LQ4 Throttle body
Looking for a little help I have 2003 silverado 1500 hd and am having a problem with the throttle going away but not saying the reduced power I have also noticed that the trans shifts odd when this happens. The truck did fine all winter long now that it is getting warmer out its acting up again. So I found a used TB off a 2005 2500 hd with 15k and would like to try it. Does any buddy know if it will interchange.
Thanks, Bobby

it has thrown a few codes of TB. I would like to know what tells the tranny to shift I assume it is the throttle position sensor. My bully dog shows throttle position changing but MAF does not change. Looks like intake temps around 90 affect it. If I bump the throttle pedal a few times it wakes up. Has me stumped.
