99 Silverado 5.3 will buck or kinda jerk if I'm on the highway and ease into the gas until it downshifts. This is if I'm cruising at a somewhat slow speed (65 or so) with 3.42's the motor isn't turning real fast (less than 2k). No check engine light or codes other than an intermittent ABS light and code. Where should I start?
