IDENTIFICATION
Vehicle Identification Number (VIN) is used for correct application of component parts and assemblies. Number is on a plate located at top left of instrument panel and on transaxle flange (exhaust side of engine).
DESCRIPTION
The GF4A-EL is a 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. (Scheme 83)
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.
