What transmission fluid for 2000 Dodge Durango?

Answer 1

I do believe that 2000 is one of those goofy years where some Dodge vehicles had different Transmission Fluid than others. I do know that you should use ATF+4 to be on the safe side. 2000 may be able to use ATF+3, however ATF+4 is backwards compatible with all Dodge transmissions.

In other words you can use ATF+4 in a ATF+2 or ATF+3 transmission, or ATF+3 in a transmission that calls for the use of ATF+2.

Never use a "lower" +# in a transmission that calls for a higher +#. Eg. never use +2 in a +3, +3 in a +4, or+2 or +3 in a +4.

The lubrication/friction properties are different. Using a "lower grade" in a transmission that calls for a "higher grade" can and most likely will cause a shudder or vibration which you will feel primarily when the torque converter is going into "lock-up" at highway speeds.

If all else fails, your dipstick will tell you to "use only Mopar #_ _ _ _" You can call your dealer with that part # and they can tell you which Fluid you need to be exact. The reasoning behind that is there is a significant cost difference between the ATF+'s. Mopar fluid is very high, you are much better off going to your local Napa, or whatever and getting the correct grade there.
