Anyone experience this with there own F150? I just had it happen a little while ago while driving home from St. Cloud and I have just started my research online. Seems like this happens occasionally from my initial reading, but I have yet to fully research the probable diagnosis and method of correction. Initial comments talk about worn out transmission fluid corrected by a flush and fluid replacement.
As soon as the transmission shifts into OD at 45 m.p.h. it starts to shutter until 55 m.p.h. Accelerating past 55 m.p.h. the shutter subsides. Only happens during acceleration and does not happen during deceleration. Obviously requires a load. Babied it home.
99′ 5.4 +/- 135k miles automatic transmission obviously
Anyone experience this before?
