After the past 30k or so miles of abuse my tranny has finally had enough. Currently have an Ati triple disc converter, trans go and alto clutches. Held up perfectly in the 550-600hp range. I guess it didn't like the 72 and spray. Few funky shifts at the track but it felt ok afterwards. A week later and it started slipping the 1-2 shift. Today on the way home it flared every shift even on the smallest tune and ended up stuck in 3rd. Going to drain it and check the filter but I'm assuming it is time to see George.
