My wife has a 2004 Honda Accord which is approaching 80k miles and wondering if I may be doing more harm than good by having the auto tranny flushed and refilled with new fluid. I have been getting mixed answers on this question and would like to know what your thoughts are.
Typically 80k can be in the "ok" range to flush. This decision really should be based upon current condition of transmission fluid. If it is dark brown/black it is not such a good idea anymore as that condition in the industry is "too far gone". When fresh fluid is ran through a transmission that has prolongation of such fluid, air enters and becomes foam. Foaming WILL cause a transmission to fail at an exponential rate.

Honda reccomends the transmission be serviced the first time at 60,000 miles and every 30,000 miles after that

Honda recommends at every 20,000 miles under normal conditions to have the transmission fluid drained and filled, not flushed. I would recommend to have a Honda certified facility check the condition of the fluid and advise accordingly.

If*and only if*the transmission fluid has been changed regularly (30 to 40,000 miles) it is safe to do so again. If not, do not change the fluid or flush the transmission. Transmission fluid is a "solvent oil". New transmission fluid can dissolve the adhesive used to bond the friction surfaces of the clutch discs and bands to the steel backing. This causes rapid failure of the transmission, requiring a complete overhaul. We have seen this done on old three speed automatics that use type F fluid with no harm done, but I definitely would not recommend it on any transmission built after 1982.
