fwiw, i have an rci on mine- fits fine. no overheating issues either. i think that's not even an issue as my heap is a street/strip 10 second monster that gets driven an hour to the track in 100+ degree heat, hot lapped, driven home, and my trans fluid temp has never gone over 200. ever. even when it was 114 last summer. i almost died on the way home. really. what matters is my car was fine. that's all that matters.
