I would really appreciate your opinions on this. I have a 2003 Honda Odyssey which many know have a weak auto trans notorious for high failure rate.

I have been running Amsoil Uni Synthetic ATF for some time coupled with a Magnefine In-line tranny filter. This combo I believe has allowed me to get so far 178,000 miles on the original tranny which is not the norm for these transmissions. The other day I did a ATF drain/fill and noticed more "stuff" on the drain bolt magnetic plug than fact normally I do not see anything on it. This time I did see more than normal which is alarming to me.

1) Question: How did this get by the Magnefine?
2) Question: Is this a sign that the Magnefine needs to be changed? It has only been in the vehicle for 10,000 miles.
3) Question: If I have a Magnefine installed is it even worth changing the OEM ATF filter? I have not changed it yet because of the oil jet recall making it more complicated to do so.

I know I am on borrowed time so perhaps this is the beginning of the end of my original tranny.

Thank you for your help.

You have 178k on the transmission and you are now considering a cooler. For some reason some people here think the cooler is the majic answer to all the Honda transmission problem. The only I would put on an after market cooler is if I was towing or someone in the family has a lead foot. What did the transmission fluid look like? If it was worse than normal I would do a 3 or 4 drain and fill to clean it up. The magnifine will help clean some but it foes not get all the fluid flowing through it as all the flow is not through the cooling tube. Was the gunk on the plug metal or just gunk?
