ACDelco's Electronically Controlled Capacity Clutch, or EC^sup 3^, has been introduced to address such common transmission conditions as chiiggle and slippage. The EC^sup 3^ technology-patented In GM and released under the ACDelco brand name-expands the operating window ol the converter clutch by controlling the clutch. The engine and transmission can slip relative to each other in areas where full lockup svas not previously acceptable from an NVH standpoint. And, by allowing this partial lockup, driveline efficiency improves, resulting in enhanced fuel economy.
"Our customers have been asking for this technology and we're proud to be able to bring it to market," said Chris Thomas, GM Parts Powertrain Business Line Manager. "While our competitors have similar offerings, AC Delcos EC^sup 3^ technology is industry-exclusive because it's produced for original equipment (OE) GM applications only."
The EC^sup 3^ clutch is made from a special GM-patented friction material that allows the converter clutch to continuously slip, so drivers don't led the converter clutch engaging. In addition to helping to eliminate chuggle, EC^sup 3^ helps improve fuel economy. The EC^sup 3^ material-in conjunction with the vehicle's on-bourd computer-helps eliminate overheating.
The new torque converter pressure plates include the spring puck ussemblv to simplify installation. The EC^sup 3^ friction material is already bonded to the pressure plate to OE specifications, helping to reduce errors and to save technicians valuable time otherwise needed, to bond together a subassembly.
ACDelco is launching 10 new torque converter pressure plate assembly part numbers, eight of which include the EC^sup 3^ technology. Applications include select 1997 model year and newer GM cars and light-duty trucks.
