I have just read many old threads on trans fluid, some from over two years ago.
I'll outline where I'm at and take your suggestions. My 1999 F-350 has 130,000 on it. The transmission has 80,000 on it. I think when the new trans was put in the mechanic used Mobil 1. I have had the mechanic drain and fill the trans a couple of times now and I believe Mobil 1 has been used every time. I don't think a full flush was done, but only a drain and fill. I don't even know if the torque convertor was drained.
I'm going to tackle the task myself this time. I'm thinking I should replace the filter. Should I just drain the pan and torque convertor or try and do a complete flush? Do I use Mobil 1 or can I save some money with a generic Mercon V labled fluid and not notice a difference? Is the Mobil 1 that much better?
