How and where can I reset the TCM

The TCM is integrated into the power-train control module (PCM). Here is the official description: Electronic System Description:
The Power-train Control Module (PCM) and its input/output network control the following transmission operations:
shift timing.
Line pressure (shift feel).
Torque converter clutch.
The transmission control strategy combined with the engine control provides optimum power-train operation under all conditions. When determining the best operating strategy for transmission operation, the PCM uses input information from certain engine-related and driver-demand related sensors and switches.
In addition, the PCM receives input signals from certain transmission-related sensors and switches. The PCM also uses these signals when determining transmission operating strategy.
Using all of these input signals, the PCM can determine when the time and conditions are right for a shift, or when to apply or release the torque converter clutch. It will also determine the pressure needed to optimize shift feel. To accomplish this the PCM uses three pressure control, one torque converter clutch, and four shift solenoids to control transmission operation.
The following provides a brief description of each of the sensors and actuators used to control transmission operation.

Power-train Control Module (PCM)
The operation of the transmission is controlled by the Power-train Control Module (PCM). Many input sensors provide information to the PCM. The PCM then controls the actuators which determine transmission operation.

The main issue with these is the servo bore gets worn out due to the difference in metal type between the servo rod and the case so over time the servo doesn't actuate the band hard enough and causes the band to slip, overheat, then eventually break. There is a company that specializes in repair parts for these servos, fordservoboretransmissionfixsolution. Com is their website. This repair should be done at the same time the band or any other part is replaced. As far as difficulty level, I wish I could say it's easy to replace this band but, non way would that be true! It's step 67 in the tear-down procedure just to get to it! There are excellent videos for this transmission tear-down online so I wouldn't be doing you a favor giving you over 100 pictures and documents, but I can get you the torque specs if you get to that point.

Rockauto. Com is pretty good because they give you multiple options for kits.

Anytime my friend! We're here for you because we've all been there!
