what is a good torque convertor

if you are happy with that converter then just get it rebalanced any one of these great company's mentioned here will do that for you .

I will do that Bruce. Jimjim, I am afraid that the reason it may be unbalanced could be something inside and adding a weight may not fix the problem. I am going to call around tomorrow and check prices. The tranny shop told me today they would put one in if I got it for them as I am not ready to tackle that job again, not yet.
