Back in November <a href=https://www.yesterdaystractors.com/cgi-bin/viewit.cgi?bd=ttalk&th=2299211>I reported on my results with a product called 'Lubegard Shudder Fixx'</a>. It seemed to fix the shudder that had developed in our 2012 GMC Acadia. Last week we took a drive down to the Florida Keys and back, and it was clear the shudder was back. The Acadia is now in the shop for a transmission rebuild, so the fix was not permanent.
I wonder if when the problem first cropped up, I had done a triple fluid change and used the additive (as suggested by Hobo) it might have worked. That would have been simple enough to do on the Acadia, which has a drain plug on the transmission and no serviceable transmission filter.
