I solved mine. Found a video on YouTube where the fellow showed that the ground for the trans? Runs to close to the alternator and it cause interference. Simply move it more out of the way and as for me it stopped the problem. Good luck.!

 

sometimes the fix requires a separate ground wire fromm the TPS to a good ground on ther frame. Also, when checking the battery connections, dont forget to check the ground wire connection at the grounding point. Make sure that isn't rusted or loose.
