Hi All,
I am new on this forum, hoping to find some answers and suggestions regarding my 02 Ford Explorer.
I have a question regarding the 5r55w and the 5r55s transmission models.
Can I replace my 5r55w for the 5r55s model?
What are the differences exactly?

Thanks soooo much in advance for your replies

Welcome to this forum! I've moved your thread into the transmission section. Take a look at the 5R55S swap sticky thread on the top of this section.
Where do I find this exact thread because I am in this same boat


For high performance applications, do the 6R80 trans, and rewiring with a 2014 F150 PCM, plus tuning, probably $3500 easily.
