This answer was rated:

I have a 2000 f250 5.4L automatic w/OD. Trans shifts hard going into 3rd gear. Any ideas?


Do you have any lights on, check engine or Overdrive light flashing?

Is this your only concern harsh shift into 3rd?

How does the transmission fluid look?

Customer: replied 7 years ago.
check engine light is on . code is for oxygen sensors.this is also a concern because the sensors are new but light comes back on. trans fluid looks and smells fine.other than 3rd gear hard shift trans works fine

Vacuum leaks can cause O2 sensor codes.

Here is a list of possible causes for harsh 3rd shift. The most likely of which would be the direct clutch accumulator valve, 2-3 shift valve springs. There are many possibilities that can cause this concern.
