00 Expedition trans shifts late and hard

find a tranny man,
any ASE shop works
ask em.' to CHeck it out.

You don't give me much information to work with. However, 1st, look at the engine mounts. You may have a broken mount. This will make it feel like the transmission is shifting hard. Other than that, there is only a few things that will cause this. The speed sensor tells the computer when to shift the shift solenoids. It may not be "seeing" a quality signal. If this is the case, the speedometer will be bouncing too. Last idea is that it is skipping a gear. Starts in 1st, should go to 2nd at about 10 MPH. 3rd at 25 to 30 MPH. And, if you have a Overdrive transmission, it should go into overdrive at around 45 to 55 MPH. If it is skipping 2nd, it will engage 3rd at a high engine speed, and will feel like a sudden slam into gear. If this is true, your transmission needs some work. Hope this all helps. Good Luck.

If it's in limp in mode it won't shift out of 2nd gear. Get the trouble codes read. The solenoid pack is a pretty common failure. But don't just throw parts at it. Get the codes first.

no problems before the mud deal but problems after the mud deal means that the problems started in the mud
check for mud in connections , wires disconnected , harness problems, vacuum hose to actuator broken or missing
run the fault codes to help point to a problem area
the transmission is sealed so there will be no need to change the oil or filter--just clean and check everything that is mud affected

That is called overdrive. You have an electronically controlled transmission, so you must have the control module checked for codes with a special tool called a scanner.

Throttle position sensor, speed sensor. To start. Probsbly the TPS

You remove and clean the valve body

No luck,you rebuild the unit

I used to own a trans shop

Are you sure the trans is in 3rd. Pull the stick into low gear accelerate shift to 2nd about 20 mph shift to 3rd about 35 mph then 4th about 50 mph. This will let me know how to go further with your problem. If you do this proceedure write the results on this Great FixYa Page!

Yes you need to have it adjusted.
