at least once a year or every 10-12k miles is my plan... its cheap and worth it for the longevity of your diff & tranny.

yeah i think AHM says every year or 15k miles...more frequent changes could help the life a lot and avoid common problems imo.

I hear the GM synchromesh friction modified works best for tranny. Diff I am still researching.

yea i've heard mixed reviews, none bad though... the general idea that i got from my research was the gm synchro mesh helped a lot of people with the "notchy" feeling when shifting but the feeling came back after 5000+ miles or so. plus a lot of the people who complained about the notchy feeling were shifting while the tranny was cold...so i dunno what they were expecting.

everyone who uses the new honda mtf said the crunchy feeling went away too.. and red line made it go away etc etc.. so basically, i think its all the same more or less it just depends how often you change it that makes the real difference. the fresher the fluid the better. i switched to the new honda mtf and it helped my notchiness go away even when cold (still there, but much less).

honda recommends the change of tranny fluid at 120,000 miles.
And Differential every 30K miles.......considering normal conditions.
