That is the point I am making, ATF+4 is just adequate. The poster wanted to know if there was anything better, and IMO there certainly is.
Case in point,When Dodge decided to go with ATF+4 in the NV T-850 manual trans the OCI was changed from 48k miles to 18k miles(whats that tell you), so I swapped it out every 18k until my warranty expired and the fluid was nearly shot.
Now I am running RP Synchromax in the T-850, the shifting quality is night and day.After talking with MolaKule I am going to try a Synchromesh type fluid next, which is what the T-850 was originally designed to use.
