OK I have a 94 full size blazer, and my trans is on its way out the door. I believe that i have a 4l60e in it currently and was looking to swap it with the 4l65e. Ive been searching around and keep getting mixed reviews. How much stronger is the 4l65e and will it be a clean swap?? Im not looking to have it be real involved. any advice would be much appreciated.
