Transmission troubles
Hi first time user, I have a 2000 F150 4x4 SC 5.4L, Noticed that the transmission shifts hard from 1-2, replaced the trans. oil and filter 40 000km ago, this just started, if you start out and throttle the gas the shift takes too long, rpm climbs to 4000 rpm before shifting, if you ease into the throttle the shift is normal, if you are at hiway speeds and throttle the gas down it neutralizes the trans, until you ease up on it, can any one help!

Welcome to the forums 
You need to drive it with a scan tool to watch to see if the PCM is telling the tranny to shift. Have you checked for codes yet?
I have seen the gear selection switch on the tranny go bad and cause some wierd things. The computer doesn't know what gear it is in.

Well!!! I found out why the SES light was on # 5 coil was breaking down, so I replaced it but the transmission was something else, the springs by the servo piston broke, and this locked up two clutches at one time thus the I had no choice but to have the transmission rebuilt and new torque installed.
