Overhaul - V4AW2: Description
Transmission has 4 forward speeds (4th is overdrive) and reverse. Gearshifts are determined by engine load, selector lever position, throttle valve position and output shaft speed. Components include a governor, torque converter, forward clutch, direct clutch, overdrive (OD) clutch, planetary gears and transfer case. See Fig 2 . For transfer case overhaul information, see appropriate article in AXLE SHAFTS & TRANSFER CASES section.
An Overdrive (OD) switch is mounted on the shift lever. When OD switch is depressed to ON position, transmission will shift into 4th gear when shift lever is in "D" position, and OD OFF light on instrument panel will go off. When OD switch is released to OFF position, transmission will shift into 3rd gear, and OD OFF light on instrument panel will illuminate.
A pattern select switch (if equipped) is located near shift lever on center console. Pattern select switch contains a POWER (PWR) and a HOLD operating position. When pattern select switch is depressed (PWR position), transmission upshifts and downshifts will occur at a higher vehicle speed than with switch released. An indicator light on instrument panel indicates pattern select switch is in PWR (on) position.
Transmission is equipped with a shift lock and key interlock system. Shift lock system prevents shift lever from being moved from Park unless brake pedal is depressed. Key interlock system prevents ignition key from being moved from ACC to LOCK position on ignition switch unless shift lever is in Park.
