whats the best atf to use in G56?

[BTighe]

cold weather is making my truck hard to shift in the mornings. after reading a few threads it seems that the factory shorts us on fluid. should i add to whats in there (14k miles) or should i change it all? whats good and how much do i need? thanks

i used the amsoil ATF in mine, and man what a difference that made. shifts smoother and quieter across the board.

Every oil in mine is Amsiol. Works very well

BEING NEW TO THE DODGE/CUMMINS SEEN... . BUT AROUND DIESELS FOR 31 YEARS... . I TO... ARE CONCERNED ABOUT RUNNING THE STANDARD MOPAR atf +4 IN MY NEW 07 DRW 3500 WITH THE G56..... THE CUMMINS AND G56 IS THE ONLY REASON I BOUGHT DODGE... ... I WILL NOT RUN THE AMSOIL ATF CAUSE IT IS A MULTI-USE FLUID..... BUT VERY STRONGLY CONSIDERING THE VALONLINE SYN. ATF+4... . WHICH IS MADE FOR THE DODGE TRANS... BUT IS SYN... ... AND I FEEL THAT TRANS NEEDS A SYN. FOR THE PULLING IT IS MADE TO DO.....
