4T65E Performance Torque Converter

2005 - Another PATC first. Developed a 245MM torque converter for 3.8L GM L67 supercharged motors with the 4T65E-HD transmission. This torque converter can be used with the stock L67 flywheel without the need to drill new torque converter bolt holes in the flywheel. Bolt the smaller 245MM torque converter to the existing flywheel without any changes. Stall speeds of 2200 to 4000 RPM can be ordered. The larger converter bolt circle is built right on the smaller converter. This is done with an adapter ring built onto the torque converter. Up until 3-18-2005 new torque converter bolt holes had to be drilled in the flywheel that was built for the 258MM torque converter.

#7-TR. 4T65E, 245 MM performance torque converter. It'll have a stall speed of 500 RPM or better over stock (you choose) and a carbon fiber clutch. The stock size torque converter is 258 MM on the 4T65E-HD transmission. A smaller lighter torque converter with a higher stall speed means more power to the wheels and faster times. This torque converter weighs 5 1/2 pounds less than the 258 MM converter. This torque converter fits L67 and L32 motors.  Cost $449.00 ($50.00 core refundable charge if you have a 258MM converter to return)
