C6 vs. AOD
I currently have a C6 in a 86 F150. I am doing some upgrading to the truck for towing. I would like to replace the current 2.47 rear axle ratio with 4.10's. My question is, how is the AOD transmissions for towing? I love the C6 but would like an overdrive gear. Would the gas mileage be terrible with 4.10's and the C6? I currently get around 12-14 empty. Ithink the current ratio is just too high even with no load.
Thanks in advance.

I've been studing this issue for some time now as I have a CC Dually 85 410 rear and a 460/c6. Gas mileage can be figured in feet. Tail shaft Gear Vendors are great in quality and expence. AOD with change over cost is great also. AOD with new input shaft is trustworthy and gives the greatest overdrive %. Brownie aux. transmission is a good alternative if you can find one. All in all change over cost equals truck value many times in the older vehicles.
Good luck, let me know if you find a good answer.

I think AOD's are very good transmissions if they are kept in adjustment. I bet over 90% of the time one fails is because the TV cable wasnt adjusted properly or lack of maintence.

I'd rather have a C-6 any day of the week over an AOD. The C-6 is cheaper and easier to work on and you dont have to mess with computers and stuff.
460/C-6 is the best combination that Ford made for gasoline engines, in my opinion.

There is no computer with an AOD. I have 110k on mine and it works perfect. I use ATF+3 for Chrysler vehicles because the friction modifiers are better. I agree that they are a good trans I should have put one in my Ranger when I put the 302 in it.

I put 220K on mine towing heavy things before I lost a spring and roller clutch - so with my miles I did a full rebuild. the key for an AOD is frequent oil changes and a very large cooler.
if you have a few extra $$ laying around, there is a new gearset for 1-2 that adds about 15% ratio internally, there is a much larger band, and kevalr clutches available.
