just wanted to know if there is any recommendations on a time period before punishing a fresh rebuilt tranny? Also should there be an initial oil change prior to the first scheduled 15,000 mi. one? I know engines are different and I've built probably a dozen or so and most people tell you to baby them during break-in but I have always broke them in the way I plan to drive them short of winding them up to the red line repetively 'til I got 500 mi. on them and have never had a prob. and I do a first oil change after the first 1/2 hour of running and then after the first 500 mi. but I know a trans is not reciprocating, metal to metal eng. and just curious on the break-in thoughts on a tranny.
