the Jeep Grand Wagoneer was last made in 1991. do you mean the Jeep grand Laredo or Jeep grand Cherokee?
TJ is not an abbreviation for anything, its just Jeep's designation for the 1997-2006 Jeep Wrangler. After World War Two, Jeep made vehicles for non-military use. They were designated "CJ" for "Citizen's Jeep". In 1987, Jeep had a major renovation of the Wrangler and designated it "YJ". Again a major design change took place in 1997, and the new Jeep was called the "TJ". The letters don't mean anything though.
