I retired from the military in 2005. I now teach automotive technology. I have been in the maintenance field since the early eighties. I am one of those guys who is never satisfies until its done right and never quit learning. I was fortunately brought up by my father who had a gift with his hands. His legacy is carried on through me. From welding to Wiring in a house.
I have taught electronics, automotive hydraulics, electronic transmissions and troubleshooting. Most of it gained through experience.
One of the gates I built.
I am a moderator at the diesel place website for the 4L80-E transmissions
