k1500 4x4 shifting issue
I have a 1998 k1500 with the 5.7 vortec that shifts normal most the time. The issue I'm having only surfaces when I get on it. My engine revs to over 5k rpm and does not shift without letting off the throttle. It does this every time I floor it to pass another vehicle but if I'm driving and acelerating at a slower rate it shifts fine. The motor and transmission is very strong, suggestions on what could cause this?

She wouldn't have a vacuum line to her tranny, she's got the same one you and I have, just a bit different, but all electronic. Try replacing the Vehicle Speed Sensor, I've been doing ALOT of reading on the C/K series, especially the Tranny/ T-Case part of it. Also check the Throttle Position Sensor.
