I recently purchased a new 2006 E350 SD Cutaway. 5.4 liter, Automatic,
Gas. When stopping the vehicle the transmission jerks as it
downshifts into first gear just as it is coming to a complete stop.
Thinking this was a defect, I returned it to the dealership and had
the technician determine that it was a sticking solenoid. The parts
were replaced but it still "jumps" as the transmission downshifts into
first gear. I asked to test drive another exact truck on the lot and
it is worse than mine. The techs and advisors have heard of no
problems like this from other customers but I have never driven a
vehicle that does this. Does anybody have any clues, or is this just
inherent of the Ford Transmission?
This is a cutaway so do you have a body on the back yet? If not, that might
also be a source of your problem. You have no weight back there to keep
traction on your rear wheels when stopping. Start stopping sooner than you
normally would, and use less brake pressure, this will keep the vehicle from
nose diving and keep some weight on the rear wheels. See if that doesnt help
Also, these trans have whats called adaptive strategy in them. Meaning they
learn how you drive, and adapt shift patterns as such. It sounds to me like
the 1st gear clutch is coming in too fast. I still want to know what kind of
weight is on the back of this thing.
