i have a newly built ~7000 miles on it.. billet 5r110 behind my cummins. put the upgraded direct and pressure solenoids in the trans.. every gear shifts GREAT. like perfect except the 3-5 shift.. it feels like im getting rear ended.. it hits so hard when towing it makes the goose neck hitch move and rattle pretty bad.. I just changed fluids.. nothing weird in bottom of the pan or anything but holy hell its bad, only on the 3-5 though.. its using the GPZ Extreme rebuild kit so it has all the extra clutches. think I should go back to the normal direct solenoid? I don't really want to do that if it could be something else. it just a waste of fluid, trans tuner cant tune it out. tried factory 3-5 shift tunes, tried "less than" 3-5 tunes to soften it up and nothing.. its harsh harsh regardless..
thanks for any info yall can shed..
