10 Easy Steps to Troubleshooting Your Acura Legend Transmission Problem

An automatic transmission is truly a marvel of modern engineering. Somehow the car knows when to shift gears up or down, depending on the acceleration and driving conditions the car is experiencing. Many people have never learned to drive a stick shift, which is a true testament to the success of the automatic transmission. But, as with so many modern technological advances, plenty can go wrong. There are many different symptoms of a bad transmission, from a jerky sound and feel when the car changes gear, to the car stalling altogether. While many transmission problems cannot be addressed by someone who does not have a mechanic’s background, there are several steps which can be taken to diagnose a transmission problem with a car, including an Acura Legend. The following information includes 10 steps to troubleshoot transmission problems with an Acura Legend.


1. Check the Fluid Level

A car owner should check their transmission fluid levels periodically. It is recommended that this be done at least twice a year. Checking the fluid level every time the oil is changed, about once every three months, is not a bad idea either. Lack of adequate transmission fluid can cause the transmission to change gears in a jerky fashion. Eventually, the transmission in the Acura Legend may not shift gears at all.

2. Examine and Smell the Transmission Fluid

Remove the dipstick, and then wipe it off. Dip it again into the transmission fluid and remove it. The transmission fluid on the stick should be red. If the fluid is black, or has a harsh burnt smell, the transmission fluid could be burning in the transmission. DID YOU KNOW?

Some mechanics and car experts say that changing the filter on a car’s transmission can resolve up to 90 percent of transmission problems. This simple and low-cost step should be done immediately after checking the Acura Legend’s transmission fluid level.

3. Check for Transmission Fluid Leaks

Sometimes Acura Legend transmissions will have a leak, causing the fluid level to change. A low level of transmission fluid can cause the transmission to change gears in a jerky fashion. There are only many places the transmission fluid may be able to escape from the housing. Check the following:
* Transmission drain hole
* The filler tube base
* And the connection between the transmission and the engine

4. Check the Transmission Filter

Check to see if the transmission filter on your Acura Legend looks dirty or clogged. This filter is an essential component related to the performance of the transmission, and hence of the automobile in general.

5. Replace the Transmission Filter

It may be a good idea to simply replace the transmission filter before taking your Acura Legend to the mechanic for further work. Even if a new filter was just put into the car, there may be some benefit in trying a different filter to see if the problem is relieved. This is a simple step, but is very important.

6. Get a Transmission Flush

A full transmission flush is recommended about every 30,000 miles, in order to get rid of any gunk which may have built up in the transmission of your Acura Legend over the past couple of years. If the car in question has not had a transmission flush in the past three years, or 30,000 miles, a transmission flush should be performed in order to see if this helps fix the problem. Also, this is an essential process for maintaining the transmission in good working order.

7. Check the Wiring

This step is a little more involved, but, give the transmission a casual look over. See if there are any wires coming to or from the transmission which seem loose or corroded. Tightening the wiring may help to fix the issue. If corroded wires are discovered, this will give the owner an idea as to one possible cause for the transmission problems in their Acura Legend.

8. Use the Diagnostic Port

The Acura Legend has a diagnostic port. A diagnostic device can be connected to this port in order to give diagnostic report of the transmission to the operator of the car. Using this information will help pin down just what the problem with the transmission may be. See the owner’s manual for more information about using this diagnostic port.

9. Search the User’s Manual

The Acura Legend owner’s manual may have additional steps for troubleshooting the transmission. Refer to the owner’s manual and follow any additional troubleshooting steps listed.

10. Search the Web

Many car owners have had success posting descriptions of their transmission issues on car forums, or even making a youtube video asking for help. Because purchasing an new transmission, or having the transmission in your Acura Legend rebuilt can be very expensive, it may be worth it to seek help online as a first step.


A problem with any car’s transmission is extremely frustrating because not only is it noticeable, due to the jerking and noise it creates, but also because it can be quite costly to fix. However, troubleshooting a transmission issue yourself can lead to a resolution which is both low-cost and easy to resolve. Follow these 10 easy steps, listed above, to troubleshoot the transmission problem with any Acura Legend.
