I dropped it off this morning and it was shifting ok got up to speed no problem which is good since a logging truck was hugging my *** I left a not e with the trouble codes and see what they say. I tried grounding the positive but the lights still on
Thank you Roy. I only offered that advice based on 2 of the U codes he had given. I did a quick google search and found someone on the Caddy forum with 2 same codes, but the 3rd was different. Apparently disconnecting the battery and shorting the + cable to the ground did the trick.
