Not sure if that’s something that would help.
Getting a healthy 57 to be happy locking isn’t hard they were the first aftermarket converter with the very efficient medium duty pump. Other Companies finally followed that trend within the past few years started utilizing that pump more.

Be interesting to see how many trucks with 340 gears have a lock up problem if any.

Exactly^ mine works the same, every time. Even at 1000+whp. No codes, just lockup when itís supposed to.
