Dakota 2WD L4-2.5L VIN P (2001)
7. Separate and remove driving shell, rear planetary and rear annulus from output shaft (Fig. 207).
8. Remove front planetary rear thrust washer from driving shell.
9. Remove tabbed thrust washers from rear planetary gear.
10. Remove lock ring that retains sun gear in driving shell. Then remove sun gear, spacer and thrust plates.
INSPECTION
Check sun gear and driving shell condition. Replace the gear if damaged or if the bushings are scored or worn. The bushings are not serviceable.
Replace the driving shell if worn, cracked or damaged. Replace planetary gear sets if gears, pinion pins, or carrier are damaged in any way. Replace
the annulus gears and supports if either component is worn or damaged. Inspect the geartrain spacers, thrust plates, snap-rings, and thrust washers.
Replace any of these parts that are worn, distorted or damaged. Do not attempt to reuse these parts. The planetary gear thrust washers are different
sizes. The large diameter washers go on the front planetary and the smaller washers go on the rear planetary. All the washers have four locating tabs
on them. These tabs fit in the holes or slots provided in each planetary gear. Inspect the output shaft carefully. Pay particular attention to the machined
bushing/bearing surfaces on the shaft and the governor valve shaft bore at the shaft rear. Replace the output shaft if the machined surfaces are scored,
pitted, or damaged in any way. Also replace the shaft if the splines are damaged, or exhibits cracks at any location (especially at the governor valve
shaft bore). The annulus gears can be removed from their supports if necessary. Just remove the snap-rings and separate the two parts when
replacement is necessary. In addition, the annulus gear bushings can be replaced if severely worn, or scored. However it is not necessary to replace the
bushings if they only exhibit normal wear. Check bushing fit on the output shaft to be sure.
ASSEMBLY
1. Lubricate output shaft and planetary components with transmission fluid. Use petroleum jelly to lubricate and hold thrust washers and plates in
position.
2. Assemble rear annulus gear and support if disassembled. Be sure support snap-ring is seated and that shoulder-side of support faces rearward (Fig.
