Road Test
NOTE:
If shift lever cannot be moved from "P" position with brake pedal depressed and accelerator pedal at idle position, check shift interlock system. See appropriate SHIFT INTERLOCK SYSTEMS article.
- Warm engine to normal operating temperature. Apply parking brake and block wheels. Start engine. Move shift lever to "D4" position while depressing brake pedal. Depress accelerator pedal and release it suddenly. Engine should not stall.
- Repeat step 1 with shift lever in "D" position. Ensure engine does not stall. Manufacturer recommends monitoring of Throttle Position (TP) sensor voltage when performing road test to ensure proper throttle opening for verifying shift points and lock-up of torque converter.
- Remove right door sill molding and lower dash panel and remove small cover on right kick panel. Pull carpet back for access to Powertrain Control Module (PCM), located on right footwell. See Fig 1.
- Remove PCM cover located above PCM. Ensure ignition is off. Install Backprobe Test Set (07SAZ-001000A) or equivalent between PCM and DVOM leads. See Fig 1. Using DVOM, with positive lead at terminal D6 and negative lead at terminal A26. See Fig 1. Ensure DVOM is set for measuring voltage.

- Road test vehicle and check for abnormal noise and clutch slippage. See CLUTCH APPLICATION table for clutch engagement.
- Ensure upshift and downshift points and torque converter lock-up are correct in relation to throttle position sensor voltage or throttle opening and vehicle speed with shift lever in "D4" position. See TRANSAXLE UPSHIFT SPECIFICATIONS and TRANSAXLE DOWNSHIFT SPECIFICATIONS tables.
- With shift lever in "D4" position, accelerate to about 35 MPH so transaxle is in 4th gear. Move shift lever to "2" position. Ensure engine braking occurs.
CAUTION:
DO NOT shift from "D4" to "2" at speeds greater than 62 MPH or transaxle may be damaged.
- Place shift lever in "1" position. Accelerate from a stop at full throttle. Check for abnormal noise or clutch slippage. Upshifts and downshifts should not occur in this shift lever position.
- Place shift lever in "2" position. Accelerate from a stop at full throttle. Check for abnormal noise or clutch slippage. Upshifts and downshifts should not occur in this shift lever position.
- Place shift lever in "R" position. Accelerate from a stop at full throttle. Check for abnormal noise or clutch slippage.
- Park vehicle on a slope. Apply parking brake. Place shift lever in "P" position. Release parking brake. Ensure vehicle does not move. If vehicle moves, check for defective shift cable or parking components.
- Ensure ignition is off. Remove test harness and reinstall electrical connectors, PCM cover, carpet and door sill molding.
