I am gathering info on a C6 to AOD swap on a 351c in a mustang. The motor has 475hp/500ft#, rearend with 3.70 gears. I have, well had a c6 that was recently rebuilt and only lasted about 20 miles. The little bit I was able to run it I realized I need another gear. A few questions:
1. Would an AOD that was rebuilt be able to handle the motor (ex. B&M)
2. Is the shift pattern 1-2-D-OD-N-R-P or 1-D-OD-N-R-P.
3. Would I need another flywheel and starter
4. Would the C6 mount and crossmember work for the AOD
5. Are the lengths close to the same
6. Will the yolk and driveshaft work from the C6
I guess what I am asking is the C6 the better tranny, if not how much extra modifications would it take to bolt the AOD into place and would it perform like a C6 but with another gear.
Thanks in advance for any help!
Well, You could build an AOD to hold that power - but you won't get 4th gear. 4th is WEAK and should never be used as a solid gear for motivation with exception of hiway over 45mph and crusing. The OD band is just not tough enough. There are some folks trying to make AOD/E/4R's to have a super strong 4th but it requires some mods like better bands and HUGE holding servo area. BUT IMHO I would not move to an AOD because you need another gear. YOu need to change the rear out if that is the case.
As for the swap info, I have never gone from c6 to aod so I can't help y ou rigth now with that. As for size - c6 is MONSTER compared to aod and the mounts are different and the flywheel. You will also have to use a TB or carb setup to run the TV cable on the AOD (no vaccum)
I will add my .02 here and say if you want a reliable/strong tranny and still want an OD I would consider the 4R70W with the Baumann TCS stand alone electronic controler. The FACTORY 4.2 V6 4R70W is rated at 400hp, with a few mods it will hold 1000 if you want it too. Check out:
