I have a brand new in the box never installed 2800 stall converter. It fits a a 4l80e. It's ar revmax stage3 rated for 500+ hp. This converter was upgraded with a woven carbon fiber lockup clutch and the 8 row accordion spring. With upgrades it cost$550 shipped. I'm asking $375+shipping from 79316. It weighs 30 lbs. There is absolutely nothing wrong with it and it's never been out of the box. I just purchased a sinister cam that is much larger than the small cam I have now. So I'm going to have to get a 3600 stall instead. 516661d1446224499-revmax-4l80e-converter-new-unused-2-1.jpg516660d1446224499-revmax-4l80e-converter-new-unused-1.jpg516661d1446224499-revmax-4l80e-converter-new-unused-2-1.jpg516660d1446224499-revmax-4l80e-converter-new-unused-1.jpg
