no damage to transmission noted yet, 2004 honda oddessy code 0740
torque converter clutch defective, , do I need a new transmission on 2004 Honda Odyssey
Are you still driving it? If so , Try a drain & fill (WITH HONDA ATF-About 4 quarts needed) that may get some more life out of it. The only true fix for that code is (technically) to replace the trans. If it was mine I would drive til' it dies , BUT do fluid changes every 20-25K miles may help.
