 Five Star Torque Converter, Low Stall, GM 87+ 4L80E

Factory converters will fail with high mileage, greater than stock power and/or frequent towing. OEM units are typically made with stamped metal components and the stall speed is not matched to the engines torque curve.

ATS Five Star converters completely eliminate these weaknesses. They feature our patented square tab clutch design (for reliability during lock-up), ATS proprietary clutch material, CNC cut steels, re-designed stators, Torrington bearings and stall speeds matched to your engine. The Five Star Converters are designed to hold increase torque while efficiently transferring it to the transmission. The result is more power to the ground, lower transmission temperatures and greater overall performance.

ATS Five Star converters come with a 5 year / 500,000 mile warranty.

Is your 5 star converter a good replacement choice? What stall speed? I have an 04 H1 Hummer with a 6.5L TD

The ATS 5 Star is a great choice converter across the board. The stall speed is roughly about 1650-1700.
