Hello everyone, I’m new here, I have a 2007 edge with 135k miles. Trans has been shuddering when the torque converter locks up and if it isn’t shuddering it is locking and unlocking raising and falling 200 rpms. Won’t shudder until torque converter locked and is under a load like pulling a hill or if it locked up at low rpms and you get into it it will shudder, but if your just driving through town nice and easy it will just lock and unlock. I have replaced tss/oss and do not know if there’s something else to possibly fix or if it’s time to pull torque converter and replace. Thanks in advance and appreciate any help!

Was this ever figured out? My 2007 edge doing same thing, have replaced tss, and oss and still shudders and torque converter locking and unlocking, only shudders when torque converter is locking. I have to shut over drive off to get it to unlock to stop shuddering, if it is locked and not shuddering under acceleration, it will lock and unlock raising and lowering the rpms 200 rpms while doing that
