    The S3 light works similarly to the check engine light. It will give you a series of blinks to tell you what is malfunctioning.

    How many times is it blinking?

      I performed a search on the web itself. This is what I came up with.
      1. (This Website will show a circuit diagram)
      http://autorepair.about.com/library/faqs/bl025i.htm

      2. (This Website will show all of the codes and their meanings. and a schematic of the Auto Trans. and the parts you will need to buy or find) http://www.acuraworld.com/forums/f74...uck-3rd-78656/

      The problem appears to be what I thought needed to be replaced. The 2 solenoids that sit on top of the Transmission towards the front. They are the control solenoid A & B (link #2 will show this).

      3. There's also another possibility. I just remembered when I removed my MFR(Main Fuel Relay) and attempted to start the car, The S3 light continously blinked. This replacement is not as costly about $65.00 at Acura. Or you can try Honda...just ask for the relay to a 90-91 Civic sedan EX- its usually cheaper - or even ask Acura to sell it at the Honda dealership price.

      I found this from Team Integra. This guy found all of the error codes from a Helms.

      Did some more searching and found this on another thread:
      The S3 light is the code the transmission is indicating an abnormal condition

      Under your dash, on the outermost driverside there is a control box for the Transmission. there is an LED display that will flash as well indicating what the malfunction is. this box is up about the same height the gauges are.

      The HELMS manual has a detailed breakdown of what the probable causes and fixes are for each code. I will give you a rundown of the codes for your AUTO 91 LS, but there is more detailed descriptions to the fault and fix.
      Pull your codes first, and let me know (in this thread)

            My issue with the S3 was the Main Relay also. I resoldered mine and the issue which is caused by cheap solder being used went away. There are write ups online for soldering the point in the relay.

              S3 light

              Okay so Iv checked the forums but im still confused. My s3 light blinks and sometimes im parked and the car wont start but the light doesnt turn on and when i take the key out the s3 light begins to blink. I also checked the number of blinks and last time i counted 73 blinks so idk if thats even a code or something else is the problem. So what should i do? change a specific part? And if so where is it located?

              Thankyou!
