System Operation - vehicles equipped with an 2.3L engine
First Gear Powerflow
In first gear, the shift shaft assembly pulls the 1st/2nd shift rail and fork back to slide the 1st/2nd synchronizer sleeve onto 1st gear to lock it to the output shaft. Torque is transferred from the input shaft to the counter shaft through 5th gear and from the counter shaft to the output shaft through 1st gear.
Second Gear Powerflow
In second gear, the shift shaft assembly pushes the 1st/2nd shift rail and fork forward to slide the 1st/2nd synchronizer sleeve onto 2nd gear to lock it to the output shaft. Torque is transferred from the input shaft to the counter shaft through 5th gear and from the counter shaft to the output shaft through 2nd gear.
Third Gear Powerflow
In third gear, the shift shaft assembly pulls the 3rd/4th shift rail back which pivots the 3rd/4th shift fork to slide the 3rd/4th synchronizer sleeve forward onto 3rd gear to lock it to the counter shaft. Torque is transferred from the input shaft to the counter shaft through 5th gear and from the counter shaft to the output shaft through 3rd gear.
Fourth Gear Powerflow
In forth gear, the shift shaft assembly pushes the 3rd/4th shift rail forward which pivots the 3rd/4th shift fork to slide the 3rd/4th synchronizer sleeve back onto 4th gear to lock it to the counter shaft. Torque is transferred from the input shaft to the counter shaft through 5th gear and from the counter shaft to the output shaft through 4th gear.
Fifth Gear Powerflow
In fifth gear, the shift shaft assembly pulls the 5th/6th shift rail back which pivots the 5th/6th shift fork to slide the 5th/6th synchronizer sleeve forward onto the input shaft to lock it to the output shaft. Torque is transferred from the input shaft to the output shaft through the 5th/6th synchronizer sleeve and provides direct drive through the transmission.
Sixth Gear Powerflow
In sixth gear, the shift shaft assembly pushes the 5th/6th shift rail forward which pivots the 5th/6th shift fork to slide the 5th/6th synchronizer sleeve back onto 6th gear to lock it to the output shaft. Torque is transferred from the input shaft to the counter shaft through 5th gear and from the counter shaft to the output shaft through 6th gear.
Reverse Powerflow
In reverse, the shift shaft assembly pulls the reverse shift rail back which pivots the reverse shift fork to slide the reverse synchronizer sleeve forward onto reverse gear to lock it to the output shaft. Torque is transferred from the input shaft to the counter shaft through 5th gear and from the counter shaft to the output shaft through the reverse gear and reverse idler gear to rotate the output shaft in the opposite direction.
