What are the symptoms of a bad torque converter?


Well I'm going to have to do that then! Because I was expecting more from this motor.

Would 4.10s be too much, because I think I can find a good 3rd member. I already have two, a 2.92, 3.23, but those ratios aren't high enough. Or can you swap the crown and pinion from one of those gears with some better gears?
