没有修发动机，只是换缸垫，变速箱没散，只是换了

Edelman picked the truck because the engine used mechanical injectors and the automatic transmission had a mostly mechanical valve body, which he predicted would be easy to maintain. He's replaced the transmission a couple of time; the last unit, which he rebuilt himself, has logged more than 600,000 miles. Alternators, starter motors, radiators, and water pumps have also been replaced.
