Have a wierd issue since new drivetrain. I can be moving along at a good speed and roll up to high speeds no problem. But let say I'm doing 55-60 and I mash it. It sling shots to 85 and suddenly drops out of O/D. Won't go back unless I go to nuetral first. No trouble codes. At first I thought it was fuel starvation because it was always at high rpm's. Installed an ADII and didn't really see a change.
