is the AUX transmission pump supplied by the 12volt battery? it's confusing because it's a 14Volt 3 Phase A/C motor..



When i have the A/C running the Clutch slips and the engine ill just rev or SURGE as GM calls it...
it also happens when you take your foot off the brake peddle.. an not pressing the gas..

as soon as i turn the A/C off the issue goes away....
sometimes it struggles on shift from first to second gear on a cold start or if the SUV had been sitting for a hour or two .. from what I read "first and second gear" is handled by the Auxpump... other wise the transmission will shift all 4 gears smoothly and fast(I use M4 so i don't use AFM)
