A604/ A606 Large Diameter Converter Upgrade

Updated Steel Cover (Eliminates Cover Leaks)

Updated Steel Piston (Eliminates Piston Distortion)

The OEM designed converter is prone to cracking and leaking at the mounting pads. In addition, high line pressure spikes warp the OEM designed lockup piston. Eliminate these costly comebacks by upgrading to the Super Heavy Duty series.
