    ATF+4 Castrol vs. Valvoline vs. Redline vs. RP?

    I recently picked up a 2006 Jeep Grand Cherokee HEMI with 90k miles which has the 545RFE transmission. I picked up both of the Mopar filters and a Fel-Pro trans pan gasket and now I'm trying to figure out which ATF+4 to go with. The truck is my daily-driver and this week I'll be installing a 4"...
