Operation CHARM: Car repair manuals for everyone.

Test Drive Form

This schedule is intended to provide guidelines when test driving a car to evaluate complaints about the AW30-40/AW30-43 transmissions. Please observe local speed restrictions.

When test driving use the Volvo Scan Tool (ST) to obtain different values and functions.

Initial status before test driving:

- Check oil level in the transmission before test driving.
- Program selector set to mode E (Economy).

Test Driving
1 Check operation of the Park/Neutral Position Switch:

- Try to start the car with the gear selector in P - position.
- Try to start the car with the gear selector in a position other than P - or N -position.

2 Check gear selector positions:

- Check that the selector engages in each position, and that it does not try to jump out of the selected position.

3 Checking reverse gear:

- Back up the car as usual, ensuring that the backup (reversing) light comes on.

4 Listen for mechanical noises:

- Start in D -position. Drive the car so that the transmission shifts up and down. Listen for abnormal noises from the transmission. If noises occur, discontinue the test drive immediately, return to the workshop and fault-trace.

5 Verify transmission mode while driving:

Sport (S)
- Transmission should give quicker down-shifting.

Winter (W)
- Start in position D. The transmission should start in third gear and give a smooth take-up from standstill. Verify operation of kickdown.

Economy (E)
- Start in D-position. Check shifting speeds at lowest possible acceleration. Also note whether the gears slip or shifting is hard. Verify operation of the lock-up function. Lock-up will not engage at throttle openings of less than 4%.

- Start in D-position. Depress accelerator pedal (AP) to kickdown position (wide open throttle (WOT)). After the shift from 1st to 2nd, reduce the throttle to just below the kickdown threshold (85% throttle). Check gear shifting speeds for the appropriate engine variant. Note also whether the gears slip or shifting is hard. Check there is lock-up engagement on the fourth gear.

- Hint: Slowly accelerate. Press gently on brake pedal, maintain throttle opening. Lock-up should disengage.

- Start in D-position. Depress accelerator pedal to kickdown position at different speeds. Check the HIGHEST speed at which kickdown downshift occurs.

- With the car on a flat road with the gear selector in N -,release the brake and accelerate a little. Does the car move forward?

- Start in position 3. Drive until third gear engages. Release accelerator pedal and check whether engine braking occurs in 1st gear. Move gear selector to L -at a higher speed and allow the car to decelerate. Check the shifting points as the car slows.

- Start in position L. Accelerate and check that engine braking occurs.

- Move the gear selector to P -with the car stationary on an incline and release the brake. Does the car move?
