Hello, I have a 1998 chevy 1500 truck. It's got the 5.7 V8 with 4WD. When I floor it or even get close to flooring it, it seems like the tranny wants to slip. When I floor it all the way, the motor revvs up but the truck doesn't go at all. My dad thinks the problem is an electrical problem. I was just wondering what yall think the problem is..

Thanks,
Nathan
