I have a question for all the Ody experts out there. Reading from other posts, I see that the 1st gen Ody's 4-speed transm does not have the transm filter. So I can see why you would install a magnefine filter. However on the 2nd gen ody, which is what I have, do you really need to install the magnefine even though there is already a ATF filter that you can change out? I am getting ready to change out the ATF filter but I need to decide if the magnefine is really needed on a 2nd gen ody.
