I found these two at NAPAonline.com
Transmission Control Solenoid w/ 4 Speed Trans Shift Solenoid
ECH TCS561 $31.49
Transmission Control Solenoid w/ 4 Speed Trans TCC/PWM Solenoid
ECH TCS552 $57.49
Maybe you should find a qualified trans shop to tackle this repair.
To answer the question of where this switch is, it is behind the side cover of your trans.
Basically you need to drop the sub frame, lower the trans on the driver side low enough to get the side cover off. Once the cover is off I think its attached to the valve body. I am not sure if this can be done on the garage floor. If you try this please post pics.
