Thanks TiAgX5 for your reply. I've updated the original post to include the correction.
When you changed it at 100K, did you do a drain and fill or was a drain, fill, then drain again and fill? I'm being told by many that this is the way to do it if you don't want your transmission to fail due to the mixture of the old and new fluids. If you ask me, logically it would make sense to do it the other way and leave half of the old fluid inside to mix with the new to ease off the "shock" the tranny may feel but I can understand the other side of the argument as well.
My mechanic wants to do this for $500 but I'm going to give it a go myself for $170 in parts. Febi OEM fluid and Febi OEM transmission filter, gasket, etc. What he mentioned was if he drops the pan and sees a lot of wear on the magenets, he's going to seal it right back up and put the old fluid back in there again. I figure I'll do the same but how much is too much?
After 100k, do you recall if your magents inside the pan were extremely heavily covered with buildup or was it normal looking (some buildup).
Can't wait to get this over with and take a nice long road trip somewhere to put my mind at ease!
