I'm new to this forum and don't own a Honda but have many in our family. Recently my brother in laws Odyssey transmission started to slip at first in third and fourth gear then lost all forward gears. I understand that there are widespread problems with the early Odyssey transmissions but all I have read was that the fix was always just replacing trans. I was just wondering if anyone has any input as to what the cause of the problem is and if there is any particular part/parts failing. I am considering pulling it and fixing it for him and any experienced input would be greatly appreciated.
