AURLTX001 Diagnose and repair light vehicle manualtransmissionsFour-wheel drive, low rangeWhen 4L is selected, the front sleeve is moved rearwards. This introduces the transfercountergear into the gear train. Instead of the drive going directly from the input shaft to thetransfer rear output shaft, the counter-gear provides a reduction. The countergear is drivenby a constant-mesh gear on the input shaft, and it also drives a constant-mesh gear on thetransfer rear output shaft. When the sleeve is moved, it connects the constant mesh gear tothe output shaft. Drive now passes through the countergear so that the rear output shaft isdriven at reduced speed. The chain also drives the front output shaft at this reduced speed.
