  2. Pretty much the same

    T-45
    1 - 3.37
    2 - 1.99
    3 - 1.33
    4 - 1.00
    5 - 0.67

    T-3650
    1 - 3.38
    2 - 2.00
    3 - 1.32
    4 - 1.00
    5 - 0.68

    2003+ T-3650's have a 0.62 5th gear.
     
  3. Thank you man :nice:
     
  4. Really?
     
  5. Yup, i have a huge jump in RPM when i shift from 4th to 5th. To make it smooth i need to let the RPM's come down a bit before letting out the clutch.

    Apparently Ford changed all their O/D gearing in 2003 to meet EPA standards.
     

  6. Yep. Makes driving with 4.10's on the E-way a lot nicer and eaiser on the wallet. :nice:
