What kind of transmission is in my 2002 Ford E-350?
I have a Super Duty with the 5.4L engine. I want to replace the transmission fluid with Amsoil and was wondering if it's even possible to completely drain the transmission and completely replace it with pure synthetic. I see some other posts explaining how to do it and I'm ready to get dirty. Any pointers? TIA
How can you be sure he has a 4R100? My 2004 E350 with 5.4 has a 4R75 according to the data plate. Unless Ford just developed the 4R75 in the last 2 years I would expect all 5.4s to have the same transmission. Also, why does synthetic cause shudder?
