Transmission, Manual—T50D

The T5OD is a five-speed manual transmission with 5th speed as an overdrive gear. The 1st through 4th gears and reverse gear are meshed within the case. The 5th speed gear and synchronizer are located on the back of the case in the extension housing. The floor-mounted shift lever operates a shift rail which extends from the extension housing turret to the shift cover. The 1st/2nd and 3rd/4th shift forks are mounted in the cover. The 5th speed synchronizer and reverse sliding gear are shifted through an intermediate lever mounted on a pivot pin. A shift interlock system, located in the cover, prevents engagement of more than one gear. The shift detent is located in the extension housing turret and consists of a detent plate, offset lever and spring-loaded ball. All gears except reverse are synchronized and helical cut for smooth, crisp shifts and quiet operation. Reverse is provided through a reverse idler gear which slides along a shaft to engage spur gears on the countershaft and output shaft. The case is aluminum and all fasteners are metric. The gear ratios for the 2.3L and 5.0L are shown in the following chart.

2nd	2.34:1	1.99:1
