Transmission Control Solenoid
Transmission Control Solenoid. Where is this located? Is this actually in the Transmission? Also does anyone know a way of flushing the transmission at home? Getting all of fluid out, including what'* in the torque converter? Thanks

Not really. There is a lot of detail just to get the side cover off. This older thread will give you an idea.

If you want to change your trans fluid, you can get about 7 or 8 of the 11 quart capacity by draining it. I ended up draining it - driving for 3,000 miles then draining it again. This will get about 90% of the old fluid out. I did it at the same time I changed the motor oil, for two times.
Using Sea Foam Trans Tune and replacing the filter, two times, will do a pretty good job.
I HIGHLY RECOMMEND doing a Shift Kit at the same time. It will likely eliminate the Pressure Control Solenoid problem altogether. It did for me. Also, your transmission will be MUCH happier (and so will you because the trans will shift like it should have all along).

and how will this fix the solenoid problem?
The Pressure Control Solenoid controls the engagement of the clutches by regulating the fluid pressure. The accumulator does this too. However the Pressure Control Solenoid can be controlled by the ECM, whereas the accumulator is purely mechanical. Therefore the ECM can use the Pressure Control Solenoid to "trim" the clutch engagement to regulate shifting.
When the Pressure Control Solenoid gets sticky (from normal clutch wear and residue in the fluid), the ECM apparently sees an error in the amount the clutches slip (this can lead to premature clutch failure) so it goes into a protection mode and has the clutch engage abruptly.
Installing a shift kit will change the accumulator so that the Pressure Control Solenoid is no longer "trimming" the clutch engagement because the accumulator has the shift be over with before it will (this my not be a technically accurate description, but you can get the idea).
How hard is the shift kit to install?

Do a search for "shift kit" and you'll get a lot to read...
