I have a 16 lml tune and deleted ppei tunes... Converter is shuddering while Im towing my camper its happening around 70-75 mph in 6th gear. I installed a solenoid delete plug to increase the line pressure and this did not help. Other then the shudder the trans shifts perfect and when its unloaded it only does it occasionally and very lightly... Im going to install a new converter and was told that I should not run a triple disc converter with a stock trans. Is this a true statement? What are my options?
