CP is correct.
Friend of mine from Prince George BC put the (is it TKO600) into a bone stock 440R/T 4spd and he ripped one of the gears (cannot remember which) out 3 times - yes! 3 times. So he sent the tranny back and put the A833 back in. So you guys must be driving these things like Grandma does if they are staying together. That is why I have an A833OD in mine.
