Ford 4R100 Transmission
2004 Lincoln Aviator V8 with a 4R100 Transmission AWD
Just bought this vehicle and I notice a shutter when shifting, Sometimes and not others.
Seem to do it about the time it is shifting into 3rd or Overdrive. Seems to do it when not on the gas hard, but just gaining speed.
Sensor? Lockup torque? Sensor? Tranny service?
Best guess will point me in a direction Thanks
You can try changing the fluid first as this is the most economical. If the shutter is still there, your overdrive band is probably burnt requiring a rebuild or replacement. Have it diagnosed by a reputable trans shop or mechanic.
I forgot to mention that if I'm under a strong acceleration it shifts really good, Its just under a slower or moderate that it does this.
Did you ever find out the cause? I am having the same issue- same make/model as well.
