I have a 1992 crown vic, it shudders, but not like the 30-50 mph shudder that
is a common problem. It shudders in 1st, 2nd gear but not that much in 3rd
and not in 4th.
It has lost LOADS of power, doesn't down shift into 2nd and engine hardly
responds under up hill load and if engine does respond on up hill, heavy
shuddering occurs along with sporadic clicking sounds as if something is
hitting the TC pan

just had some solenoids replaced. Yesterday I put in some Lube Guard and it
got a little better but I don't expect it to last. The tranny fluid is a good
