1995,1996,1997,1998,1999,2000 Plymouth Breeze, Dodge Stratus, Chrysler Cirrus transaxle diagnostics and repair

Diagnose transaxle malfunctions follow these simple steps to help guide you through to help you guide you through procedures.

Automatic transaxle malfunctions may be caused by five general conditions

Poor engine performance.

Improper adjustments.

Hydraulic malfunctions.

Mechanical malfunctions.

Malfunctions in the computer auric signal network.

Diagnosis of these problems should always begin with the check of the easily repaired items. First, check the fluid level and condition, shift cable adjustment, and shift lever installation. Next, perform a road test to determine the problem has been corrected or if more diagnosis is necessary. If the problem persist after the coronary tests and corrections are completed additional diagnosis should be formed by dealer service department or other qualified transmission repair shop.

Preliminary Checks

Dry the vehicle to warm the transaxle to normal operating temperatures.

If the fluid level is unusually low, and the fluid ring level within the designated area of the dipstick, and check for external leaks.

If the fluid level is abnormally high, drain off the excess, then check the drain fluid for contamination by coolant. The presence of engine: an automatic transmission fluid in the case of a failure has occurred in the internal radiator oil cooler walls that separate the coolant from the transmission fluid.

If the fluid is foaming, drain it and refill the transaxle, and check for: fluid, or a high fluid level.

Checked the engine idle speed. If the engine is malfunctioning do not proceed with the plenary checks until it has been repaired and runs normally.

Check and adjust the shift cable if necessary.

If art shifting is experienced, inspect the shift cable under the center console and at the manual lever on the transaxle.

Fluid leak diagnosis:

Most fluid leaks are easy to locate visually. Repair usually consists of replacing a seal or gasket. If the leak is difficult to find, the following procedure may help.

Identify the fluid. Make sure his transmission fluid and not engine oil or brake fluid that is leaking.

Try to pinpoint the source of the leak. Drive the vehicle several miles, then park it over large sheet of cardboard. After after a minute or two, you should be able locate the leak by determining the source of the fluid dripping onto the cardboard. Automatic transmission fluid is a deep red color.

Make a careful visual inspection of the suspected component and the area immediately around. Pay particular attention to gasket mating surfaces. A mirror is often helpful for finding leaks in areas that are hard to see.

It's leak still cannot be found, clean the suspected area thoroughly with a degreaser or solvent, then dry it thoroughly.

Dry the vehicle for several miles at normal operating temperature and varying speeds. After driving the vehicle, visually inspect the suspect the component again.

Once leak has been located, the cause must be determined before it can be properly repaired. If the gasket is replaced with the sealing flange is bent, the new gasket will not stop the leak. The bit flange must be straightened.

Before attempting to repair a leak, check to make sure that the following conditions are corrected or they may cause another leak. Some of the following conditions cannot be fixed without highly specialized tools and expertise. Such problems must be referred to a qualified transmission shop or dealer service department.

Gasket leaks:

Check the pan periodically. Make sure the bolts are tight, no bolts are everywhere are missing, the gasket is in good condition and the pan is flat. Denson the pan may indicate damage to the valve body inside.

If the pan gasket is leaking, the fluid level or the fluid pressure may be too high, the event may be plugged, the pan bolts may be too tight, the pan sealing flange may be warped, the sealing surface of the transaxle housing may be damaged, the gasket may be damaged or the transaxle casting may be cracked or porous. If sealant instead of gasket material has been used to form a seal between the pan and the transaxle housing, it may be the wrong type of sealant,

Seal leaks:

If the transaxle seal is leaking, the fluid level or pressure may be too high, the event may be plugged, the seal bore may be damaged, the seal itself may be damaged or improperly installed, the surface of the shaft protruding through the seal may be damaged, or a loose bearing may cause excessive shaft movement.

Make sure the dipstick tube seal is in good condition and the tube is properly seated. Periodically check the area around the sensors for leakage. If transmission fluid is evident, checked the seals for damage

Case leaks:

If the cases self peers to be leaking, the casting is porous and will have to be repaired or replaced.

Make sure that will cooler hose fittings are tight and in good condition.

Fluid comes out of vampire or fill tube:

If this condition occurs the possible causes are, the transactional is overfilled, there is coolant in the fluid, the case is porous, the dipstick is incorrect, the vent is plugged or the drain back holes are plugged.
