I build my on trans but JPT TRANS in Eaton Rapids MI (517) 663-0578 did all machine work and built converter that is a 8" 5500 stall. Was all stock w 2.75 gear set till 2 weeks before mopar nats broke input shaft out of low drum. I replaced stock low drum and aluminum high drum. I just rebuilt and put 2.45 gear set has high and low aluminum drums in it now. To keep from draging bumper again.
