better yet go with the tranny me and virgil run. You shouldnt be surprised the maggie grenaded your tranny. pm me for info on a HPM built 4L70e
I am running the same tranny as Virgil built by the same person. I have had VERY bad luck with it. It broke 2 times in 2 months with less than 2000 total miles. They wouldnt offer to help in anyway. Go FLT and do it right so you have no worries
