I have a 1991 Honda Accord lx 4dr automatic. The "S" light came on a couple of weeks ago and when I drove it, it would shift up slowly. When I turned it off and then back on, the car was fine. Now the light stays on and the car does not shift up at all from 2nd gear. and about 3 days ago, the car would not let me get out of P into R or D. So I had to put the key in the "shift lock" to get it out of park. I had a mechanic look at the car and he told me that I needed to get the transmission fluid changed and that would take care of the problem. I also had a friend of mine look at it, and he said the same thing. I cant helo but to think that I will have to get a new transmission. Will I have to get a new tranny if it is not the fluid???

 

it might be the drum inside ur tranny i have almost same problem i took to tranny place check is my drum wont shirft in to 2 gear is cost me 1645.35 dollar

 

The S light means the transmission computer detected a problem. You need to find the code it set to properly troubleshoot.

You have a blue two pin connector below your glovebox that is plugged into a dummy connector. You short that with a thin paperclip. Count the S flashes. Short Flash =1, Long Flash =10

ie, L S S S = 13

Post the code on here.

You can download a 91 shop manual from Online Manuals thread in the DIY Section. That will help you out a lot.

 

I had the same issue with my 97 accord and the d4 light flashing, I checked and cleaned the shift solenoids and it went away. You may want to try that

 

so i went to a transmission shop to get the fluid changed and while i was driving to the place, the car acted like it was in neutral even though i was in D4 and i couldnt accelerate. When I got there, they checked it out and told me that there is something wrong inside the transmission. My uncle doesnt believe that, so tomorow a friend of his is going to check the car out. Hopefully its nothing inside it, and the shop people were lying.

 

Get the code, and that will point you in the right direction.

Its quick and easy to do.

 

i am very hesitant to do that. because whenever i try to do something and my gut tells me not to do it and i do, it goes horribly wrong....is there another way to get the code?

 

Code can be obtained by 1) turning keyswitch to ON and 2) pulling back carpet on passenger side foot area. The ECU and TCU are in a module bolted to foot area of body. There is a clear window just to right of center on upper side of ECU/TCU module. It will blink the codes (red led blinking). Read the flashes as described by PAHonda.

good luck

 

ok so i think im blind. because i pulled back the carpet on the passenger side and I found the module, but when i turn the key to on, i dont see any blinking lights, or lightbulbs for that matter... just bear with me here

 

You have to look through a clear window on the cover to the inside of the module to see the LED blinking on the circuit board under the cover.

good luck
