Does chevy recommend to not change transmission fluid? The drain bolt wouldn't come loose with a 3/8inch impact and rounded off with a 1/2 inch impact. The mount bolts for the shift linkage which uses a torx rounded out. I was able to remove one bolt with a pair of channel locks and move it out of the way. This allowed me to drop the pan. I used a regular bolt to reinstall the mount in place. I plan on using a ziz wheel to resize the drain bolt to a 14mm or 13mm so it has a full length fit for the socket. I plan on changing fluid only when I do my next oil change. How much loctite are the using for these drain plugs to prevent fluid changes?
