I only tow the TT in my sig 3-5 thousand miles per year. I switched to synthetic fluid and saw no difference. Next oil change I am going back to dino. Dino fluids have come a long way even in the last 10-15 years. Unless you tow the majority of the time or see temps above 200 on a reg basis I don't believe there is much if any benefit to using the synthetic, except it will make your wallet lighter. On the filters, I would change both of them. I don't care what Ford says, you should drop your pan anyway to look for debri and clean the bottom of the pan, so why not change the filter?
Questions about changing Trans Fluid & Filters
I had my transmission fluid changed at 35k at Ford and at that time they changed the internal filter and external inline filter. Now I have 76k on my truck and I am going to be changing the trans fluid again. I plan on following the steps in the FAQ and I don't plan on changing the internal filter. My question is do I need to replace the external inline filter? If so, can I get them some where besides Ford? Does anyone have a part number for the filter if I get it elsewhere?
One more question, can someone explain the benefits of Synthetic trans fluid over dino? I don't tow anything and my trans temps never gets over 190, so is it worth it for me to use Syn. Fluid? Does it help performance wise?
Thanks
