Old, Closed Accounts Good or Bad on Credit Report?

[Mark Beekman]

I just checked my FICO scores and I have a 737 from Transunion and a 755 from Equifax. Transunion has a few accounts listed as "open accounts" that Equifax does not and I'm wondering if that is why the score is lower. The "open accounts" in question are actually closed accounts (ie. a car loan that was paid off years ago).

Would it be beneficial or detrimental for me to contact Transunion about these old accounts? The accounts are being shown to carry a $0 balance and are listed as "Paid or Paying as Agreed", however it shows the payment history ending in early 2008 when I paid the loan off.
