automatic transmission and a dodge cummins

transamz9 is exactly right. If you add goodies to the engine to add power you better beef the trans. My engine is staying stock. Trans is getting close to needing some attention as there is no adjustment left in the front band. When I do it there will be an upgraded converter put in. Not for power but for longevity. These things make more than enough power to get you in plenty of trouble when they are stock. A friend has an 07 or 08 and has the 6 speed and factory EB which would be nice.
