Stellar Automotive Group 4R100 Lockup Conversion Kit PWM to On-Off fits Ford 98-02

Stellar Automotive Group 4R100 Lockup Conversion Kit (PWM to On-Off) – Compatible for Ford Super Duty 1998-2002

End torque converter shudder, harsh lockup, and recurring solenoid failures forever with this proven PWM to on-off lockup conversion kit from Stellar Automotive Group.

The factory PWM (pulse-width modulated) torque converter clutch system in 1998-2002 4R100 transmissions is notorious for causing shudder during light throttle lockup, overheating, and early TCC solenoid burnout — often triggering P0741 codes and expensive repairs. This complete conversion kit replaces the problematic PWM solenoid with a reliable on-off design, delivering instant, firm lockup without modulation for smoother highway driving and better fuel economy.

Perfect fit for 1998-2002 models including:

• Ford F-250, F-350, F-450, F-550 Super Duty
• Ford Excursion & E-Series vans
• All 7.3L Power Stroke Diesel with 4R100

Benefits of the conversion:

• Eliminates converter clutch shudder completely
• Stops repeating TCC solenoid failures and codes
• Improves towing performance and transmission cooling
• Simple bolt-in installation with included harness adapter

Easy installation – drop the pan, swap the solenoid, connect the adapter harness, and enjoy shudder-free lockup. No tuning required.

Note: All parts are distributed, not designed or manufactured, by Stellar Automotive Group.
