my 92 rs 305 radiator blew and mixed with the antifreeze with trans fluid and turned into a nasty shake. what is the best way to flush the trans?
thanks for the help.

Take the trans apart, the clutches' friction material is glued on with water based glue, This is your first problem, the 2nd is you will never remove all water, some will form "mayonaise" and nestle in nooks and crannies, it won't flush out....thirdly, internal parts will start rusting, even if you pump fresh ATF through it
