For years on this list and type2 I've read over and over about how great Redline MT-90 is in a manual trans. Months ago I ordered some online (could not find it locally). Finally got the time this morning to change the trans gear oil to Redline. All I can say is "holy crap!", this stuff is all I've heard it to be. Not a fun job to do on a chilly day in your driveway, but well worth the effort.  Jeff
