The FA4A-EL, FB4A-EL and GF4A-EL are 4-speed electronically controlled automatic transaxles that incorporate 5 multi-disc hydraulic clutches, 2 one-way clutches (sprag and roller type) and a friction lined brake band that prevents rotation of sun gear drum. See Fig. 1 .
ON/OFF and duty cycle solenoids control shift changes, line pressure and torque converter lock-up. Solenoids are attached to valve body. Solenoids are operated by either Transmission Control Module (TCM) or Powertrain Control Module (PCM).
TCM or PCM receives information from various input devices and uses this information to control solenoids for transaxle shifting, line pressure, shift feel and torque converter clutch lock-up.
Fig. 1: Cut-Away View Of GF4A-EL Is Shown; FA4A-EL & FB4A-EL Is Similar

I have a seperate reply on the internet, but is this a single solenoid or seperate ones I need replace in the transmission or is this on top of the transmission in conjuction with the transmission cable connection to the transmission? Thanks again for your time!
