Apply Components
APPLY COMPONENTSIntermediate and Overdrive Band
The intermediate and overdrive band assembly holds the reverse clutch drum assembly to the transaxle case in second and fourth gear. This action causes the reverse/overdrive sun gear and shell assembly to be held stationary in second and fourth gears.
Intermediate and Overdrive Servo
The intermediate and overdrive servo is the hydraulic actuator which applies the intermediate and overdrive band assembly. Line pressure is applied through the servo apply circuit where it works on one side of the servo piston. This forces the piston to move up the servo bore in the transaxle case, which moves the servo apply rod against one end of the intermediate and overdrive band assembly. Because the other end of the intermediate and overdrive band assembly is anchored to the transaxle case, the ends of the intermediate and overdrive band assembly are squeezed around the reverse clutch drum assembly, holding the reverse clutch drum assembly stationary.
Forward Clutch
The forward clutch connects the turbine shaft to the outer race of the forward one-way clutch, which in turn drives the low/intermediate sun gear in all forward gear ranges. However, in fourth gear, the forward clutch transmits no power because the forward one-way clutch is overrunning. The forward clutch is a mull-disc clutch and is contained in the forward/coast/direct clutch cylinder assembly.
Direct Clutch
The direct clutch connects the turbine shaft to the low/intermediate ring gear assembly when the vehicle is in third and fourth gears. It is a multi-disc clutch and is contained in the forward/coast/direct clutch cylinder assembly.
Reverse Clutch
The reverse clutch connects the turbine shaft to the reverse/overdrive sun gear and shell assembly when it is in reverse gear. It is a multi-disc clutch, and is contained in the reverse clutch drum assembly.
Coast Clutch
The coast clutch is a multi-disc clutch located beneath the forward clutch in the forward/coast/direct clutch cylinder assembly. It connects the low/intermediate sun gear assembly to the turbine shaft assembly when the transaxle control switch is ON in the DRIVE position or when any manual gear is selected.
Low/Reverse Clutch
The low/reverse clutch holds the reverse/overdrive carrier assembly to the transaxle case when the transaxle is shifted into the R or 1 position. The low/reverse clutch is splined to the transaxle case and is a multi-disc clutch.
Forward One-Way Clutch
The forward one-way clutch is a sprag type, one-way clutch. The forward one-way clutch combines with the forward clutch to connect the turbine shaft assembly to the low/intermediate sun gear assembly in first, second, and third gears. The forward one-way clutch overruns during all coasting operations and is always overrunning in fourth gear.
Low One-Way Clutch
The low one-way clutch is a roller type one-way clutch which allows the transaxle case to hold the reverse/overdrive carrier stationary when the transaxle is in first gear. The low one-way clutch will only hold the reverse/overdrive carrier assembly during acceleration. When coasting, the low one-way clutch will overrun, disconnecting the final drive from the compound planetary gearset.
GEARTRAIN
The geartrain includes the planetary gearsets, apply components, and final drive gearset and differential.
Planetary Gearsets
The automatic transaxle has two planetary gearsets to provide operation in reverse and four forward speeds. The gearsets are comprised of the following components:
^ Low/intermediate sun gear assembly.
^ Low/intermediate carrier assembly.
^ Low/intermediate ring gear assembly.
^ Reverse/overdrive sun gear and shell assembly.
^ Reverse/overdrive carrier assembly.
^ Reverse/overdrive ring gear assembly.
Drive Chain Assembly
Drive Chain and Sprockets
A chain drive transfers torque from the torque converter turbine to the planetary gearsets. The chain drive is composed of the following components:
^ reverse/overdrive ring gear assembly which acts as a drive sprocket
^ driven sprocket
^ drive chain
The drive chain connects the reverse/overdrive sun gear with the driven sprocket. The final drive sun gear located on top of the driven sprocket meshes with the final drive gearset.
The final drive consists of a planetary gearset that transfers and multiplies torque from the planetary gearsets to the differential. The final drive consists of the following components:
^ Final drive sun gear: is chain driven by the reverse/overdrive ring gear assembly and transfers torque to the final drive carrier.
^ Final drive carrier: the final drive carrier acts as the driven member and is part of the differential case.
^ Final drive ring gear: is held by the converter housing and is always the held member of the final drive planetary gearset.
Differential
The differential assembly drives the differential pinion gears and the differential side gears which in turn drive the front wheel driveshaft and joints, and provides differential action if driving wheels are turning at different speeds. The differential assembly consists of the following components:
^ differential case (part of the final drive carrier)
^ two pinion gears supported by a pinion shaft
^ two side gears supported by the differential case
