How To Replace Automatic Transaxle

Automatic Transaxle Replacing On Chrysler 300M

For Manual Transaxle replacing click here

Automatic Transaxle Removal Procedure Is As follows:----

Don't Ignore The WARNING: 

Allowing the CV-joint assemblies to dangle unsupported, or pulling or pushing the ends, can damage boots or CV-joints. Always support both ends of the halfshaft to prevent damage or disengagement of the Tri-pot joint.



Before servicing the vehicle, make sure you take proper Precautions.

Remove or disconnect the following parts mentioned below:

• Negative battery cable
• Front wheels
• Front caliper assembly from steering knuckle
• Front brake rotor from the hub
• Speed sensor cable routing bracket from strut assembly
• Hub and bearing-to-stub axle retainer nut

Once the mentioned components are removed ...............
Install a puller tool onto the hub and bearing assembly and secure it into place using the wheel lug nuts.

Protect wheel stud threads by installing a wheel lug nut onto a wheel stud. Use a flat-bladed prying tool to prevent the hub from turning. Using the puller tool, force the halfshaft outer stub axle from the hub and bearing assembly.

Outer Cv-joint Has to be removed very carefully.The Diagram Below Shows How To Remove Cv-joint:

Fig. Be careful not to damage the threads for the axle nut when removing the outer CV-joint from the steering knuckle-halfshaft service

The Helpful Summary Of How To Exactly Perform This Disassembly:

Please Don't Ignore the Important Notifications And Warning Mentioned.

Dislodge the inner Tri-pot joint from the stub shaft retaining snapring on the transaxle. To do this, insert a prybar between the transaxle case and the inner Tri-pot joint and pry on Tri-pot joint.

NOTE
Do not try to remove the inner Tri-pot joint from the transaxle stub shaft at this time. Only disengage the inner Tri-pot joint from the retainer snapring.


Remove the strut assembly-to-steering knuckle attaching bolts from the strut assembly.

WARNING
The strut assembly-to-steering knuckle bolts are serrated (toothed) where they go through the strut assembly and steering knuckle. When removing the bolts, turn the nuts off the bolt; do not turn the bolts in the steering knuckle or damage to the steering knuckle will result.


Separate the top of the steering knuckle from the lower end of the strut.

Hold the outer joint assembly with one hand. Grasp the steering knuckle with the other hand and rotate it out and to the rear of the vehicle, until the outer CV-joint clears the hub and bearing assembly.

WARNING
When removing the outer CV-joint from the hub and bearing assembly, do not allow the flange disc on the hub and bearing assembly to become damaged. If this happens, dirt and water can enter the bearing, which will cause premature bearing failure.


Remove the halfshaft inner joint from the transaxle stub shaft by grasping the inner Tri-pot joint and the interconnecting shaft and pulling both pieces at the same time. Take care not to pull on the interconnecting shaft to remove or separation of the spider assembly will occur.

Once all the part is out then clean the dirty part,service the parts and replace the faulty worn out broken/damaged parts.

After that the simple and easy procedure To install:

Install the Tri-pot joint side of the halfshaft by performing the following procedure:

• Replace the inner Tri-pot joint retaining circlip and O-ring seal on the transaxle stub shaft. These components are not reusable and must be replaced whenever the halfshaft is removed.

• Apply an even coat of grease on the splines of the inner Tri-pot joint, where the O-ring seats against the Tri-pot joint.

• Install the halfshaft through the hole in the splash shield. Grasp the inner joint in 1 hand and interconnecting shaft in the other. Align the inner Tri-pot joint spline with the stub shaft spline on the transaxle. Use a rocking motion with the inner Tri-pot joint to get it past the circlip on the transaxle stub shaft.

• Continue pushing the Tri-pot joint onto transaxle stub shaft until it stops moving. The O-ring on the stub shaft should not be visible when the inner Tri-pot joint is fully installed. Check that the inner Tri-pot joint is locked in position by grasping the inner joint and pulling. If locked in position, the joint will not move on the stub shaft.

Hold the outer CV-joint assembly with one hand. Grasp the steering knuckle with the other and rotate it out and to the rear of the vehicle. Install the outer CV-joint into the hub and bearing assembly.

Install or connect the following:

• Top of the steering knuckle into the strut assembly. Align the steering knuckle-to-strut assembly mounting holes.

• Strut assembly-to-steering knuckle attaching bolts. Install the nuts to the attaching bolts and while holding the bolt heads, torque the nuts to 125 ft. lbs. (170 Nm). Turn the nuts on the bolts. DO NOT turn the bolts.

• New hub and bearing assembly-to-stub shaft retainer nut. Tighten but do not torque the nut at this time.

• Speed sensor cable routing bracket and screw

• Brake rotor and caliper assembly; then, tighten the caliper guide pin bolts to 30 ft. lbs. (41 Nm)

• Front wheels and lug nuts

• Negative battery cable

Once all the process is done then test the brake.It should be firm tight like original.Pump the brakes until a firm pedal is obtained.

