torque converter

i am about to rebuild a AOD to replace the C6 in my truck and i am going to use TCI Auto 438905 - TCI Pro Super Transmission Overhaul Kits. so when i get it built i was wanting to get a better torque converter. i am running a stock 302 for now but i am going to build a 347 stroker for it some time next year. i dont know what stall converter to get. it is a daily driver but i like to race with it every now and then so a stock converter isnt rally the best. any suggestions on what stall to get. oh yea i dont tow with this truck either

If your going to build a AOD for a 347 stroker i would look into using the wide ratio gear sets from a 4R70W , there better & stronger . Shift kit is good & trans cooler also . I wouldn't get a hi stall converter untill you build the motor & pick your cam & intake, Depending on where your motor starts to make good HP will tell you what stall you need ....JMO .....Lew

TCI can advise you and sell you one, methinks. Locking or non-locking. Ditto 4R70W parts, that's the way they beef the AOD.

Good luck.

ok i have found some info about the 4R70W and it is better but it is electronically controlled to what would i have to do to make it work? and that site with the info on it said its best to be used with a locking converter.

If I'm understanding the beef-up story, they use AOD-E and 4R70W parts in the AOD case--cases are similar, pans are the same. You can sort through the propaganda at TCI and other sites to see what they change in the transmissions they sell. Input shafts, drums, stuff like that there:

TCI - Ford AOD, AODE and 4R70W

AOD Performance Products - Baumann Electronic Controls

AOD Transmission from PATC, AOD Transmissions

www.CKPerformance.com

As for a torque converters...a lock up converter locks up like a manual trans clutch under cruise situations. I'm not sure if a higher stall converter can be lock up. If you go with a non-lock up converter, and your stall is higher than your cruise rpm, that could be trouble.

A high stall converter is going to build more heat also, so a cooler is probably in order.

Gears etc make a difference in what stall is better. Depending on what you do to the 347, a good stall for it might not be a good one for the 302.

I'd wait on the TC until I did the 347.
