2003 4r70w
Greetings all,
I just purchased a 2003 F150 Supercrew 5.4L with the 4R70W trans and 20,500 miles.
The transmission shifts just as smooth as glass up and down the gears. So smooth that sometimes I never notice the shifts.
The problem I am having is during braking. At the last second just before dead stop, I'll hear and feel a 'thunk' (thud and clunk) from either the transmission or somewhere else in the drivetrain. If also feels as if the tranny has a sudden last second surge in power just before dead stop even though my foot has been on the brake the entire time.
If I come to a stop and I'm using a feather touch on the brake very very slowly rolling to a complete stop there is no problem felt or heard. But, under normal braking conditions, just before dead stop I get that 'thunk'.
Has anyone else experienced this or have an idea of what might be the problem? Am I headed for a serious transmission problem or is this just indicative of this model vehicle.
Thanks in advance!
