Probably an engine issue. Does the trans shift hard, or does it slip? Does the converter lock up shortly after a downshift? (Watch RPM's)
Drivetrain problem - shudder/ vibration @ 55 - 60 mph
Hi,
I have a 2000 F250 4x4 that does not seem to run with the same vigor it used to, seems to take longer than usual to shift to the higher gear and also seems to vibrate between the 55 - 60 mph ( smooths out at 70+)
At all speeds it seems like an imaginary very heavy load has been hooked to the truck
Engine seems to run fine, idles fine starts up easy,
What could it be? No check engine lights..
