torqu converters
i have an 89 ford bronco302. After i get a new AOD transmission i want to get a new torque converter, but i don't know anything about the stall rating or anything. I found one in jegs magazine but it seas it has 2000 rpm stall rating and i dont know what that is. So if you can please help.

if you want torque at lower rpms, then get a converter that stalls at the lowest rpm possible. If you want torque at higher rpms, get one that stalls at a higher rpm. Usually for a non racing truck it's best to have it at a lower rpm especially if you tow occasionally.If you are just looking to make it better off the line go with a higher rpm.
Hope I helped you in anyway.

Also its good to match the converter stall speed to your engines power band. Example being you built your engine for 1500-6500 RPM power, a 2000 RPM converter would be ideal, while a stock converter would somewhat smother the engine off the line since it wouldn't let it rev up into its powerband before beginning to really engage. Another note is the higher the stall speed on the converter the more it slips, this means lower fuel economy and alot more heat produced by the tranny, if you go with a higher stall converter a very large tranny cooler is a very good idea especially in the AOD or you may cook the tranny. The AOD also employs a type of "lock up" converter stock, and the 2000 RPM converter you are refferencing may not have that function, which will cause the converter to slip quite a bit more in 4th generating plenty of heat and less fuel economy. Though the TCI streetfighter converters do have a lock up function. I do hope this helps some more even if it was a bit long winded
