A look back at the 1963 – 1991 Jeep Wagoneer: A guide to year-to-year changes

Jeep Grand Wagoneer Selec-Trac Low Range lever

Jeep grand Wagoneer

1983-1991 Selec-Trac low range was engaged only when the vehicle was in 4wd since a sequential lockout system within the transfer case prevented low range operation in 2wd mode. A floor-mounted lever controlled engagement in and out of Low range, which was done only when the vehicle was stopped.
