Im looking for a torque converter for my th350, and i purchased one for my fathers car from ******* performance, on e-bay. and it seems very sloppy as if below 3k rpm its not locking into gear, it sounds like you are taking off with a manual transmission and slipping the clutch. im trying to avoid this and i want something that i can take off like i have a stock converter for normal driving and stall out at about 3200-3500 with my 406. anyone have any opinion on a brand of converter?
