Road Test
- With transaxle at normal operating temperature, operate vehicle with gear selector lever in "D" position with overdrive switch in ON position. Apply minimum throttle and observe speeds at which upshift occurs and torque converter clutch engages. See SHIFT SPEED SPECIFICATIONS
table.
- Stop vehicle. With gear selector lever in "D" position and overdrive switch in OFF position, repeat step 1
. Transaxle will make all upshifts except 3rd to 4th gear. Torque converter clutch application should occur above 50 MPH.
- Press accelerator pedal to Wide Open Throttle (WOT). Transaxle should downshift from 3rd to 2nd gear, or 3rd to 1st gear, depending on vehicle speed. Torque converter clutch should release.
- With vehicle speed above 30 MPH, move gear selector lever from "D" position to "1" position and release accelerator pedal. Transaxle should immediately downshift to 2nd gear. When vehicle speed drops below 20 MPH, transaxle should downshift to 1st gear.
- If transaxle fails to upshift/downshift or torque converter clutch fails to apply/release as specified, see appropriate SYMPTOM DIAGNOSIS (ELECTRONIC)
or SYMPTOM DIAGNOSIS (MECHANICAL)
under TROUBLE SHOOTING.
