One week after this service, my transmission failed. No fluid had been reaching it but there was no evidence of a leak. It cost three thousand dollars to repair. How does this relate? My father is a mechanic and I had him on the line to make sure jiffy lube didn't try and upsell me. They were none too pleased at the arrangement. Jiffy lube has been caught selling services never done, and ripping people off in a variety of ways. We heavily suspect my transmission fluid was drained at jiffy lube.
