Well my 4l60 decided that it liked first gear so much that it will no longer leave it. I am having it rebuilt by a local guy who has done some others before for me and my dad, but anyway. I originally want a 2800-3000 stall but sence i am at school my dad took the truck in the guy talked him out of the 3000 and is going to put in a 2200 not sure on the brand. But do you think I will notice a difference over the stock converter?
