Where in the transmission is the transmission control solenoid on 2000 f150 located

Inside the transmission . Which shift solenoid ? 1 - 2 , 3 - 4 , 2 - 3 ?
The shift solenoid valves are two identical, normally open, electronic exhaust valves that control upshifts and downshifts in all forward gear ranges. These shift solenoid valves work together in a combination of ON and OFF sequences in order to control the positions of the 1-2, 2-3 and 3-4 shift valve trains. The PCM monitors numerous inputs in order to determine the appropriate solenoid state combination and the transmission gear for the vehicle operating conditions.

Most modern electronic controlled auto transmissions have shift solenoids located underneath the bottom pan. Remove pan and inspect for a solenoid coming apart. Easy to replace.

They are in the transmission . Remove the transmission fluid pan. You will see the valve body , the solenoids are mounted to it. They are clipped in. Do not remove the valve body unless you have to. Things pop out of it. Be careful removing solenoids, things can pop out of these holes also. Hold the solenoid and remove the clip/s.

The Pressure Control Solenoid is part of the EVAP system, not the transmission. It is located just forward and to the outside of the brake master cylinder. See the attached image for location. Replace it and you should be good to go.

All of the transmission shift solenoids are located inside the transmission and are attached to the transmission valve body hydraulic control plate.

Inside the transmission.

There are several control solenoids in the transmission, They are located inside the transmission and you need to remove the oil pan to get to them.

whether it is the smaller (4R70w) or the bigger (E4OD), the solenoids are under the pan. The E4OD solenoids are in one big block where the other trans has them seperated

the 4th gear shift solenoid locks the gear into place
It is weak now so a replacement is needed
It is located inside the transmission and is easy to access it once the bottom pan is removed

Your shift solenoids are mounted in the valvebody of the transmission. That particular transmission is a 4L60E in case you need to know.
