I think I’d want to know what failed, hate to upgrade the trans, but not know if you’re upgrading the failure point.
If you’re breaking hard parts, going down in HP rating to the more expensive heavy hauler max might be more durable in your application than the black edition. Softer shift might be ******* clutches, but if that’s not where you’re having trouble, softer shift might of saved the part that broke, and be easier on the rest of your driveline. If the black edition holds, it might test the next weakest link in your driveline
