Our transmissions have been completely disassembled, cleaned, and examined thoroughly for wear, breakage, and distortion. All parts have been measured for wear, and only those components that meet manufacturer's specifications are used. They are then reassembled and fine-tuned to ensure that all tolerances and clearances are measured and adjusted to the optimal specification. We add new o-rings, seals, and gaskets, and we use high energy steel and friction clutches, new differential bearings, a heavy duty torque converter, a new internal filter and an add-on inline cooler filter where applicable. We then test the transmissions on our dyno to make sure it works as it should.
