My 2003 Ford Explorer won't go over 30mph

What is your question?

I just bought a 2003 Ford Explorer Sport XLT, 4.0L engine, 136,000 miles. Vehicle won't go over 30mph and ABS light is on. Is this a tranny issue or brake system partially locked? Getting it looked at next week. Please any ideas might help.

What makes this problem better or worse?

Not sure

How long has your 2003 Ford Explorer had this problem?
