    ATF 4.....Is there a difference?

    Is there any differences between all the brands of tranny fluid which would make one better than the other?

    Rumor is that Valvoline produces Mopar brand. I used some of the Valvoline ATF recently after a torque converter swap without any problems.

    In order for any brand of fluid to say ATF+4 it has been tested by Chrysler to meet their standards for the fluid.

    So you'll be fine with any ATF+4

    Okay, sounds good. I was just thinking about it since synthetic oil has Royal Purple who people swear by and wondered if there was a company out there that has done some fancy chemical engineering to produce a better tranny fluid.
