You recommend the friction-modified GM fluid but you're using the non-modified in your Insight??
I already had the non-friction modified sitting around so I used it.
Really?? Where??
I searched for trans bearing and got 4 pages. Below is from the first page:
Trans Overhaul
Input Shaft Bearing Replacement
Oh boy - M.T. bearing availability
Trans Overhaul
If you really want to know the low-down on Honda MTF you will have to do a search on Honda-tech.com. and read. Trans bearings should last 400K at least. If they don't, somethings wrong.
I can't say for sure if trans fluid is a cause of syncros going out on transmissions because of the human factor but from what I've read the friction modified helps a great deal in that area also.
