Default Drives great BUT if I turn on A/C and set it at 45 - 55 mph it acts like its slipping

Last month my truck was jumping around with the RPM so I took it to a transmission repair shop they told me the computer is doing what it needs to do and everything looks fine so after 4 days they gave it back to me with all new negative bat terminals they said it was a bad ground!
Well today ran my A/C and its back but only when my A/C is on and in High not med as much so I took it to two places and had the bats and alternator checked both said it in great shape nothing wrong with aether?? So I went home and started Grounding everything and twice I am a electrician and have all the parts I have probably 80 ft of #8 AWG and ground lugs on Transmission, Engine, Body, Frame even the Radiator!!! HA HA still doing it but I will say its not as bad SO WHAT SHOULD I DO NEXT????

RECAPE! Drives great BUT if I turn on A/C and set it at 45 - 55 mph it acts like its slipping RPM jump for a brief moment???

Thanks for the find! Looks like he is still throwing money at it! $62.50 for a noise filter sounds good to me but it just cant be a ground I dont think?

Does anyone know were I can find the Transmission ground or is it grounded through the Engine? I dont see anything???

ONE WORD DUDE!!!
Ok so I ran another ground jumper from engine block to Alternator and noticed a freshly taped connection on the neg bat one wire was to the alternator and the other I think to the A/C so I opened it up and two # 8 AWG under one #10 crimp or so it looked Thanks Bobby Transmission.
So respliced and runs like a champ so far!!!!