Apply the brakes and torque the new stub shaft-to-hub and bearing assembly retainer nut to 120 ft. lbs. (163 Nm).

WARNING
When tightening the stub shaft retaining nut, be careful not to exceed the maximum torque specification of 120 ft. lbs. (163 Nm). If this specification is exceeded, failure of the halfshaft could result.


Road test the vehicle to check for noise or vibration.

How To Remove Transaxle on Chrysler 300M?

Chrysler Transaxle Removal

4 Speed Transaxle Description:--

The 42LE four speed transaxle uses fully-adaptive controls. Adaptive controls are those which perform their functions based on real-time feedback sensor information. The transaxle is conventional in the use of hydraulically applied clutches to shift a planetary gear train. However, it uses electronics to control virtually all other functions. Note that the factory recommends that before attempting any repair on the 42LE four-speed automatic transaxle, always check for proper shift linkage adjustment. Also, check for diagnostic trouble codes with the Chrysler DRB scan tool.

Use MOPAR Type 7176 Automatic Transmission Fluid only. Do not substitute transaxle fluid. If the differential sump requires fluid, use 80W-90 petroleum based Hypoid gear lubricant.

Before servicing the vehicle, make sure you take proper Precautions.

CAUTION: Be careful of sharp edges cowl/wiper area.

Remove or disconnect the following: 

• Negative battery cable
• Wiper blades
• Right and left wiper module covers
• Steel cowl/strut support

• Engine air inlet tube
• Transaxle harness connectors at cowl area
• Upper bell housing studs
• Loosen clamps at intersection of rear exhaust system to front catalytic converter pipe
• Rear exhaust from left catalytic converter pipe and right extension pipe
• Rear exhaust system
• Nuts securing the exhaust pipes to transaxle mount
• Loosen clamp at right extension at right catalytic converter
• Right extension
• Crankshaft Position (CKP) sensor connector and remove sensor. The sensor is located on the upper right side of the transaxle bell housing.
• Dipstick tube
• Gear selector cable from the transaxle
• Transmission range sensor connector
• Input and output speed sensor connector
• Transaxle cooler lines from the transaxle and plug them
• Lower control arm pinch bolts
• Lower control arms from steering knuckles by prying them out

Use a prybar to separate the inner tripod joints from the transaxle

   Fig. The halfshafts do not have to be completely removed from the vehicle.

Pull the bottom of the knuckles and halfshafts outward to allow clearance during transaxle removal. The halfshafts do not have to be completely removed from the vehicle. 

WARNING:  Do not let the halfshafts or CV-joints hang unsupported. Internal joint damage may result if allowed to hang free.

Remove or disconnect the following: 

NOTE:  Matchmark the installed position of the torque converter to the flex plate before removal.

Heated Oxygen Sensor (HO 2 S) wiring and left catalytic converter pipe.

Starter bolts and position it between the engine and transaxle. Do not disconnect the wiring or completely remove the starter.

Engine oil pan cooler.

Torque converter bolts and discard them. New bolts must be used during installation.

Use a transmission jack to slightly raise the transaxle, removing weight from the rear transaxle mount. 

NOTE
The crossmember bridge bolts are different lengths for each side, so note their locations during removal.


NOTE
Lower the rear of the transaxle to access to the bell housing bolts.

• Side bell housing bolts
• Dipstick tube from the transaxle and plug to prevent leakage
• Solenoid/pressure switch assembly connector from the top of the transaxle
• Transaxle by lowering it from the vehicle.

The procedure to install:

To prevent damaging the structural collar, hand-tighten all fasteners before torquing them to specifications.
If the torque converter is being replaced, apply a light coat of oil to the crankshaft pilot hole.
Check the drive plate for cracks before reinstalling the transaxle and replace the plate as necessary.
Use new torque converter-to-drive plate bolts, as different year models use different bolts.
Installation is the reverse of the removal procedure, noting the following torque specifications:

• Converter-to-driveplate bolts: 65 ft. lbs. (88 Nm)
• Driveplate-to-crankshaft: 70 ft. lbs. (95 Nm)
• Engine-to-transaxle case bolts to 75 ft. lbs. (101 Nm)
• Input and output speed sensor-to-case bolts: 20 ft. lbs. (27 Nm).

Fill the transaxle with fluid. Start the engine and allow it to idle for 2 minutes. Apply the parking brake and move the selector through each gear position, ending in N . Recheck the fluid level and add if necessary. Be sure the vehicle is level when refilling the transaxle. Use Mopar Type 9602 Automatic Transmission Fluid (ATF+4) only. Do not substitute transaxle fluid.

Check the transaxle or proper operation. Adjust the shift linkage, if necessary. Be sure the reverse lamps come on when in reverse.
