking for the best for acceleration but maintain highway drving

If you want to do any amount of highway, keep the AOD. That overdrive gear is a real life saver, allowing you to run plenty of axle ratio and still have it run slow on the highway. You don't get that with a C4 or C6.

keep the AOD but get better internals on it. make it into a heavy duty AOD. that way it can be used both ways, for fun, and cruisin down the road.

keep the aod.....c4's were crap, and only 3 speeds....i have broken many lol......c6's are heavy and only have 3 speeds actually the aod is an overdrive version of the old ford fmx

Keep the AOD, and convert it to a wideratio.

Where would I get these heavy duty AOD parts from?

I totally agree with that...it will make the car a whole lot faster.
If I didn't have my trans rebuilt when I bought my car 2 1/2 years ago, I would do the Wide Ratio gears right now.

Stock C4s are crap vs an AOD, however you are comparing 40 year old technology to 25 year old technology. But a C4 with its simpler design can be built to handle more power for less money and at less weight. Just like a Powerglide is a horrible choice for a street car transmission, but for all out racing, you cant beat it.

For a street car an AOD is the best choice. A C4 does not have a lock up function in 3rd gear so it kills your gas mileage, that coupled with no OD, really kills fuel efficiency

AOD!!!

C4's are tough. I couldn't kill mine. Had it behind 5 different motors and it had well over 200K. Neutral drops, 55mph WOT into reverse all the time. The only C4 I had that was a POS was the one from performance automatic.

For what you want to do ,a wide ratio AOD is the way to go.

C4+mods for a track car
c6 for trucks, especially stuff that doesn't see highway speeds normally.
AOD for a daily driver.

If you really want to get fancy and money is not a factor, use a 4R70w with a Baumanator stand alone shift controller. You'd need one from a 3.8 or 4.2L vehicle, or from a 5.0 Exploder. You get the wide ratio, all the upgrades that people move into the AOD, and complete adjustability of the shift points via the controller. Its a really slick setup, but its not cheap.
