- Remove the bolts holding the reaction shaft support (4) to the oil pump. see scheme 171
- Remove the reaction shaft support (4) from the oil pump. see scheme 171
- Remove all bolts holding the oil pump halves together. see scheme 171
- Using suitable prying tools, separate the oil pump sections by inserting the tools in the supplied areas and prying the halves apart. NOTE: The oil pump halves are aligned to each other through the use of two dowels. Be sure to pry upward evenly to prevent damage to the oil pump components. 1 - SEPARATOR PLATE 5 - DOWEL (2) 2 - DRIVEN GEAR (2) 6 - DRIVE GEAR 3 - FLAPPER VALVE 7 - SCREW 4 - PUMP HOUSING

TORQUE CONVERTER CLUTCH (TCC)
In a standard torque converter, the impeller and turbine are rotating at about the same speed and the stator is freewheeling, providing no torque multiplication. By applying the turbine's piston and friction material to the front cover, a total converter engagement can be obtained. The result of this engagement is a direct 1:1 mechanical link between the engine and the transmission.
The clutch can be engaged in second, third, fourth, and fifth gear ranges depending on overdrive control switch position. If the overdrive control switch is in the normal ON position, the clutch will engage after the shift to fourth gear, and above approximately 72 km/h (45 mph). If the control switch is in the OFF position, the clutch will engage after the shift to third gear, at approximately 56 km/h (35 mph) at light throttle.
The TCM controls the torque converter by way of internal logic software. The programming of the software provides the TCM with control over the L/R-CC Solenoid. There are four output logic states that can be applied as follows
- No EMCC
- Partial EMCC
- Full EMCC
- Gradual-to-no EMCC
