[98SteedaGT]

I don't know if this will help or not. I have the 4R70W and I run 3.73 with 3clutch Ford Posi, not 2. I haven't had any problems with mine. The place that put the gears in my car puts them in the 96-98 GT's all the time, they haven't had any probs. They have noticed that the 3.73 seems to make the Auto4.6 real happy. I think the guys with the T45 went with 4.10 on there's. I don't know all the exact diffs between the AODE and 4R70W other than the GearSet and the Mechanical Diode, mostly just stuff I have read about. The tranny is the one thing I haven't messed with yet.
