You should all know that using ANY Dexron/Mercon fluid is not recomended, and has shown to lead to transmission failure.

MOPAR ATF +3 is the factory fluid in all first generation LHs, and even earily 2nd gens. But, MOPAR has made a new fluid called ATF +4. Chrysler has posted a TSB saying that ATF +4 should be used now.

If you do switch to ATF +4, you must reset the TCM. Otherwise your shifts will become sloppy (which is why you may come accross threads saying that problems arose after they switched). The TCM can be reset by disconnecting the battery for 15min or more. After reconnection, take the car out driving how you normally drive. The TCM will do a learning procedure and adjust itself to the new fluid, and your driving.

Here is the TSB:

NOTE :THIS BULLETIN APPLIES TO ALL VEHICLES EQUIPPED WITH CHRYSLER AUTOMATIC TRANSMISSIONS EXCEPT 1999 AND EARLIER MINIVANS.

DISCUSSION:

A new transmission fluid (ATF+4(R) - Type 9602) has been developed and is being used as factory fill for all vehicles with Chrysler automatic transmissions. Until now, vehicles originally filled with ATF+2 or ATF+3 were to be serviced with ATF+3. Effective immediately, it is recommended that all vehicles with Chrysler automatic transmissions except for 1999 and earlier minivans be serviced with ATF+4(R). ATF+3 should continue to be used for 1999 and earlier minivans because of the potential for torque converter shudder during break in. For all other applications the ATF+4(R) fluid offers significant benefits as outlined below.
NOTE :ATF+4(R) MUST ALWAYS BE USED IN VEHICLES THAT WERE ORIGINALLY FILLED WITH ATF+4(R).

NOTE :SERVICE INTERVALS DO NOT CHANGE. THE SERVICE INTERVAL CURRENTLY IN EFFECT FOR A GIVEN VEHICLE SHOULD CONTINUE TO BE FOLLOWED.

NOTE :ATF+4(R) IS COMPATIBLE WITH ATF+3 AND CAN BE USED TO TOP OFF VEHICLES THAT CURRENTLY HAVE ATF+2 OR ATF+3. DO NOT USE ATF+2 OR ATF+3 TO TOP OFF VEHICLES THAT HAVE ATF+4(R) FLUID.

BENEFITS
^ Better anti-wear properties

^ Improved rust/corrosion prevention

^ Controls oxidation

^ Eliminates deposits

^ Controls friction

^ Retains anti-foaming properties

^ Superior properties for low temperature operation

FLUID COLOR

Mopar ATF+4(R) is a World Class Fluid having exceptional durability. However, the red dye used in ATF+4R is not permanent; as the fluid ages it may become darker or appear brown in color. ATF+4(R) also has a unique odor that may change with age. With ATF+4(R) fluid, color and odor are no longer indicators of fluid condition and do not support a fluid change.
