A/T Stall Speed Test

A/T Stall Speed Test

Test

1. Warm Up The Engine

Start the engine. Hold the engine speed at 3,000 rpm without load (A/T in P or N, M/T in neutral) until the radiator fan comes on, then let it idle.

2. ATF Level Check





1. Park the vehicle on the level ground.

2. Remove the ATF dipstick (yellow loop) (A), and wipe it with a clean cloth.

3. Insert the dipstick into the dipstick hole.





4. Remove the dipstick, and check the ATF level. It should be between the upper mark (A) and the lower mark (B).

5. If the ATF level is below the lower mark, check for fluid leaks at the transmission, the hoses, and the line joints. If a problem is found, fix it before filling the transmission with ATF.

NOTE: If the vehicle is driven when the ATF level is below the lower mark, one or more of these symptoms may occur:
* Transmission damage.
* Vehicle does not move in any gear.
* Vehicle accelerates poorly, and flares when starting off in forward and reverse positions.
* Engine vibrates at idle.

6. If the ATF level is above the upper mark, drain the ATF to proper level.

NOTE: If the vehicle is driven when the ATF level is above the upper mark, the vehicle may creep forward while in N, or have shifting problems.





7. If necessary, fill the transmission with ATF through the dipstick hole (A) to bring the fluid level between the upper mark and the lower mark of the dipstick. Do not fill the fluid above the upper mark. Always use Honda automatic transmission fluid (ATF) ATF DW-1. Using a non-Honda ATF can affect shift quality.

8. Insert the dipstick back into the dipstick hole.

3. HDS DLC - Connection





1. Connect the HDS to the data link connector (DLC) (A) located under the driver's side of the dashboard.

2. Turn the ignition switch to ON (II).

3. Make sure the HDS communicates with the vehicle. If it does not communicate, go to the DLC circuit troubleshooting.

4. Automatic Transmission Stall Speed - Test

1. Make sure the A/C switch is OFF.

2. Shift to D while pressing the brake pedal firmly, then press the accelerator pedal for 6 to 8 seconds, and note the engine speed.

NOTE: Do not move the shift lever or remove your foot off the brake pedal, while raising the engine speed.

3. Allow 2 minutes for cooling, then repeat the test in the all shift lever positions.

NOTE:
* Do not test stall speed for more than 10 seconds at a time.
* Record the engine speed at 6 to 8 seconds after pressing the accelerator pedal. Higher engine speed will be indicated for 5 seconds.
* Stall speed tests should be used for diagnostic purposes only.
* The stall speed should be the same in the all shift lever positions.
* Do not test stall speed with A/T pressure gauges installed.







4. If any of the stall speeds are out of the service limit, refer to the problems and probable causes listed in the table.
