D Range Test: Notes

WARNING: This page is about a different car, the 2004 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

The NORMAL mode and SLOPE mode are automatically selected by the TCM in D range. The TCM shifts to SLOPE mode when the upgrade is approx. 5% or more, and shifts to NORMAL mode when the upgrade is approx. 3% or less.

Perform road test preparation. (See ROAD TEST PREPARATION .)
Shift the selector lever to D range.
Accelerate the vehicle with half and WOT, then verify that 1-2, 2-3, 3-4, and 4-5 upshifts and downshifts are obtained. The shift points must be as shown in Figure.
- If not as specified, inspect the TCM and ATX. (See SYMPTOM TROUBLESHOOTING ITEM TABLE .)
Drive the vehicle in 5GR, 4GR, 3GR, and 2GR and verify that kickdown occurs for 5-4, 4-3, 3-2, and 2-1 downshifts, and that the shift points are as shown. See Figure.
- If not as specified, inspect the TCM and ATX. (See SYMPTOM TROUBLESHOOTING ITEM TABLE .)
Decelerate the vehicle and verify that engine braking effect is felt in 5GR.
- If not as specified, inspect the TCM and ATX. (See SYMPTOM TROUBLESHOOTING ITEM TABLE .)
Drive the vehicle and verify that TCC operation is obtained. The operation points must be as shown in Figure.
- If not as specified, inspect the TCM and ATX. (See SYMPTOM TROUBLESHOOTING ITEM TABLE .)
  NOTE:
  - The shift solenoid electrical ON-OFF pattern in this chart describes the stabilized condition before and after shift control. The pattern may oscillate between ON and OFF momentarily while shifting-up or down. This is normal.
