We took the rebuilt 4L80E over to Race Trans, a small shop known for its truck and diesel transmissions. The tranny was run on a dyno to make sure all line pressures and shifting was correct. Additionally, the torque-converter lockup was verified as working since we didn't want to be pulling this transmission out again any time soon if it could be helped.
