65rfe

  1. C

    65RFE Issue!! Lugging engine between 50-90kmh low rpm, struggles to downshift on light acceleration.

    65RFE 5.7 HEMI. No DTCs at all. rpms will drop to around 1000 and when lightly putting the pedal down the engine feels like it’s lugging and struggling to downshift. The TCC lockup is off during the problem. Line pressure is good. Anyone know what is actually happening?

    '13 65rfe to 8hp70 4x4

    I've got a 2013 1500 4x4 that I'm trying to swap an 8hp70 into but I'm struggling with the wiring aspect of the swap. Tons of forums I've seen use SGA harnesses, I could use one too but I want to keep the swap as close to factory as possible since I know the 2013s onward had an option for the...

    Trans unlocking/ locking + random downshifts

    Hey, yall, done a lot of research and really can’t find an answer or solution to what’s going on. What’s happening: torque converter repeatedly unlocks, then locks again, doesn’t matter the speed, trans temp, or outside temp. Trans will also downshift randomly, while driving steadily (almost...

    2015 8 speed swap

    So I've been doing some talking to people who know more than I. Actually it was Russell Drake. I know there is information on this forum for swapping the 8 speed into at least a 2013 or earlier. However after 2014 the 8 speed was a factory option. So I was told that since my ram is a 2015 that...

    2012 1500 Intermittent CEL

    Anybody have any idea what would cause an intermittent CEL when accelerating in overdrive? It also show up when lugging between 30 and 40 MPH. It wont stay on, only shows up for a few seconds and seems to almost go away if I drive it in tow haul mode. It is generally accompanied by what feels...
