Hey guys and gals. Just thought id ask some personal experiences between two performance transmission companies. I've heard good and bad from both. I can rebuild my transmission on my own. But id rather send it our since my final goals for the car are 500 hp. Anyway. What are your views on dogboxracing or shep transmissions? I know john sheppard is in the 7s but that is his trans. Both services are about the same cost so its a coin flip. I would like people to chime in whom have personal experiences with either company. I don't want to hear your friends cousin has one. I want prsonal opinions please. Thanks
