Who tuned it? Don't blow it up! Stock rod bolts don't like that kinda RPM that is for sure. Sounds like the tuner was possibly....

Well I'm guessing low fluid level is to blame.. i add 1 1/2 qts and it shifts at 6100-6200

If the rev limiter is 6500 your car would have bounced off it rather your fluid was low or not. Factory tach can be off by 200-300rpm also..

^^^^ That can happen at 6k or 7k. Auto car doesn't like being bounced off the limiter.
