Ok, i have around 180K miles on my 700r4 tranny and i think that its gonna need to be replaced pretty soon. Also here and there i do some racing and i dont like the 700r4 that much because the gears kick down to much whenever i start in Overdrive or sometimes it wont shift from 2 to 3rd when im manually shifting. Anyways i just wanted to know if i replace my tranny which one out there is the best one to use and without doing that many modifications? I do daily driving and on weekends is my fun time. I want something that will get me off the line fast, shift quick, and all that good stuff. Anyways i was just curious which one i should use if i change my tranny. Thanks
