Description

E4OD/4R100 Intermediate Servo Piston – Compatible for Ford Super Duty 1989-2004

Fix harsh 2-3 shifts, delayed intermediate band apply, and burnt bands with this upgraded molded intermediate servo piston from Stellar Automotive Group.

The factory cast piston with separate lip seal is notorious for cracking, hardening, and leaking over time — causing weak or no 2nd-to-3rd band apply in heavy-duty applications. This direct-replacement molded piston features a permanently bonded rubber sealing lip that stays soft and leak-free for decades, restoring instant, firm servo engagement every time — perfect for towing, diesel torque, or high-mileage rebuilds.

Perfect fit for popular models including:

  • Ford F-250, F-350, F-450, F-550 Super Duty
  • Ford Excursion & E-Series vans
  • 7.3L Power Stroke, 5.4L, 6.8L V10 applications (1989-2004)

Symptoms of a bad intermediate servo piston:

  • Harsh or delayed 2-3 upshift
  • Slipping or no 3rd gear
  • Burnt intermediate band on teardown
  • Servo cover leakage

Don’t fight old servo problems any longer — upgrade to the modern molded design and make your E4OD/4R100 shift crisp and reliable again.

Add this must-have E4OD/4R100 servo upgrade to your cart today and feel the difference on every 2-3 shift!
