2009 silverado 1500, 4l60e transmission. I'm having issues with a transmission shudder/vibration when my a.c. is on and the truck gets up to about 3,000-3,500 rpm. Turn the a.c. off and there's no issues. I know it has to do with the "load" the compressor puts on but has anyone ever experienced this issue?? My truck has a Jasper engine in it with AFM delete and a rebuilt transmission. Original transmission was having the same issues with the new Jasper engine.
