Hey guys. I’m running into a check engine light for “torque converter circuit open.” This entire powertrain was in another Jeep, it was swapped into the current Jeep along with wiring harness, computer, every single thing that was in the parts Jeep. I drove the parts Jeep around a ton before doing the swap and never had a light. Also worth noting, when it’s super hot outside, around 100 degrees, after driving for about 30 min the tranny makes a thumping/clunking noise in what seems to be the bellhousing area. Only noticeable when stopped. Does not do this any other time except when super hot. Tranny shifts fine, torque converter engages and disengages perfectly fine. It didn’t do this before the swap, but the tranny was never disconnected from the motor at all. Could this be a fuse issue or pigtail on the tcc plug or something? Thanks in advance
