Drive Range

1. Position selector lever in "D" range, then accelerate vehicle from standing position.

2. Observe 1-2, 2-3 and 3-4 upshifts. Shift points should vary with throttle opening.

3. On models with Torque Converter Clutch (TCC), observe clutch engagement noting the following:

a. Clutch should engage in 3rd and 4th gears at 35-45 mph.

b. TCC will not engage if engine is not at normal operating temperature.

c. TCC should disengage when brake pedal is depressed.

4. On models with Viscous Converter Clutch (VCC), observe clutch engagement noting the following:

a. At minimum throttle, VCC should engage at approximately 24 mph with engine cold to 36 mph with engine at normal operating temperature.

b. Clutch engagement speed threshold can be increased due to high elevation, hot or cold coolant temperature at start, or high transaxle fluid temperatures.

c. VCC will not engage if coolant temperature is below 60°F or if Transaxle fluid temperature exceeds 314-343°F.

5. Verify forced downshifts, noting the following:

a. Part throttle downshifts should occur at varying throttle angles based on vehicle speed; low angles at low speed or higher angles at higher speeds.

b. As vehicle speed increases, downshift throttle requirements should rise until full throttle is required to effect a "detent" downshift.

c. Although 4-3 detent downshifts can be made at any vehicle speed, the 3-2 and 2-i downshifts be- come locked-out at higher vehicle speeds. Above the specified detent lock-out speed, throttle forced 3-2 and 2-1 downshifts should not be possible.

6. Verify that coasting downshifts occur sequentially as vehicle is coasting to a stop, and that transaxle starts off in first speed after coasting to stop.
