I'm 60 and have been shifting an 833 since I was 16 years old. My Cuda that I've have for 40 years has the close ratio 70.5 up. It just needs one more gear in today's world. I installed a Tremec from Kesler in a buds 528 Hemi. It shifts like a truck, not like an 833. It has broken on him twice. He sent it off to some special place and it helped in shifting, but not much. It just won't handle his 650 horse Hemi. I'm putting in a Passom Hemi OD 4 speed today for a guy. I think it's the best compromise right now. It should handle the torque AND shift. I don't know if Jammie will ever get up to speed producing the new 5 speed or not. My bud may sell his Tremec if we like the way this 4 speed OD works.
