Yes I’m reusing the photo

So it looks like my schedule and the weather may actually align this weekend so I’m planning on getting some maintenance and detailing done on the Accord. I’ve seen some people on online forums say that GM Synchromesh is the way to go with Honda MTs rather than the oem Honda fluid. Does anyone here have any prior experience with this? The trans shifts pretty good as is (sometimes 2-3 is a little notchy but not too bad) but with ~135k on the clock I figure it’s time  for a change so if the GM fluid will be better I’m willing to give it a shot.
