I just put on a supercharger and when I'm at WOT I'm pretty sure the auto trans is slipping when it shifts from either 2-3 or 3-4. It won't do this when I'm running the B&M shift plus on stage 2.
Is this normal or what could it be? The trans only has 76,000 miles.
Thanks.
change the ATF. B&M trickshift works wonders. if that doesnt fix it then i dont know
