Hey guys/girls.. My 2016 has been having an intermittent slam when trying to lockup the torque converter. When the truck is in 4th (or 3rd in Tow/Haul) it seems like the torque converter locks up for a split second, then releases right away. Shortly after the converter will lock up completely and stay locked up as per normal. The stutter before has me concerned as it causes a harsh slam in the driveline. I know it's something to do with the converter as the TCC Slip PID drops briefly on my Ez Lynk (Tuned by Proven Diesel for the record). Anyone ever heard of this issue, bad solenoid perhaps? I've tried many different trans tunes and it happens on each tune. Only occurs once and awhile, sometimes it locks up perfectly first shot. Appreciate any input!
