Upshift Downshift
WARNING: This page is about a different car, the 2002 Mazda 626. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
- GEAR SELECT dial must be in "3/R" to get REVERSE gear.
- Upshifts and downshifts will be FIRM during this procedure.
- Pressure gauges may be removed from the vehicle during these tests.
- These tests should be performed on the road. If they are performed on the hoist, the technician may not feel all of the shifts when they are engaged.
- LED's will turn "green" when solenoids are activated and turn "OFF" when deactivated. Refer to the appropriate overlay for the proper status/shift sequence of the shift solenoids during upshift and downshift.
CAUTION:
- Selector lever must be in the D range position or internal damage could result. Do not shift to 2 or 1 range position.
- Verify that the GEAR SELECT dial is in "1" position. Move the selector lever into the D range. Depress the 3-2 timing/coasting clutch solenoid (3-2 T/CCS) button and accelerate the vehicle. If there is no vehicle movement, inspect the forward one-way clutch. If movement occurs, proceed to step 2 and continue diagnosis.
- Move the selector lever into D range and accelerate to 23 km/h {14 mph}.
Select second gear by rotating the GEAR SELECT dial to "2" position.
- Did the vehicle upshift to second gear?
- Did the appropriate shift solenoids activate/deactivate?
- Accelerate to 40 km/h {25 mph}
and select "3" position.
- Did the vehicle upshift to third gear?
- Did the appropriate shift solenoids activate/deactivate?
- Accelerate to 56-72 km/h {35-45 mph}
and select "4" position.
- Did the vehicle upshift to fourth gear?
- Did the appropriate shift solenoids activate/deactivate?
CAUTION:- The vehicle speed must be below 56 km/h {35 mph} before shifting the select lever to "1" position, or the transaxle could overrun.
- Reverse the order to downshift.
- Did the vehicle downshift from 4 to 3, 3 to 2, and 2 to 1?
- Did the appropriate shift solenoids activate/deactivate?
NOTE:
- 4-3 downshift will be harsh when using the transaxle tester.
